Logic Gate Propagation Delay & Max Clock Frequency Calculator
Calculate the maximum clock frequency of a digital circuit from gate propagation delay, setup time, and pipeline stages.
Your inputs
Change any value to update the result instantly.
Maximum clock frequency
434.7826 MHz
Minimum clock period
2.3 ns
Critical path delay
2 ns
Setup + skew overhead
0.3 ns
Reducing gates in the critical path or pipelining the design are the usual ways to push maximum clock frequency higher.
Formula and working
Tclk(min) = (gates per stage × propagation delay per gate) + setup time + clock skew; Fmax = 1 ÷ Tclk(min)
- 1
Collect the inputs
Logic gates in the critical path per stage = 4; Propagation delay per gate (ns) = 0.5; Flip-flop setup time (ns) = 0.2; Clock skew / jitter allowance (ns) = 0.1
- 2
Apply the formula
Tclk(min) = (gates per stage × propagation delay per gate) + setup time + clock skew; Fmax = 1 ÷ Tclk(min)
- 3
Result
Maximum clock frequency = 434.7826 MHz
