Innovus: Special Route doesn't connect PG rails to PG Rings

Anas2023a95 over 2 years ago

Dear all,

When I use the sRoute command to connect the PG rails, sRoute dosn't connect the rails to the PG ring, instead it stops routing at the core boundary, as shown below:

Is there a way to fix this and make it starts and finishes at the PG rings? The VerifyConnectivity sees those rails as antenna violations.

The command I'm using:

sroute -nets {VDD VSS} -connect {padPin} -padPinTarget {ring} -padPinPortConnect {allPort allGeom}

Kind regards,

Anas

I suppose that with "PG rails" you mean the horizontal stripes of your standard cell rows (the ones that show a DRC violation in your picture)? I'm asking because the command you provided will only connect pad pins to your core ring. If my assumption is right, try using

sroute -nets {VDD VSS} -connect {corePin} -corePinTarget {ring}

Thanks, Domi!

That is exactly what I meant and the solution worked perfectly.
