A1.4/F1.4 PAR - PAR crashed during placement of xc40125xv when using Leveraged Guide.


Keywords : core, dump, guide, leverage.

Urgency : Standard

General Description:
PAR crashed with application error when guided with leverage
mode in this design.

This issue will not be patched in M1.4. Leveraged guide is

The workaround in M1.4 is to use 'exact' guide mode.
