M1.5i PAR: ERROR:xvkap:50 - Design conataines net <netname> driven by TBUFs that are constrained to different rows
Description
Keywords: 1.5i, par, xvkap, 50, tbuf, constrain, different
Urgency: Standard
General Description: A Virtex design Translates and Maps succesfully. In Place and Route the following error is encountered:
ERROR:xvkap:50 - Design contains net <netname> driven by TBUFs that are constrained to different rows.
Solution
Check to see if 2 TBUFs in the same slice are driving to the same signal. In Virtex, the TBUFs must drive different horizontal long lines. By moving the TBUFs so that only 1 in each slice drives a specific net, PAR will interpret that TBUFs are constrained to the same row and will not report an error.
