4.2i Virtex-II Speed files/NGDANNO - A registered multiplier does not have GSR delay for simulation

Description

Keywords: NGDAnno, ModelSim, simulation, multiplier, GSR

Urgency: Standard

General Description:
There is no delay from the GSR signal to the registered multiplier reset. Is this correct?

Solution

The speed files are missing a delay for this number. This is not likely to cause any simulation issues (although there is a small chance that it may).

This problem is completely fixed with a correct delay number in the latest 4.2i Service Pack, available at:

The first service pack containing the fix is 4.2i Service Pack 2.
