Figure Causing Multiple Stamped Connections

[dsj_guilin]

Hi all,

I am new with the layout. I finished a tutorial of layouting an inverter. Now I am doing a layout for a very simple circuit (1*NMOS + 1*cap). I got 2 errors from the DRC (with switch of "no_coverage ") which are:
Figure Causing Multiple Stamped Connections.
Figure Having Multiple Stamped Connections.
Could any one help me to solve them?
Figures of schematic and layout are attached.

Many thanks.

"Multiple Stamped Connections" means that you have multiple nets connecting to the bulk. In your case, I believe, the nmos transistor does not have a bulk connection.

Thank you Joannes. Problem solved.
