how to measure eye diagram on a data signal triggered on a self-triggered clk signal

Hi, there.

I’m having some trouble using a clk signal rclk_2 section 1 to trigger another data signal vod_a2b2 section 2… The issue was, if I plot the non-triggered eye of rclk_2, the pos edge zero-crossings will be all jittery section 3, so if I directly use rclk_2 pos edge zero-crossings to trigger vod_a2b2, when the tool overlays all the segmented UIs of vod_a2b2 triggered on all those jittery zero-crossings, the eye would be much messier (assuming I understand the triggering mechanism correctly). What I’m trying to do is to trigger rclk_2 on its own pos edge zero-crossings first, such that all these pos edge zero-crossings are perfectly lined up section 4, and then use this self-triggered rclk_2 to trigger vod_a2b2, such that all the triggering points are not jittery at all compared to the previous case. But I don’t think the tool lets me enter a self-triggered as the triggering signal section 5…

Can someone please help think about how I can possibly tackle this? Could writing new a skill function be a possible solution?

Thanks
