I have four power and ground rings around my macro (2 digitals: vccd1, vssd1, and 2 analogs: vdda1, vssa1). The issue is that the power and ground straps of the analog domain in wrapper module (met5) does not connect to my design and only the digital domain connects. Any ideas?

Hi Matt,
You saved my life once in a question about PDNs. Would you mind do me a favor for the 2end time? 😄

11/11/2021, 1:41 PMThanks a lot @User. I changed my design and tried to use only the digital pwr/gnd. I’ll back to you with the screenshot after the deadline (i.e. Nov 12th).
Thanks again.
