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?
解决方案
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.
