A relatively incomplete documentation.

Filed on: [Indigo]<Chipndale>5.2>Documentation>Chipndale17.tioga

Abstract: Chipndale, son of Chipmonk, is an interactive graphic layout tool made to run in Cedar. Chipndale makes use of multiple windows, extensive parallel processing, vast amounts of memory, pop-up menus, and other assorted goodies. When complete, Chipndale will have a DRC and circuit extractor, a fast set of IO and checkplot routines, and modular device extensibility. What's more, everything in Chipndale will be completely technology independent, that is, all the features will be equally at home dealing with PC boards or CMOS chips. This document details the current state of development.

0. Introduction

0.1. Background

Originally called Chipmonk II, Chipndale1 is the Cedar successor to Chipmonk, an interactive layout editor written for the Alto world. But although Chipndale looks a good deal like Chipmonk, there are still distinct dissimilarities. Like Chipmonk, combinations of keyboard and mouse commands allow creation and modification of both primitive (contacts, transistors) and constructed (cells) objects. Multiple views of a design are available on both the color and B&W displays. Chipndale can read in old Chipmonk files and some Chipndale designs can be written out in Chipmonk format. Unlike Chipmonk, Chipndale incorporates the concept of "technology independence", the idea that separate technologies (NMOS, CMOS, PC boards, etc.) do not interfere with the basic Chipndale kernel, nor do they interfere with one another. New technologies may be created with their own definitions of commands and structures, allowing Chipndale to expand to accomodate new methods and applications.

Although the functionality available has for the most part been specified, the access route to those capabilities is not well established. The mapping of commands necessary to invoke specific functions is evolving as the user interface becomes more refined. The moral of the story is:

The ice you are skating on is currently under development; it is apt to be thin in places.

This is not the best of all possible worlds. But don't get mad, get even; that is, if you are miffed at obvious shorcomings, send us mail (ChipndaleImplementors^.pa or ChipndaleDiscussion^.pa). We won't know about it unless you tell us.

The rest of this introduction will provide you with step-by-step information to start Chipndale and read in either Chipndale or Chipmonk design files. The rest of the document is intended as a reference manual; use the "Levels" button to scan the document for the general section you are interested in reading. The amount of descriptive detail increases with the number of visible levels.

0.2 Getting Started

Saying Hello

Go find yourself a Dorado running Cedar 5.2 and login. Use the DF Tool to bringover the file:

/indigo/chipndale/5.2/top/cddesign17.df

It is usually best to create a separate subdirectory for Chipndale; this allows you to remove it easily when you want to upgrade to a new version. This DF file will equip the machine with all the information it needs to run the NMOS, CMOS, and Chipnsil versions of Chipndale. If you cannot find a Dorado, don't know how to login, or generally have trouble with any of the commands, ask a nearby Dorado-user to help you out. Or you can read the basic documentation available on:

[Indigo]<Cedar5.2>Documentation>HowToUseAPublicCedarMachine.tioga

Becoming Acquainted

To get a design up on the screen, start up a session of Chipndale (in the same subdirectory containing its files) with one of the following incantations:

% CDRead <optional name of a chipndale design file> or

% CDReadCMNMOS <optional name of a chipmonk NMOS design file> or

% CDReadCMCMOS <optional name of a chipmonk CMOS design file>

(the latter two stand for:

ChipnDaleReadChipMonkNMOS and ChipnDaleReadChipMonkCMOS)

These commands will call up the Chipndale Terminal monitor (hereafter referred to as "Terminal") and will display the design on the screen. Terminal keeps a log of all the commands issued concerning Chipndale; it is where you will look to find information about what Chipndale is trying to execute and how that execution is progressing.

It is important to know what technology the chip was designed for when you are reading Chipmonk files so that you use the correct form of the read command. (The Chipndale design files know their technology, however the code handling that technology must be loaded before issuing the CDRead command). If no filename was given to the command, Terminal will respond with the request:

Input file >

Type the file name in at the prompt. The file may either be present locally or on one of the file servers; default is either a ".dale" or a ".chip" file depending on the command. For example, you could read in a file either as:

/ivy/monier/aspen

or as:

aspen.chip

if it was already on the local disk. You usually do not need to type in the extension.

