Class MOSSIM

java.lang.Object

com.sun.electric.tool.io.output.Output

com.sun.electric.tool.io.output.Topology

com.sun.electric.tool.io.output.MOSSIM

public class MOSSIM
extends Topology

This is the netlister for MOSSIM. A circuit can be augmented in a number of ways for MOSSIM output: The variable "SIM_mossim_strength" may be placed on any node or arc. On transistor nodes, it specifies the strength field to use for that transistor declaration. On arcs, it specifies the strength field to use for that network node (only works for internal nodes of a cell).
