help with a strange problem in cadence

[ddrr]

Hi, all

Under the cadence schematic design environment, I get a device symbol from the PDK, then attach it to it's model file. In that case, the simulation result is strange and wrong.

If I get the symbol from the analoglib, the simulation result will be all right.

I don't know what happened here. Is it something wrong with the configuration?

Expecting for your reply! Thanks a lot!

can you show what error message it shows?

A poly resistor.

In the first casе parameters from CDF not transferred to netlist. Maybe incorrectly installed PDK or spectre view changed.
