Custom Netlisting in ADE

GaneshShamnur

Hi,

Below is my question regarding custom netlisting in ADE.

I have a simulatable design in ADE which is: Testbench( DUT + Stimulus) + Analysis( say tran) + Model-files being attached+ Save signals mentioned.

My requirement is to dump a netlist file with only circuit aspect of it ( only Testbech+Model-files) but not stimulus ( i.e Analysis and Save statements discarded) in it. Is there a way to do it ?

Even if it would require some amount of SKILL or OCEAN automation, I am fine to accept the solution. However, if ADE has a direct means to do so, I would very glad to recieve the solution.

Thanks,

Ganesh

  • Hi Ganesh,

    By a simulatable design, I assume you mean that you have an input.scs (assuming Spectre as your simulator).  The input.scs file resides in the <cell>/<simulator>/<view>/netlist directory of your projectDir (envGetVal("asimenv.startup" "projectDir").  If you look at the netlist file in that same directory, you should find just the connectivity only data, but this lacks the model definitions.  Does this help you?

  • And if you really want the model files that will be included, they're in a file called ".modelFiles" in the netlist directory (for spectre, at least).

  • Yes SharksFan, Andrew,

    When I meant 'simulatable design', I meant it as a design that could be simulatable from ADE, dumping 'input.scs' in the netlist directory etc.

    To elaborate more on my question, I would want to have a file similar to 'input.scs' where 'control/stimulus' statements are absent. A kind of ( netlistHeader + netlist) without netlistFooter contents. ( My end intensions are to have a file which has PURE circuit information, no trans, no save etc).

     Thanks,
    Ganesh

     

     

  • You could always create the netlist without defining any of the analyses, and disabling all the save statements from the Options->Save All. Or produce the netlist you want by concatenating the pieces in the netlist directory.

    But there's nothing that will produce the precise combination you want.

    Andrew.
