Can any one let me know if there is an option or command in the tool which can generate all the cells in between two talking flops so that i can upsize,downsize only those set of cells or replace HVT with RVT or viceversa.
you have to report timing using the option -from launch flop -to capture flop then it will report all the datapath cells in the report.
Basically you need to change cells based on the timing analysis
In reply to mohan kumar:
We do change cells based on timing,but the reason why I want to replace them is to make them a strong drivers with steeper transitions(to prevent or minimise the effect of Xtalk)
NOTE: we can do this only when power is not a major concern.
