Inverter gpdk180 DRC error. NWELLterm NWVIA : No Stamped Connections

althoff

Hello,

I`m new, studying electronics and this beginning has been though. 

I`ve tried to create a Inverted using gpdk180 technology, but the "NWELLterm NWVIA : No Stamped Connections" keeps popping up every time I make the layout for the PMOS.

I similar problem was occurring with the NMOS part. It showed up the "PSUB SUBVIA : No Stamped Connections." and I handled that with a M1_PIMP connection. The same solution (with M1_Nwell) has not happened for the PMOS in the INVERTER. Everytime I run the DRC it gives me that error and it highlights the PMOS i`ve created. I`ve tried to solve it in different ways, but it seems I dont quite understand what is the NWVIA that the NBurried requires to be connected with the M1.

Any1 have some thoughts?

I`ve put some pics so every1 can see what i`m trying to create.

Tnx,
