Hi guys,
How can I change the spectre-netlist format from "mx0 (net0 net1 net2 net3) pmos w=5u l=0.5u m=1" to "mx0 (net0 net1 net2 net3) pmos wr=5u lr=0.5u nf=1" automatically(without addtional perl script) when I use analog artist to extract it and simulate?

I try to editing the cell ("symbol" and "spectre" view) with CDF tool, but there is no w/l/m papramters in the extrated netlist after modification. Thanks.

Hi Ken,
Thanks for you advice.
The purpose that I don't use perl or find/change in the text editor to change w/L/m to wr/Lr/nf is that I do not want to modify the netlist and I want to use the "netlist and run" button on ADE directly. So I prefer to having a wr/Lr/nf-based netlist extracted automatically by "netlist and run" with all possible setting, for example, how can I change the nmos parameter so that the netlist extracter tool (though I don't know which tool the cadence use) will get wr/Lr/nf instead of w/l/m.

Best regards,

Hi Ken,
Thanks for your patience. However it seems the multiplicity factor in "inline" block should evaluated to be a number instead of "nf". Please refer to my detailed information:

Foundry's mosfet model is in sub-circuit format as:
subckt n33_ckt_rf (1 2 3 4)
parameters lr=0.35u wr=10u nf=2
......
main (11 21 31 41) n33_rf l=lr w=wr m=nf
model n33_rf bsim3v3{
...
}
ends n33_ckt_rf

My netlist is the following as your advice:
subckt lcvco net0 OUTN OUTP VDD VSS
   M1 (net034 net037 net082 VSS) nmos w=4u l=400.00n m=2
   .....
ends lcvco

inline subckt nmos (d g s b)
   parameters wr lr nf
   nmos (d g s b) n33_ckt_rf w=wr l=lr m=nf
ends nmos

The simulation errors are:
Warning from spectre in `t_lcvco', during circuit read-in.
   M1: `w' is not a valid parameter for an instance of `nmos'.  Ignored.
   M1: `l' is not a valid parameter for an instance of `nmos'.  Ignored.
Error found by spectre in `nmos':`M1', in `lcvco':`I0', during hierarchy
       flattening.
   nmos: The value for the multiplicity factor `m' should evaluate to a
       number.

The error tells me that I should assign a number to nf in the inline block, however the multiplicity factor is different in different mosfet such as M1,M2 etc. What is your comment? Thank you very much!
