Does ADE license is necessary for export hspice netlist in virtuoso?

lightyear

friends:

I have the hspice license, and I want to export netlist with hspice in virtuso.

But the exported netlist miss parameters,  like below:

.subckt nvlv IN OUT VDD VSS
xm0 VDD OUT IN VDD pmoslvt m=pPar("nfp")
xm1 VSS OUT IN VSS nmoslvt m=pPar("nfn")
.ends nvlv

correct content should like this:

.subckt nvlv IN OUT VDD VSS  ln=10  wn=20
xm0 VDD OUT IN VDD pmoslvt m=pPar("nfp")  l=ln w=n
xm1 VSS OUT IN VSS nmoslvt m=pPar("nfn")
.ends nvlv


---------------

export steps:

0. open a schematic

1. click "Launch" -- "Plugins" -- "Simulation" --  "Other"

  Simulation option will appear in the top menu

2. click "Simulation" -- "Initialize" , open the initialize environment window and set the run dirctory

3. click "Simulation" -- "Netlist/Simulate..." , it will popup "netlist and simulate" windows,

      click "Simulator Name"  and select hspice ,at last, click  " ok or "apply"  , netlist will be generated but miss parameters.

I watched some netlist related videos, they all use ADE, but we don't have this license at the moment, so I can try it ,

ADE is neccessary?

Thanks very much.

    There are two interfaces to HSPICE that Cadence provides in Virtuoso:

    1. The plugin from the schematic editor. This requires "hspice" views with NLP formatting properties on the stopping view. This is an older "digital" flow which (in general) is not supported by any mainstream PDKs. This is the one you've tried using, but if the views are not set up properly, then the parameters will be missing - especially if you start seeing pPar() in the netlist, you're using a "CDF-based" or "ADE-based" netlisting flow and this won't work.
    2. The hspiceD interface within ADE. This is the CDF-based approach where a PDK has hspiceD stopping views and info in the CDF to determine how to netlist components; this is almost certainly what you have, and in which case it need an ADE license plus the "Virtuoso® Analog HSPICE Interface Option" license.

    I would suggest you contact your account team.
