Assura LVS shows "n_psub_StampErrorMult" error

AdeelAnwar

I'm designing a PA layout in Virtuoso 6.1.8.-64b

My circuit contains mim capacitors, rphpoly_rf resistor along with 2V rf_NMOS and 2 Sporal_std_mu_x_20k. I get these errors when I place a second Inductor. when I ran LVS, it showed these three errors:

> n_psub_StampErrorMult

>psub_term_StampErrorMult

>psub_StampErrorMult

I don't have a clear idea of what these errors mean. I tried to google it but found no helpful information. I checked a couple of times in my layout to find any short or floating body. I do not see any. Could you explain the error and possible ways to solve this?

Thank you

    Given the name of the errors, it sounds as if there are more than one metal connection into the substrate (to different nodes), but this is just a guess. The actual errors will be dependent upon the rule deck from the foundry - you should check the PDK/rule deck documentation and if it's unclear, contact the foundry support as this will be specific to whatever technology you're using.
