PWCoreRoute provides the types and functions to interface routers into PWCore world.

Channel routing

-- The width of a wire is specified as the property $w on the wire; default value is the default for this material

ChannelData: TYPE = REF ChannelDataRec;

ChannelDataRec: TYPE = RECORD [

inX: BOOL, -- Channel in X is used with an AbutX

extend: BOOL ← FALSE, -- provokes automatic stretch to match the height (resp. width)

extendTopOrRight: BOOL ← TRUE, -- when extension takes place, precise side of the extension

bottomOrLeftWires, topOrRightWires: Wires ← NIL, -- Indicate the order in which those wires appear at the bottom and top. Might be structured, but then only atomic wires are taken into account. All atomic wires must be part of the internal of the cell.

trunkLayer: ROPE, -- from side to side, vertical for a channel in X, "poly", "metal" or "metal2"

branchLayer: ROPE, -- from ct to ct, horizontal for a channel in X

totalWidth: INT ← 0 -- width of channel plus objects, in lambdas; 0 means minimum size

];

Corresponding layoutAtom registered in PWCore $Channel

Channel: PWCore.LayoutProc;

Assumes that parameters (of type ChannelData) are given under the property $ChannelData. Supposes that the cellType is a recordCell with 2 instances, that are considered to be left and right if the channel is in X, bottom or top otherwise.
