Class NccBottomUp

java.lang.Object
  com.sun.electric.tool.ncc.NccBottomUp

public class NccBottomUp
extends java.lang.Object

Run NCC hierarchically. By default, treat every Cell with both a layout and a schematic view as a hierarchical entity. More specifically, when we are asked to compare a schematic and a layout, we scan both hierarchies to identify cell groups that have one or more cells in the schematic hierarchy AND one or more cells in the schematic hierarchy.

Compare the two designs: cc1 and cc2. Typically, cc1 is the schematic and cc2 is the layout. Note that NCC needs the VarContext in order to evaluate variables such as transistor widths.

Parameters:

cc1 - the root Cell and VarContext of the first design.

cc2 - the root Cell and VarContext of the second design.

passed - an object that remembers which Cell pairs passed NCC the last time the designer ran NCC.

options - all of the NCC options specified by the designer

aborter - an object that NCC queries to tell whether the designer wants to abort the NCC mid run.

Returns:

an object that describes all the mismatches that NCC found
