WebQ 5) What is the maximum clock frequency for the circuit in text Fig. 6.8? For timing purposes assume a gate delay of 2.5 ns for any logic gate, a flip flop setup time of tsu = 1.4 ns, a hold time of th = 1 ns, and a clock-to-output time of tco = 0.8 ns. Please be very sure about your answer! WebReview of Flip Flop Setup and Hold Time I FFs in ASIC libraries have t su’s about 3-10x the t pd of a 1x inverter. I They have t h’s ranging from about negative 1 x the t pd of an inverter to positive 1-2x the t pd of the same inverter. I t su and t h vary strongly with temperature, voltage and process. I t su and t h are functions of the G bw of the FF transistors. WebThese delays are reported for each clock or port for which they are relevant. If there is a case where there are multiple paths for a clock (for example if there are multiplexed clocks), then the maximum delay is reported for the tsu, th, tco, tzx, txz and tpd, and the minimum delay is reported for mintco, mintzx, mintxz and mintpd. how many years between the flood and babel

"WebJul 6, 2013 · You are right but TCO_ext is not = TCO of external device rather it is just another name for it. The issue you raised is because some chips do not give you TCO but rather tSU/tH required at receiving device and then this translates to: TCO(max) = UI - tSU .
