TMC-20500: Hierarchical Tree Duplication was Shallower than Possible
Description
Hierarchical tree duplication can be limited by a variety of issues, usually related to issues with pipelining of registers upstream of the tail register that feeds the hierarchy tree.
For more on Hierarchical Duplication and the DUPLICATE_HIERARCHY_DEPTH assignment, refer to Hierarchical Proximity in the Register Duplication section of Intel Quartus Prime Pro Edition User Guide: Design Optimization .
Recommendation
Address the issue limiting the duplication, or increase the number of pipeline stages preceding the high fan-out tail.
Severity
Low
