How to save DC currents to 'spectre.dc'?

Hello,

I ran the command " spectre input.scs" in a terminal. In the resulting output file "spectre.dc", it only contains all the DC node voltages  as following. How could I (1) save the DC current of an instance terminal (2) only save specific voltages that I claimed?

 Here is the output file "spectre.dc".  I don't know what does 'int_d', 'int_s' mean.

Following is setup in the 'input.scs'. I tried few modifications but it didn't work.

Thank you very much.
