Hi,
I am going to make a 3 bit ring counter using 3 7474 D-FFs. It is my habit to first simulate and then actually design, the PSpice capture simulation is as,

Now what I want to ask ?
How to generate the P2 signal which is LOW for 2ms and then HIGH (for ever till the supply is on). It is like u(t-2ms) where u(t) is unit step function (=1 for t>0 and =0 for t<0)
Or is there any other way to load 100 in my counter automatically just after turning on my counter.
Using a 555 timer I have to give trigger but I want P2 automatically i.e., as soon as I turn on the main supply the counter starts running 100 should be loaded automatically.
Please reply soon I am in a great need of it.
