Problem Title:
FLOORPLANNER v6.0/5.2: PPR May Fail Due to Invalid Floorplanner
Placement



Problem Description:
PROBLEM:  PPR fails with placement errors.


Solution 1:




PROGRAM: Floorplanner

VERSION: 6.0

PLATFORM: All

CAUSE:

The Floorplanner does not check for all the placement rules; consequently,
PPR may fail on a design due to an invalid placement that was not caught by the

Check Floorplan command.

SOLUTION:

Check the ppr.log file and/or onscreen messages to determine the invalid
placement that the Check Floorplan command did not indicate.  Then use the
Floorplanner to correct the invalid placement.
