What factors do min, typ and max values of a IOPATH delay depend on.
What is it if only one operating condition is specified while generating SDF ?
Is it the min max value that delay can take considering various load capacitance's and input slew values? Does it consider the effects of process variations as well ?
if you load three std-cell corners + three RC extraction corners you should have three differents values in your SDF.
And in opposite way, if you load only one corner + one RC, and define that "set_operating_conditions -analysis_type single ...", the min & max values will be identical.
if you used "set_operating_conditions -analysis_type on_chip_variation...", the min and max will differ.
