4.1i Virtex-II PAR - Error message regarding the source of a TBUF placement problem is misleading


Keywords: TBUF, BUFT, placer, placement, placed, sites

Urgency: Standard

General Description:
When there are too many TBUFs driving the same signal to fit into a single TBUF set, the placer reports the following error:

"Warning: The TBUF component "xyz" cannot be placed.
ERROR: There were not enough sites to place all selected components."

This message is too broad, and it incorrectly implies that the total number of TBUF sites available was inadequate.


This message was improved in 4.1i Service Pack 1, which is available at:
