Constructor Detail

DelayEstimatorBase

public DelayEstimatorBase(Device device,
                          T ictInfo,
                          boolean useUTurnNodes,
                          int verbose)

Constructor from a device. Package scope to disable creating DelayEstimatorBase by a user. Create one using DelayEstimatorBuilder instead.

Parameters:

device - target device.

Method Detail

isLong

public static boolean isLong(Node node)

Check if the node is a long node or not

Parameters:

node - the node to be checked

Returns:

true if the node is a long node

getExtraDelay

public static short getExtraDelay(Node child,
                                  boolean longParent)

Return an extra delay if both parent and child are long node.

Parameters:

child - a child node

longParent - an indicator if the parent is a long node

Returns:

the extra delay if any

getDelayOf

public short getDelayOf(Node exitNode)

Get delay of the node group of the given exit node.

Parameters:

exitNode - the exit node of the node group

Returns:

delay in ps
