I was designing a system, and the customer wanted to operate it on 10MHz.
There was a 10 Millisecond counter in that design, so I applied a 17 bit counter that gives a tick every 10 milliseconds based on this frequency. The code was like that:
Is there any method that no matter what sys_clk is, we are always count 10ms? I thought about parameterization, but how cant imagion that. Can some body help in this regards? For now, lets assume that frequency is 1 to 10MHz.
