Foundation Simulation seems to hang, or takes a long time before showing the waveform


Record #3120

Product Family: Software

Product Line: Aldec

Product Part: Foundation Logic Simulator

Product Version: 1.3

Problem Title:
Foundation Simulation seems to hang, or takes a long time before showing the waveform


Problem Description:
Urgency: Standard

General Description:

Doing a Foundation Simulation when I run a command file or hit
long step, the simulation seems to hang, or takes a long time
before coming back and showing the waveforms.


Solution 1:

If the command file or if the long step is a long time period the
simulation may appear to hang, or takes a long time.

One way of cutting the runtime down is by lowering the Simulation
Precision, if feasible, to the simulation.

To do this:

Options->Preferences

and in the lower left hand corner is "Simulation Precision" box
that has a pulldown to change the value.
