LOGIBLOX, SIMPRIM, 4K - Timing simulation of the counter doesn't work; all outputs are "X."


Keywords: LogiBLOX, counter, X

Urgency: Standard

General Description:
I cannot simulate the LogiBLOX counter after the post route; all the outputs are "X".
Although GSR is toggled at the beginning of a timing simulation, and all
inputs are defined at the beginning of the simulation, the outputs are
always "X" and never change.

Functional simulation is sucessful using the same testbench.


The problem is due to not asserting GSR for a sufficiently long time.
You must assert GSR for at least 100ns.
