Working on Hierarchical UPF flow

Working on hierarchical UPF flows these days, its quite interesting to observe how tools optimize PST hierarchically and also on how to constrain/write UPF for lower level blocks.



There are quite a few challenges in terms of UPF with respect to


(a) Location of special cells such as LS/ISO/ELS…etc

(b) Depending on whether location is parent/self, physical implementation is going to be different for each of these strategies

(c) How to assemble blocks at the top level and finally analyze the power intent.
