3.1i Virtex-E MAP - Crash after "Running Directed Packing..." due to incorrect MUXF5 trimming.

Description

Keywords: crash, Running Directed Packing, F5MUX, MUXF5

Urgency: Standard

Problem Description:
A case has been seen where a MAP crash was caused by the
incorrect trimming of a MUXF5. The MUXF5 output signal is
trimmed because it feeds the I1 input of a MUXF6 whose select
is tied to ground (MUXF6 is a route-thru) and this makes the I1
input redundant. Thus, a MUXF5 with no output is fed to the
packer, and this causes the packer core dump.

(This MAP crash reproduces in Ds1 and DQA on both PC and Solaris.)

Solution

This problem is fixed in the latest 3.1i Service Pack available at:
