Method Detail

findEquivalentNet

public HierarchyEnumerator.NetNameProxy findEquivalentNet(VarContext vc,
                                                          Network net)

Given a Network in one design, return the matching network in the other design.

Parameters:

vc - the VarContext specifying the instance path of the network

net - the network in one design

Returns:

the matching network in the other design

findEquivalentNetShortingResistors

public HierarchyEnumerator.NetNameProxy findEquivalentNetShortingResistors(VarContext vc,
                                                                           Network net)

Given a Network in one design, return the matching network in the other design. Treat resistors as short circuits.

Parameters:

vc - the VarContext specifying the instance path of the network

net - the network in one design

Returns:

the matching network in the other design

findEquivalentNode

public HierarchyEnumerator.NodableNameProxy findEquivalentNode(VarContext vc,
                                                               Nodable node)

Given a Nodable in one design, return the matching Nodable in the other design.

Parameters:

vc - the VarContext specifying the instance path of the Nodable

node - the Nodable in one design

Returns:

the matching Nodable in the other design

regressionTest

public int regressionTest(Cell cell0,
                          Cell cell1)

Perform a sanity check of the equivalence tables. This method is used by the NCC regressions.

Parameters:

cell0 - first Cell. this is used for the status message

cell1 - second Cell. this is used for the status message

clearCache

public void clearCache()

To reduce storage requirements, release cached information when you are done using this Equivalence table.
