M1.5i PAR: ERROR:xvkap:50 - Design conataines net <netname> driven by TBUFs that are constrained to different rows


Record #5582

Product Family: Software

Product Line: FPGA Implementation

Product Part: par

Product Version: 1.5i

Problem Title:
M1.5i PAR: ERROR:xvkap:50 - Design conataines net <netname> driven by TBUFs that are
constrained to different rows



Problem Description:
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 1:

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.
