INTRODUCTIONMagic is a system providing Multiple Analyses of the Geometry of Integrated Circuits. Thesystem is configured as a framework providing commonly used facilities, on which separatemodules implementing the various analyses have been implemented. As such the system isextensible as more input formats and analyses are required. Currently input from CIF 2.0 andIcarus format files is supported. The following analyses are implemented: viewing on thescreen, outlined plots on the Versatec plotter, color Press output, Mead/Conway design rulechecking, switch level circuit extraction (with subsequent electrical rules checking andsimulation, see Magic), and conversion to various other formats including filtered CIF, Icarus,and Mann 3000. 1.1 AcknowledgementsTo Bob Hon for provision and maintenance of the CIF Parser and Interpreter that provide thebasis for the core of the system. To Forest Baskett for the electrical rules checking analysis.Also to the many people who have provided much valuable feedback from earlier versions ofthe system.2. OPERATIONMagic is implemented as a set of programs in Mesa. Although the core of the system will runon an Alto, most analysis modules will run only on a D machine. This results principally fromthe difficulty of using more than 1 bank of memory for data structures on an Alto.The basic Magic system is implemented in Mesa, and the user interface is provided by runningMagic under the interactive programming system JaM [JaM]. JaM provides a simple interpreterthat supports the JaM programming language, and from which Mesa programs can be called.For the purposes of this document the term Magic will be used to cover the combination of thebasic implementation and the JaM user interface.2.1 Input FormatsLayouts can be specified to Magic in one of two formats: Caltech Intermediate Form (CIF) orIcarus, or as a combination of both.2.2 UsageMagic can be used either interactively or via command files. The command files provide a verysimple interface to the more commonly used functions. More involved analyses require usingMagic interactively, which therefore requires a knowledge of JaM. This document does notinclude a JaM tutorial - the reader is refered to the JaM manual [JaM].Typical usage involves retrieving a command file from Indigo for the analysis required, andexecuting it to retrieve the necessary programs and files. This step is necessary for only the firstusage. One of the files will be a .do file whose execution requests information about input filesand parameters pertinent to the analysis being performed.Frequently the facilities provided by the command files are inadequate, in which case Magicshould be used interactively. This takes the form of commands to Jam and use of the mouse.Commands applicable to all analyses are provided later in this document, and commandsrelevant to specific analyses are contained in the Appendices.ЪНЇОfЯuНGОНЇОbsТt Н2О^РuТ╠П4Т╡П&Н2О]nТфТгП@Н2О[ЙТ©ПTТюН2ОZfТ▒ПUТ▓Н2ОXБТрП&ТсП3Н2ОW^Т╪П&ТҐП5Н2ОUзТ-ПTТ.Н2ОTVТ╒ТёПPН2ОRрТНЇОOїН2ОL{Т▒Т▓П?Н2ОJВТ╛П%ТґП;Н2ОIsТ╒П.ТёП+Н2ОGОТ НЇОCstН2О?ЯuТ░Т▒П?Н2О>mТ▀П*Т▄П4Н2О<ИТПRН2О9ҐТ▌ПTТ▐Н2О89Т┐П\Н2О6╣Т╘ПOТ╙Н2О51Т┘ПVТ├Н2О3ґТП0НЇО0┌Н2О-VТ∙П/Т√П,Н2О+рТП$НЇО(їН2О%|Т┐ПOТ└Н2О#ЬТ═П%Т║П6Н2О"sТ╦ПBТ╧Н2О ОТПGН2ОдТ╨П!Т╩П:Н2О@Т│Т┌ПYН2О╪Т┘ Т├ПWН2О8ТП9Н2ОТ╟П)Т╠П2Н2О┬Т≈ПAТ≤Н2ОТЮП9ТАН2О─ТП>ЪtЇ9Magic>Magic*.cmwhere the * stands for the name of the analysis required, e.g.[Indigo]Magic>MagicDRC.cmwill get and initialize Magic and the Design Rule Checking module. Also on that directory is afile:[Indigo]Magic>UpdateMagic.cmthat will update your disk for the entire system, including getting the system for the first time.Periodic execution of this command file is recommended. There is no need to updateUpdateMagic.cm itself as it is expected to never change.3. COMMANDSCommand file usage of Magic for any one analysis involves using one of two .do files - for CIFand Icarus input. For example, CIFtoDRC.do and ICtoDRC.do are used for design rulechecking. The .do files for the various analyses require different parameters. They aredocumented in the Appendices.3.1 Interactive usageThe interactive use of Magic usually proceeds as follows:1.read one or more layouts into the Magic database;2.use viewing commands to see what is