If all is going well, the file will be read in and a Chipndale viewer containing the design will be opened on the screen. A control panel will also appear in the lower right of the screen whose buttons are functionally similar to the buttons available at the bottom of the Chipmonk screen.

2. Commands

In General

Chipndale commands are grouped such that those most frequently applied use the lefthand side of the keyboard. This grouping allows easy finger placement without having to move your right hand from the mouse. This speedy access, however, has outweighed mnemonics, which is why "Q" draws a transistor, not "T". Infrequently used commands have been shuffled off to the righthand side of the keyboard.

The mouse are ordered such that the middle button controls drawing objects, the left and right buttons control modifications. Drawing only occurs when the middle button is pressed or held down; alterations only occur when the left or right button goes up.

These commands refer to the 7-28-84 version of the default Chipndale tip table. If you apply any of these without the expected result, check the mapping of the tip table you are using.

2.0. Selection

Select Single Object

Left

Point to desired object and hit Left mouse button. All previous selections will be removed. (Note: just the condition of being selected is removed, not the object itself!)

Select Closest Object

<ESC>-<TAB>-Left

Holding down <ESC> and <TAB> when hitting the Left mouse button will single-select the closest object. All previous selections will be removed. Appears to be closest object within a certain radius?

Select Covered Object

<SHIFT>-Left

Holding down <SHIFT> while hitting the Left button will cause the selection to rotate through the possible objects at that point. This enables you to select objects completely obscured by other overlaying structures.

Select Multiple Objects

Right

Selections made with the Right mouse button will be added to the collection of previously selected items.

Deselect Object

<SHIFT>-Right

Point to a selected object, hold down <SHIFT> and hit Right. Selection will be removed.

Select/Deselect All

<ESC>-Right, <ESC>-Left

Hold down <ESC>: hitting the Right mouse button selects everything in the current design, hitting the Left mouse button removes all selections.

Select Entire Layer

<ESC>-<SPACE>-Right

Hold down <ESC> and <SPACE> then hit the Right mouse button; all of the objects belonging to the current layer will be selected.

Change selection

<SPACE>

If you are selecting an object but have not yet let the mouse button up, you can change your choice by keeping the button down, moving the mouse to the new object and hitting <SPACE>. This change in midstream will also work even if you are about to execute a command on the selected object.

For example: Say you want to rotate something. You press R, point to the appropriate object and press the Left mouse button. As soon as you let the button up, the command will be executed. But wait! You really wanted the object just to the right! No problem. Keep the mouse button and the R down, move the cursor to the new object, and hit <SPACE>. The selection will be switched to the new pointed objected. Now when the mouse button is released, the new object will be rotated (either in place of or in addition to the old object, depending upon whether the Left or Right mouse button was used).

2.1. Drawing wires, move and copy, transformations

Change Level

Change level by hitting the associated level number key. These commands are similar to the contact commands except that the middle button is not held down.

<1>

set layer to be N diffusion

<1>-<LOCK>

set layer to be P diffusion

In general, if the <LOCK> key is down, everything is done in the P-diffusion world; <LOCK> up indicates N-diffusion. This doesn't work in all cases but that's the idea. You can change between pdif and ndif just by switching the position of the <LOCK> key without hitting <1>.

<2>

set layer to be poly

<3>

set layer to be metal

<4>

set layer to be N-well contact

<5>

set layer to be N-well

<6>

set layer to be 2nd level metal

Wires

Middle

Pressing the Middle button and moving the mouse draws a wire, releasing the button confirms the position and length of the wire

<SPACE>

Hitting <SPACE> while drawing a wire flips the orientation of the direction the wire bends

<SHIFT>

Hitting <SHIFT> while drawing a wire confirms a wire segment

<ESC>

Stops the wire drawing process

Move and Copy

Q-Right

Move selected objects to current cursor position

Moves entire collection of selected objects relative to the former cursor position as indicated by the vector drawn on the screen when moving the mouse.

Q-<TAB>-Right

Copy selected objects to current cursor position

Copies entire collection of selected objects by choosing an origin with the left mouse button, holding that button down, and moving the cursor to the desired destination.

Q-Left

Move pointed object to current cursor position

Identical to Q-Right save that the only object moved is the one pointed to by the cursor and all former selections are removed.

Q-<TAB>-Left

Copy pointed object to current cursor position

Identical to Q-<TAB>-Right save that the only object copied is the one pointed to by the cursor and all former selections are removed

Rotate

R-Right

Rotate the selected object(s) by 90 in a clockwise direction, the bottom left corner remains fixed.

R-Left

Rotate the pointed object by 90 in a clockwise direction, the bottom left corner remains fixed

In order to rotate the design 90 degrees#clockwise, select the entire layout by using the select-all command <ESC>-Right. Now indicate a rotation with R-Right. The design will be rotated keeping the bottom left corner fixed. As long as the design is selected, hitting more R-Right's will continue the rotation. This command sequence is useful in conjuction with the plotter routines.

Step Left/Step Right

Note that "A" is on the left of "S"

A-{Left or Right}

Move the selected object(s) one lambda to the left.

S-{Left or Right}

Move the selected object(s) one lambda to the right.

2.2. Transistors and Contacts

Transistors

All commands executed by hitting the middle mouse button

Place n-transistor at current cursor location

Q-<SHIFT> or Q-<LOCK>

Place p-transistor at current cursor location

Draw angle n-transistor at current cursor location

W-<SHIFT> or W-<LOCK>

Draw angle p-transistor at current cursor location

Contacts

All commands executed by hitting the middle mouse button

<1>

Draw N-dif contact

<1>-<SHIFT>

Draw P-dif contact

<1>-<2>

Draw N-butting contact

<1>-<2>-<SHIFT>

Draw P-butting contact

<1>-<TAB>

Draw N-buried contact

<1>-<TAB>-<SHIFT>

Same as <1>-<TAB>

<2>

Draw poly contact

<3>

Draw metal-metal2 contact

2.3. Changing objects

Widen, Narrow

Lengthen, Shorten

Stretch

A-<CTRL>-{Left, Right}

Move pointed side of object(s) one lambda to the left

Using the Left button acts on only the object currently pointed to; the Right button acts on all selected objects. You must be pointing to a selected object each time the mouse button is pushed. If object is shrinking (due to having its right side moved over), it will stop moving when its width reached one lambda, regardless of how many times the command is given.

S-<CTRL>-{Left, Right}

Move pointed side of object(s) one lambda to the rights

2.4. Viewer commands

Change scale

".", ","

Hitting <PERIOD> decreases magnification; hitting <COMMA> increases it. It is easier to remember these commands by looking at the upper case options on the keys, that is, "<" decreases the scale and ">" increases it.

Change position

<SPACE>-Middle

Moving the mouse while holding down both the <SPACE> key and the middle button draws a vector on the screen. The view of the design will be moved in proportion to that vector when the mouse button is released.

View all

<SPACE>-Middle

Holding down <SPACE> and clicking the Middle button will cause the viewer position and scale to change so that all objects are vilsible on the screen.

View all selections

<SPACE>—Left

Holding down <SPACE> and clicking the Left button will cause the viewer position and scale to change so that all selected objects are visible on the screen.

2.5. Cells

Create cell

X-C-Middle

Create a new cell from the set of all selected objects. Terminal will prompt for a unique cell name.

Draw cell

C-Middle

Draw cell placing origin at current cursor position. Terminal will prompt for name of cell to be drawn.

Push-Pop

C-Left

Push into cell: the rest of the design will be darkened

C-Right

Pop out of cell

Cell directory

<SPACE>-D

Directory pop-up menu:

list directory: list contents of directory

clean up: list unused entries, and ask whether they should be removed from the directory.

remove ob:

rename seleced ob:

list imports: list names of imported designs

list importee: list referenced object of a particular imported design

CELLS: calls Cells pop-up menu

Macro's for Chipnsil

See this space for future developments.

2.6. IO, Imports, and Includes

<SPACE>-O

Use the IO pop-up menu. Default extension is .dale. Is there a single command?

Chipmonk IO

<SPACE>-I or <SPACE>-O

The IO pop-up menu allows to create backwards compatible chipmonk output. (.chip file). Not all Chipndale features can be written onto Chipmonk compatible files. This command is restricted to CMOS and NMOS IC designs.

Imports

See this space for future explanations.

Include

See this space for future explanations.

2.7. Repetitions

Description

Commands

<R-middle>

Make a repetition of the selected objects

<I-CTRL-SHIFT>

Decrement count on selected objects (repetitions)

<I-CTRL>

Increment count on selected objects (repetitions)

Any repeated object has the possibility to ask what index it has in the repetition.

2.8. Properties, SignalNames

Properties

It is possible to hang arbitrary properties to any application of objects. These properties may or may not affect any program's behaviour, or may only be comments for designers. Programs can protect their properties from designers, so the property mechanism can be used without danger of contention.

<SPACE>-P-Left

Shows all the properties of the selected application

P-Middle

Asks for a property name and allows to replace the value of the property. Properties included interactively cannot make use of all the nice Cedar types, however, a pop-up menu allows you to select the types of the property value in some limited range. Prefered types for properties are Rope.ROPE, ATOM and REF INT. The name of a property is always converted to an ATOM.

Properties using these types are saved while a design is written on a file and read back. However, clientprograms may affect this and force a different behaviour for properties they own. Such properties are usually reserved by the implementor for his/her exclusive use so designers will not be surprised. It may be good to load client programs first, and only thereafter use undocumented properties; they might be disabled by a client program, even if it runs later.

-Need and example here.-

One of the uses of properties is for communication with procedures evaluating conditional objects: these procedure have the possibility to query all their containing applications for arbitrary property values.

Signal Names

$SignalNames are reserved properties. Their value should be a ROPE. =

N-Middle:

Enter signal name

N-Left

Display signal name

3.2. Plotting on the Color Versatec plotter

Creating The Plot

<QUOTE>-Left

You cannot plot on both, the black and white and the color plotter at the same time, since the same command is used.

Bringover the file [indigo]<chipndale>5.2>top>colorvplot16.df with the DF tool. (16 is the current chipndale version, keep this number up to date, independantly of this documentation).

- All of Chipndale will be broughtover if not already present.

- You should bringover to the subdirectory from where you run Chipndale.

Independently whether Chipndale is already running or not, execute the command:

%VersatecCMOS or

%VersatecNMOS

to set up the appropriate software and colors.

Now you need to get your design on the screen (if it's not there already). Execute one of the following:

% CDRead <name of Chipndale file> or

% CDReadCMCMOS <name of Chipmonk CMOS file> or

% CDReadCMNMOS <name of Chipmonk NMOS file>

to read in your ".chip" or ".dale" file.

Plot any portion of the design you wish by selecting an area using the left mouse button with 'quote' held down. Terminal will request the number of vertical strips of paper you want the plot plotted on; each strip will be made into a pd file named "plot(i).pd" where i is 0..(#strips -1). The plot will be made as wide as the given number of strips will allow. In each strip, a '.' will be printed for every horizontal band as it is completed. An arrow will travel down the plot indicating portion of the plot under consideration; the phrase "finished plot(s)" indicates that all strips have been done.

Sending To The Versatec

%peach belle <name of pd file>

The Versatec must be in "Soliciting Client" mode before it will print your file. If it says "Got a Client" and the LED display indicates disk activity, someone else is probably sending a file and you'll have to wait. If it is not busy and does not say "Soliciting Client," punch the white boot button on the front of the machine (the one next to the red button, above the LED's) and wait for the correct prompt to appear.

To start sending the PD file, give the command:

%peach belle <name of pd file>

and the file will be transferred over the net to Belle, aka the color Versatec. A pie-shaped icon will appear indicating the portion of the file that has been transferred. The Peach software will wait for Belle to be ready before starting to send the file. If you are waiting for the file to start being transferred, it might be a good idea to check whether Belle is really busy or just needs rebooting. Do NOT reboot if the LED indicates disk activity ( displays some percentage of CPU utilization less than 100 and greater than 0).

Completed plots are cut off each night and left for pick-up on a table in the Purple Lab. Users are strongly discouraged from cutting off their own plots. (It is fairly difficult to install the paper properly such that the next user gets a good registration on his/her plot.)

Color Selection

Description

Example

You can easily change the colors assigned to levels by editing the command files VersatecCMOS.cm and VersatecCMOS.cm.

3.3. Plotting on the Black and White Versatec plotter

Creating the Plot

You cannot plot on both, the black and white and the color plotter at the same time, since the same command from the tip table is used.

Run the vplot module by "run vplot" in the user exec, or have it run by the "Chipndale.RunPrograms" userprofile option.

Manipulate the design in the viewer so that you can see the entire amount of information you want to print. Hold down <QUOTE> , and with the left button down, draw a rectangle containing that part of the design that you want to come out on paper. When you release the button, Terminal will ask you to select the number of strips you want the design to be printed on (for all you VLSI wallpaper fans). A new viewer will appear, showing the middle of the horizontal stripe currently under consideration. An arrow pointing to the design will show you how far the transfer has progressed. After the transfer is complete, the connection to the Alto will be closed and the Trident file "plot.bits" will be printed on the Versatec. This routine should not break even on large and complex designs.

3.4. Using the Color Display

On and Off

Chipndale also uses the color screen as a viewer. Type the command:

% colordisplay

to enable the display. The cursor will now move off the side of the display onto the color screen as though the two were contiguous. Use the command:

%colordisplay off

to get rid of the colordisplay and retrieve the left boundary of your screen.

You can set up the color screen for chipndale with your user profile. CDPattern reads in a pattern from a pattern file of chipmonk, specify which file by using the userprofile. CDColorMap reads in a chipmonk colormap.

Moving Between Screens

The viewer bar will contain the extra option "Color" when the color display is enabled; this button will toggle the viewer between the B&W and the color screen. The "-->" and "<--" buttons can also be used to swtich the viewer over from the color display.

4. Chipndale and Chipmonk

4.1. Quick introduction for veteran Chipmonk users

Wires

To draw wires just press the middle button and move the mouse.

<SPACE> while the button is still kept down flips the wire

Releasing the middle button draws the entire wire.

<SHIFT> while the button is stil kept down draws a segment of the wire.

Menus

<G> displays a global menu

<V> displays a viewer menu

Selection

<SPACE>-Mark shows the selected Rect on an this viewer

<SPACE>-Select shows the selected Rect on an OTHER viewer

Viewers

<SPACE>-Draw moves this viewer

< grows the design (see more detail on smaller part)

> shrinks the design (see more in less detail)

/ shows positions of other viewers

All the other commands are analogous to Chipmonk or inherently obvious (cross fingers).

4.2. What's really different from Chipmonk

Some few commands...

All the fuss about technology independency. It's more than you would expect.

Large designs, (32 bit numbers)

Easy to use for clients: All usefull commands can also be accessed from calling procedures: Open ended client interfaces.

It's own implementation is based on the client interfaces.

It's list of object types is open ended, including their representation on files.

Multiple viewers per design.

Multiple designs.

Runs on Cedar, gets all the advantages of an integrated environment.

NMOS and CMOS are incompatible, they are implemented as different technologies.

Pop-up menu's.

Terminal viewer for log.

Imports of (References to) other designs

Real repetitions

Conditional objects.

Use of property lists.

Checklots on both color and B&W Versatec plotters.

4.3. What's missing in Chipndale

DRC

Analysis, Extraction,

Some programs which run in Chipmonk

Pla generator, Rom maker, ... its all in progress

CIF generation, EBES mask generation

once worked, but needs to be updated

Feedback from real designers

is really missing
