Hi,
I have a design which is constrained by aocv derates from foundry libraries as well as flat derates for added pessimism. I need to determine physical skew and ocv skew component separately for all the sinks created by the default skew balanced clock tree synthesis so that I can come up with a better clock tree plan. I am using Cadence Innovus as my PnR tool and as of now not being able to find any command which helps me to distinguish between the physical skew and ocv skew components of the total skew that is being reported.
Please let me know if there is any particular command to determine the components or rather if there is any generic well defined way to get the values .
Thank you !!