there;3.select an analysis module;4.set up precise view and parameters for selected analysis;5.invoke the analysis;6.repeat from 3.The reason for having selection of an analysis module separate from its invocation is that certainanalysis modules affect the way in which the display is managed. For example, the Pressmodule forces the viewing region to be the shape of the array of pages requested. Also, certainstate can be set within a module only while it is selected.The available commands are from three sources - commands directed to JaM, primitive Magiccommands, and JaM procedures. While users need not be concerned with these distinctions, itmay be helpful to note that online documentation of most commands that are implemented asJaM procedures can be obtained using the JaM utility command "?", e.g. (reset)?.The commands are presented here in two categories: those common to all analyses, and thosespecific to particular analyses. The latter are documented in the Appendices. Screen output isimplemented as an analysis, but it is treated specially in that the system always includes it.ЪНЇОfЯuНGОНЇОbТН2О^РПLН░О[гН2ОX°П>Н░ОUpН2ОREТ┤П]Т┬Н2ОPаН░ОM∙Н2ОJjТ∙Т√ПHН2ОHФТРП'ТСП,Н2ОGbТП8НЇОB▐stН2О?duТ┘ПVТ├Н2О=ЮТыП>ТзН2О<\ТГТХПGН2О:ьТНЇО7╛Н2О4│П9НґО1UН(П1НґО/ўН(П*НґО.Н(НґО,_Н(П9НґО*╦Н(НґО)Н( Н2О%ЕТ─ПUТ│Н2О$aТкПXН2О"щТ┤ПRТ┬ Н2О!YТП;Н2О.Т П%Т⌡П4Н2О╙Т░П3Т▒П)Н2О&Т≤ПFТ≥Н2О╒ТПPН2ОvТ═Т║ПJН2ОРТ▒Т▓ПJН2ОnТюП^xЇ' readcifRead the layout in CIF format from the indicated file, and add it to the layout currentlystored.

Viewing iscontrolled by a combination of the mouse and keyboard. The mouse is used for zooming,scrolling, and changing the window. Keyboard commands are used to change modes.Zoom: Red mouse button. Define a rectangle by pressing down at one corner, moving themouse to the other corner, then letting the button up. While the button is down therectangle is indicated by video reversing its contents. Zooming up or down is determinedby the relative positions of the two corners of the rectangle.If the second corner is up and to the right of the first then the image is expanded so thatthe contents of the rectangle just fit into the current viewing area. This is a best fit - theimage is never differentially scaled.If the second corner is down and to the left of the first then the image is contracted so thatthe contents of the current viewing area just fit into the rectangle.Scroll: Yellow mouse button. Press down at the source position, move the mouse to thedestination position, then let the button up. The image is then scrolled so that whateverwas at the source position now appears at the destination position.Window: Blue mouse button. The viewing region can be redefined as a rectangle in much thesame way as for zooming, except using the Blue button. The relative positions of the twocorners has no effect.drawUsage: drawRedraw the image. Drawing can be interrupted using the JaM break key (rightshift-swat).See also the command outline for dealing with complex files.outlineUsage: outlineSet a mode such that only the outline of the current layout is drawn. This is to allowmanipulations of the image without having to wait for all the detail to be drawn.unoutlineUsage: unoutlineUnset outline mode.fitUsage: fitThe image is scaled and positioned so that the entire layout just fills the current viewingregion.clipfitUsage: clipfitThe clipping region is adjusted to just surround the layout.atoriginUsage: atoriginНЇОfЯuНGОН2ОbsНґО` uТП+sНґО_uП@Н(О[ЙwНЇОX©u Н2ОU■ТҐПLТЎН2ОTТ©ПVН2ОR▀ТПPН2ОO`suТЇТ╦П?НґОMэТхТиПBНґОLXТ²ПFТ·НґОJтТП>Н═ОG╗Т≥П+Т П0Н═ОF$Т°П?Т²Н═ОD═ТП%Н═ОAuТ┬ПKТ┴Н═О?ЯТПEН2О<фsuТп ТяПBНґО;AТ╗П"Т╘П8НґО9ҐТПCН2О6▓suТ⌠Т■П?НґО5Т╒ ТёПMНґО3┼ТН2О0_sНґО.зusНґО-VuТ≥П;Т НґО+рТxuН2О(їsНґО'#usНґО%÷uТ╦П%Т╧П2НґО$ТПQН2О ОsНґОkusНґОГuН2О╪sНґО8usНґОЄuТ╙ПKТ╚НґО0Н2ОsНґО─uТsНґОЭuП<Н2ОяsНґОMus└Ї;l]Magic7The image is positioned so that the bottom left corner of the layout is at the bottom leftcorner of the current viewing region.scrolltoUsage: scrolltoThe image is scrolled to bring the point to the center of the current viewing region. and are in CIF units (hundredths of a micron).invisUsage: invisThe given layer name is made invisible for the purposes of both subsequent drawing on thescreen, and subsequent analysis by any analysis module. The name is a string conformingto the CIF conventions. e.g.