getDelayEstimator

public DelayEstimatorBase<InterconnectInfo> getDelayEstimator()

Gets the delay estimator that this graph computes its node delays with.

Returns:

That delay estimator, or null since this graph is not timing driven.

isVersalLagOutRoutethru

public boolean isVersalLagOutRoutethru(Node parent,

Determine if the given nodes represent a SLICE routethru from an input site pin dedicated for SLLs to the [A-H]Q or [A-H]Q2 output.

Parameters:

parent - Start node of PIP

child - End node of PIP

Returns:

True if routethru
