Product Family: Software

Product Line: Aldec

Product Part: Foundation Logic Simulator

Product Version: 1.5i

Problem Title:
F1.5i Simulator, Virtex: Cannot simulate CLKDLL component in a Timing Simulation.


Problem Description:
Urgency: Standard

General Description:
Simulating CLKDLL in Foundation Simulator 1.5i does not produce any
clock frequency, just a constant value.


Solution 1:

This problem has been corrected for all outputs of the CLKDLL except
the DIVIDE output. This will be resolved in a future software release.

F1.5i Service Pack 2 fixes the other outputs and is available at:

Note: This software update only enable timing simulation of the CLKDLL.
Functional simulation will not work.
