In our design a lot of nets are driven through series termination resistors. These are reported by DRC as "undriven". How can I convince DRC that these are indeed "driven"?
Just check resistor's pin type, it should be BI type.
Wouldn't that get me into trouble if I were to connect a resistor to e.g. ground? Thank you for your quick answer, by the way.
Such type of DRC check only valid to those schematics consisting of digital primitives.For today's schematics where lot of commecial system ICs be adopted and thier pin types be changed on different status, It's very difficult to develop an DRC engine which be able to catch up all connection issues without false warnings and errors.
Today's schematics have hundred of pages and then thounsans net, so every designer really need an intelligent enginer to catch up errors. I tried to write a script to do such of checks, but I found it's impossible without a model file .
Resistors should not have BI pintypes. This is often an unfortunate result of a translation. The pin types should really be Analog. The resistor does not drive a signal on either pin as a BI type would.
I agree, and "analog" is the pin type that was used.
