Thanks for the review! You are correct that this is a bug. I had planned once round_rate is removed from the clk core to post a series to remove divider_round_rate() and divider_ro_round_rate() (plus the _parent functions) since they call the corresponding determine_rate functions. I'll bump that up on my todo list this week. Brian
