Constructor Detail

TimingManager

public TimingManager(Design design)

Default constructor: creates the TimingManager object, which the user needs to create for using our TimingModel, and then it builds the model.

Parameters:

design - RapidWright Design object.

TimingManager

public TimingManager(Design design,
                     boolean doBuild)

Alternate constructor for creating the objects for the TimingModel, but with the choice to not build the model yet.

Parameters:

design - RapidWright Design object.

doBuild - Whether to go ahead and build the model now. For example, a user might not want to build the TimingGraph yet.
