I have one method of using a counter. The formula for calculating the counter is ( Actual Frequency / required frequency)
use that as the set point for your counter and make use of this code(This IS for 26MHz from 100MHz clock, so the Count value WilL be(100m/26M = 3.)
- if (clock = '1' and clock'event ) then
- if ( count /= 4)
- count := count + 1 ;
- clock_out := clock_out ;
- else
- count := 0 ;
- clock_out := not clock_out ;
- end if;
- end if ;
so for 13MHz the count value will be 7
