Problem Title:
F1.4, F1.5 Timing Simulation: Preserving Hierarchy for Foundation timing simulation
Problem Description:
Urgency: Standard
General Description:
By default, back-annotated netlists are
flattened by the ngd2edif utility which is run by the Flow Engine.
It is possible to generate a netlist that preserves hierarchy.
Solution 1:
* In the Foundation Project manager, select Tools -> Checkpoint
Simulation. (In F1.5, Tools -> Simulation/Verification ->
Checkpoint Gate Simulation Control)
* The Checkpoint Simulation Dialog box will appear.
* Select the desired Version and highlight the .NGA file.
* De-select the Flat Netlist box, and click on Ok. This
re-runs ngd2edif with a switch that preserves hierarchy, and
then launches the simulator upon completion.
