Pin Name Problem in Assura

[Raymond]

Dear all,

I am using Assura to perform DRC. There is a problem i cannot solve.
In layout, i have used "MET1 (pn)" and named by "Vdd!" for the substrate
contact of PMOS,
but there is still a DRC error of "HOT_NTUB", that is the separation of DIFF
to NTUB.
Normally, the distance should be Vdd's NTUB to DIFF = 1.2,
but DRC think it is NON-Vdd's NTUB to DIFF= 2.6.
Could anyone tell me how to let the Assura know it is Vdd region?

THANKS!

Best Regards,
Raymond

Raymond,

This question is specific to the design-kit, and not related
to Cadence Assura software.
I just sent you an E-mail with the solution.

Please note that your University has signed a Confidentiality
