PPR 5.0 will not guide correctly with a pre-XACT 5.0 lca file


Record #466

Problem Title:
PPR 5.0 will not guide correctly with a pre-XACT 5.0 lca file


Problem Description:



Solution 1:




PROGRAM: PPR	

VERSION: 5.0

PLATFORM(s): All

SHORT DESCRIPTION:

PPR 5.0 can't guide from any lca file created by the pre-XACT 5.0 tools.

ERROR MESSAGE: N/A

LONG DESCRIPTION: 	

PROBLEM:

User has an lca file created with the pre-XACT 5.0 toolset (either w/PPR or
EDITLCA), and he can't use it as a guide file.	

CAUSE: 		

To support guide, certain information has to be entered into the lca file
during the place and route process. The older tools did not put this
information in, and there is not way to 'go back' and put it in.


SOLUTION: 	

Re-run the design through PPR 5.0 w/o using a guide file, then use this
lca file as the starting point.
