Class LENetlister1

java.lang.Object

com.sun.electric.database.hierarchy.HierarchyEnumerator.Visitor

com.sun.electric.tool.logicaleffort.LENetlister

com.sun.electric.tool.logicaleffort.LENetlister1

public class LENetlister1
extends LENetlister

Creates a logical effort netlist to be sized by LESizer. This is so the LESizer is independent of Electric's Database, and can match George Chen's C++ version being developed for PNP.
