Problem Title:
xc4000e: dp-ram:xnfprep gives segmentation fault, core dump


Problem Description:
Urgency: Standard

Keywords: xnfprep, XACT 5.2.1, XC4000E

Description
xnfprep v5.2.1 on workstation gives a segmentation fault and a
core dump.
The design contains a dual port RAM RAM16x1D.


Solution 1:

This is a bug in the XACT 5.2.1 software, it will be fixed
in future revisions.
Check to see if the SPO pin is unconnected.
If unconnected, try to connect it somewhere in the design,
where it cannot be optimized away, for example an unused
obuf-opad.
