DEVICE statement

Hi

 

Good day, I just want to ask if the below construction of DEVICE statement are correct since I am encountering error on bad device since the device can't be recognized in LVS.

In the rule file we had two versions for resistor, the p-sub and nwell.

 

//P-SUB VERSION

DEVICE  R(res) layer_dev pin_layer_1(pos) pin_layer_2(neg) psub(sub)

 

//NWELL VERSION

DEVICE  R(res) layer_dev pin_layer_1(pos) pin_layer_2(neg) nwell(sub)

 

As you can see, the difference between the two are only the sub. This two are in the rule file since both are used.

 

When I'm using the device with nwell it flagged as bad device but when removed, it cleans.

 

When I tried to commented out the P-SUB VERSION, the one with nwell cleans but the one without nwell doesn't recognized.

 

How can we made that either or both are recognized? Please help.

 

 

Thanks and regards,

Rennel
