如何提取CDL时让电阻例化？一般为了layout的方便，电路中会标出电阻的W/L，所以提取的电阻CDL会这样：RGPS_ ...

Step 1: check (and try) if you get to generate correct netlsit from hspiceD views. -> You already mentioned your library did not have hspiceD views.

Alternative: use a (sed/awk/perl) script to post-process the CDL netlist.

    RGPS_1 net1 net2 $[RGPNC] $W=1u $L=10u

In your specific case, since you only need to post-process the resistor netlist format, it can be done by a fairly simple "sed" script.

Contents of the sed script (for instance, let me call it raw.sed) is as follows:

   s/\$\[//
   s/\]//
   s/\$//g

Excecute the following command under Linux:

   sed -f raw.sed YourNetlistFileName > raw.out

, where YourNetlistFileName is the name of original netlist file.
Check and see if the processed netlist in raw.out has the format you need.

Good luck!

This is not manual editing.
This automation is executed by (Unix/Linux) shell script.
