Some inverters will have asymmetrical rise/fall times, but most will be symmetrical. You need to give a part number.Yes any particular inverter.
Do you really mean 10F? That's a huge capacitance for an inverter to drive.Loaded with 10f cap
It's more related to the relative drive strengths of the PMOS and NMOS transistor. In older process technologies, NMOS drive was 1.5-2X that of PMOS, so PMOS devices were made larger to compensate for that. In later process generations, drive strength became more equal. I can't recall when the transition took place, but it depends on the process technology; and each company has different recipes.I want to know the physics why are not equal the rise times...I think this effect connected with the change of input capacitance pmos transistor...I take 32nm transistors from SAED library
