I'm having trouble with the DRC for OCL pins. I get the following error messages for the same net which has an OCL pin at one end, an INPUT pin at the other, and a resistor(R52) to my +2_5VD power:
1) "More than one driver on a net"
2) "Open Collector pin is not tied to VDD"
I tried adding R52 to the "pull-up symbols" and +2_5VD to "pull-up nets". Didn't work. Also Tried adding RES (DEVICE value) to pull-up symbols. I'm not sure how to define pullup symbols and pullup nets correctly.
What am I doing wrong?
