Basics Channel routing -- The width of a wire is specified as the property $w on the wire; default value is the default for this material Corresponding layoutAtom registered in PWCore $Channel 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. Κ–˜– "Cedar" stylešœ™Jšœ Οmœ1™
