Hi,

what exactly happens on the IO in this case?
Do you need a bug fix?

Cheers

I tried to use this module with parameters initialized at reset state without wishbone part with constant frequency/period.
I had completely different behavior with and without g_selectable_duty_cycle parameter. When g_selectable_duty_cycle was false I have seen no output.
After a moment of reflection I thing there is mistake in both p_secondary_counter processes at reset condition. The per_hi_i input value should be assigned to per_count_lo register.

We'll check this.

Thanks for your report.

reproducing, understanding and fixing would be a major effort -> postponed
