Simulating digital clock in multisim

I am trying to simulate a digital clock for counting 0-60 seconds using two seven seg displays two 7447 two 7493 and two clock generators on Multisim
but the problem is i cannot workout the frequency input to be given to the two 7493 ic's connected to the displays through the two 7447 ic's please help.

There really should be only one sign source of 1 pps with a modulo 6 and modulo 10 counter. As the mod 6 counter overflows, the overflow is the count input for the modulo 10 counter.

So, you have two modulo 60 counters for seconds and minutes.

Then comes the tricks for 24 or 12 Hr modes and the AM/PM indicator.
