A1.4/F1.4 Lca2ncd - Re-entrant par of lca2ncd'd design leave partially configured route-thrus behind.

Description


Cases have been seen where re-entrant routing of .ncd's created
by lca2ncd results in DRC errors. PAR will rip-up and re-route a
net that had a route-thru, find an alternate path, but leave the
CLB route-thru partially configured. The problem was found to be
a problem with the lca2ncd conversion and a patch is now available.

Solution

This problem is fixed in the latest M1.4 Core Tools Update
available on the Xilinx Download Area:
