The following error is reported during MAP:
How can I resolve this issue?
This error indicates that the component driven by the Regional Clock Net (BUFR output) is placed in a clock region that cannot be reached by this clock net.
To resolve this problem, try the following:
1. Try different MAP/PAR options.
2. Evaluate if the BUFRs in certain clock regions are not sufficient for the design leading to the BUFR being placed far away from the source/destination.
3. Apply an area_group constraint to the load components of the regional clock net.
This will limit these components to being placed in the clock regions which the clock net can reach.
(Refer to the target device user guide for information on BUFR structure.)
4. This issue can also happened in MIG/MPMC designs if you assign/modify the pin locations without MIG's update and verify.
Going back through the entire MIG flow can solve this problem.
