I designed one rf analog amplifier in cadence using UMC 180nm components for rf. In schematic driven layout I can't establish contacts between pin and metal it shows me that contact doesn't exist in UMC_18_CMOS. I simply can't understand this, whether it is a problem of my FDK kit or having issue with incorrect installation, please help.Thank you.
Probably you should get in touch with whoever provided you with the PDK. It's hard to know what is wrong without seeing it. Customer Support could probably help if we can look at the data with you.
