16 years agogate timing spec on 40nm FPGA
Hi everybody, Does anyone know what is the delay time of a "not" gate in 40nm technology? And does anyone know what is the minimum pulse width for clock input in one FlipFlop or in one D-latc...

16 years agoHi,
I'm afraid I don't have the actual figures for you but the specs you want are dependent on quite a few variables. Firstly if you are using measuring these values in a design they may change depending on where where the logic is placed on the FPGA. e.g. setup and hold time will vary by the difference of how far the signals have to travel from where they are asserted. Temperature and process variation as well as the speed grade of the FPGA will have an effect so there is probably no one real answer. Although I'm sure people involved with Altera could probably give you a better idea. Just my 2 cents!
