Hi folks, Reg. question 1 two threads ago: I’m wondering how the wrapper SDF values are calculated. The delays in the wrapper SDF file, do they only cover the segments on wrapper level? And if so, don’t they depend on the driver and cap in the source macro and the cap in the target macro as well? How is that handled ? Question 3: Assuming SDF format is acceptable, what is the limitation for a flat STA in the Caravel flow so far ? We could generate a flat SDF, right ? The problem is more or less a flat netlist, right ? Just trying to understand the limitations here. Thank you for your answer in advance. Cheers, Tobias
