11.1 PlanAhead - "ERROR: [HD-DB 2]Part: xc4vlx100ff1148-10 has no WASSO data for IOStd LVDS_25"

Description

Keywords: SSO, SSN, Ground bounce

When I attempt to run WASSO Analysis for a design which has LVDS_25 in Bank 7 of the Virtex-4 LX100 in the ff1148 package, the following message appears:

"ERROR: [HD-DB 2]Part: xc4vlx100ff1148-10 has no WASSO data for IOStd LVDS_25"

How do I run SSO Analysis for this design?



Solution

Since LVDS_25 has no SSO limits, you can safely remove these location constraints while running WASSO Analysis.

This issue will be fixed in a future release of PlanAhead.
