TMC-20007: Unregistered Paths Between User-Partitions

Found unregistered paths between design partitions in the project. A combinational timing path between two partitions is susceptible to timing closure challenges. Inter-partition timing paths depend upon clock skew between launch and latch registers, both of which are inside different partitions. This condition complicates timing closure.

Recommendation

Ensure that inter-partition paths are registered at the output of the driving partition.
