AR# 4959
A1.5/F1.5 Map caused an invalid page fault in libbasut.dll
Description
Keywords: Map, fatal error, libbasut.dll
Urgency: Standard
General Description: Design implemented in M1.5p (service pack) gets crashes in Map.
Solution
This problem will be fixed in the first service pack after M1.5i. The error is caused by OBUFTs that are reduced to constants, because both the input and the enable signals are tied to GND. Workarounds until the release of the service pack are:
1) Eliminate the redundancy in the circuit; one could replace the OBUFTs with OBUFs tied to GND.
2) Place a KEEP attribute on the net tied to ground to keep map from trying to merge the constant all the way forward to the pad.