(NM) inviswill suppress the metal layer.visUsage: visThis is the inverse of invis. The given layer name is made visible for the purposes of bothsubsequent drawing on the screen, and subsequent analysis by any analysis module. Thename is a string conforming to the CIF conventions. e.g.(NM) viswill restore the metal layer to visibility.showUsage: showThis command is used to examine a log file, showing each text message in the typescriptwindow while showing the corresponding geometry in the viewing region. e.g.(analysis.log) showFor each entry in the file analysis.log the text portion will be output to the typescriptwindow, and the corresponding geometry scrolled to the center of the viewing region, usingthe currently set up scale. It is therefore advisable to set up a suitable scale using themouse before using show. After each line the prompt More? will appear, to which youshould type to see the next entry, or n to suspend show. Note that no othercommand, nor the mouse, can be used while show is in control. See also the commandmore.The command show is available for viewing any analysis log that conforms to the followingsyntax requirements. Each entry should be a line of text starting with two decimalnumbers, each terminated with at least one space, which give the coordinates of the featurein CIF coordinates. The remainder of the line should contain the associated message.moreUsage: moreResume showing entries in a log after suspending a show command.boundboxUsage: boundbox => Return on the JaM stack the bounding box of the current layout.НЇОfЯuНGОНґОbТ╔П#ТіП7НґО` ТП%Н2О]nsНґО[Йu sНґОZfuТ▀П"Т▄П:НґОXБТП6Н2ОUЇsНґОT3usНґОR╞uТ┘П.Т├П+НґОQ+Т≥ПAТ НґОOїТН(ОL{w НґОIPuН2ОF$sНґОD═usНґОCuТ█ПGТ▌НґОA≤Т╗П9Т╘НґО@ТП9Н(О<ИwНґО9ҐuП+Н2О5ЎsНґО4:usНґО2ІuТїТ╗ПKНґО12ТПLН(О.wНґО*шuТйП0ТкП)НґО)WТ┴ Т┼ПOНґО'сТҐП[НґО&OТ╣П5xuТІНґО$кТєxuТ╔ xuП%НґО#GТ╛П#ТґП0НґО!цxuНґО≤Т▌xuП;Т▐ НґОТЙПBТКНґО░Т█П7Т▌П$НґОТнП"ТоП3Н2ОsНґО┬uТsНґОuП3xuН2ОыsНґОUusuНґОяП?└Ї┼9Я[│Magic83.5 Selection of Analysis ModuleAn analysis module is selected as current by a command of the form The are dependent on the being selected.

Color Press ModuleThe Color Press module produces color press files of the layout. The layout is split into separatepages that are generated on separate files. The image on each page overlaps its neighbor by 1/4",to allow for inaccuracies in trimming the paper. Each page is identified with page number, filename, and user name.A1.1 InitializationFirst get and initialize Magic for Press output as described under 2.3 "Where to find Magic",either by retrieving and executing[Indigo]DStar>MagicPress.cmor by getting everything from[Indigo]DStar>UpdateMagic.cmA1.2 Command file usageTwo .do files are provided for converting a single layout to Color Press output, one for CIFinput and one for Icarus:CIFtoPress.doICtoPress.doThese can be run using Do.run and answering the prompts for parameters, or by providingparameters on the command line in the form:Do CIFtoPress Four optional parameters are supported, to give the indices of the first and last pages to begenerated. These can be given only from the command line which then takes the form:Do CIFtoPress ^ <1st page row><1st page column>This will fit the entire layout to the requested, and will generatethe pages in row order between <1st page row><1st page column> and , inclusive, in row order. Any of the parameters can be out of range in which case themaximum or minimum permissible parameter value is used. Each page is output to a separatepress file, the names being of the form: filename-i-j.press, where i and j are the row andcolumn numbers of the page. If the filename starts with a fileserver name the pages are writtento the file server as they are generated. This minimizes the need for local file space for thepress files. Be warned that you must be logged in to the executive with a valid password beforeusing this option.A1.3 Interactive usageInteractive use of Magic for generating Press output is useful for experimenting with the fit ofthe layout to a given set of pages, for extracting a piece of the layout for printing, and forsuperimposing several layouts for printing.pressUsage: pressSelect the Press module for subsequent output.

Each time press is selected, amaximal-size array of pages of the specified aspect ratio is laid out within the existingclipping region, and then the clipping region is shrunk to conform to the aspect ratio of thenew page array. Thus, reselecting press with a different aspect ratio will cause the clippingregion to shrink. In order to scale the drawing to fit within the new, smaller clippingregion, use the fit command. If repeated use of press leads to an awkwardly smallclipping region, it's size may be reset using the blue mouse bug Window command, asdescribed in Section 3.4 Viewing.outputUsage:<1st page row><1st page column> outputOutput the current contents of the viewing area to the press module to generate the pagesin row order between those indicated in the first four parameters, inclusive.

Circuit Extractor ModuleThe Circuit Extractor Module generates a switch level circuit representation of the layout. Itunderstands only NMOS technology, including buried contacts, but is not sensitive to design rules.The extractor generates two files - a .sim file for subsequent electrical rules checking [erc] and/orsimulation [SimMOS], and a .nodes file that is a legitimate cif file containing all names with theirpositions, including names generated for unnamed nodes. This file can subsequently be read backin and combined with the original layout for viewing or plotting of the layout with node numbers.Names in the input layout file are interpreted. Each name is taken to name the point thatdetermines the position of the name. Each of these points should be inside a unique layer ofgeometry, and it is taken to name the node of which that piece of geometry is a part. Names overno geometry are reported. Names of more than one node are also reported, and the name isassigned to one of the nodes, generated names being used for the other nodes. A node can benamed more than once. However, if the names differ a warning is output and one of the names isabandoned.Note that the names Vdd and Gnd are required by subsequent circuit analysis tools.

One file is generated: filename.erclog, which containsa log of all electrical rule violations. Summary information on the electrical characteristicsis output to the typescript window. e.g.(chip) 3.5 4.5 ercwill generate chip.erclog and display a summary in the typescript window.A convenient way of viewing the results is to use the show and more commands describedin Section 3.4. Do this by showing the .erclog file.A3.4 ExplanationThe summary messages that appear in the typescript window arenodes, transistors, pullups : %d %d %dpullups and non-inverting superbuffers : %d %dinverting superbuffers and unknowns : %d %dSum of 1/Z's for all pullups : %d(syntax error : %s)where %d is a decimal number. The decimal numbers are just counts of the designated types ofcomponents found in the circuit by the electrical rules checker. The sum of the 1/Z's can beused to estimate maximum power dissipation of the circuit by multiplying by the appropriatenumber for the process you are using (approximately .6 milliwatts per 1/Z for NSIL-II). Thesyntax error message shouldn't appear unless your files are confused.НЇОfЯuНG?НЇОbsТП$НюО^РuТ°ПNТ²НюО]nТПSН;ОZCП;xuНюОWТўxuxuП1Т╞НЇОSЛТН2ОPаТхПLТиН2ОO=ТП*Н░ОLП#Н2ОHФН░ОE╩НЇОB▐Н2О?dТ⌠ПAТ■Н2О=ЮТ÷П\Н2О<\Н2О90sНґО7╛uНёТsНґО6(uТП7ТНґО4єТР ТСПEНґО3 Т├Т┤П@НґО1°Т≥П@Т НґО0ТП(Н(О,МwНґО)аuПIНґО&√Т≥Т П#xuxuНґО%ТxuНЇО!ФН2О╩П=НґО░wП&НґОП.НґО┤П.НґОП!НґОН2ОпuТ┌wuП"Т┐П3Н2ОLТ²ПVТ·Н2О хТ╘П[Н2ОDТ²ПEТ·Н2О юwТuП9╙Ї y=ч]▓УMagic17The messages that appear in the .erclog file are listed below in alphabetical order with shortexplanations of what they might mean. %n indicates a node name in the message.Assuming lightning arrested node is an Input : %nA lightning arrestor is a transistor whose gate and drain are Gnd.
