how to accelerate placement in large design?

archive

When doing floorplan in a large design, We partition top and estimate whether floorplan is satisfied or not. So place and route become necessary step. My problem is placement is so slow because of many gates in partition. how to solve it ?

  • 3x elvis. my design is about 20 million gates and 11 partitions. Does encounter only place instance relative to port of partition, not more placement work in partition. cluster place sounds interesting, could you tell me more about it or some documents.
