655 Ring oscillator with counter

655 : Ring oscillator with counter

Design render

How it works

A ring oscillator with a 64-bit counter that counts the number of oscillations. The counter is connected to pins ou_out, and is shifted by the cnt_shift input. The counter is reset when cnt_reset is high, and stops when cnt_stop is high.

How to test

Set inputs 0 to 5 to the desired counter shift value, and observe the counter on outputs 0 to 7.
