Primitive: Global Clock Buffer driven by fabric interconnect
- PRIMITIVE_GROUP: CLOCK
- PRIMITIVE_SUBGROUP: BUFFER
Introduction
This design element is a high-fanout buffer that connects high fanout signals such as sets/resets and clock enables from the fabric interconnect to the global routing resources.
