Hi @Tim Edwards, for the ULP comparator, I just wanted to confirm that it was ok to use the enable pin (ena) as clock to the comparator? The comparator we were implementing (from here) is clocked, and the pinout spec has a digital domain enable pin — I can invert it locally to have both CLK and CLKb, or can request a name change for the ena to be clk…what would be preferable?

I would prefer a separate enable and clock, because when disabled it needs to be completely powered down. Probably I should have just assumed that it would be clocked and add the clock to the pin list. You will want to generate CLKb internally, especially to control its timing with respect to CLK.
