Setting option duplicatemodel=ignore in spectre does not work

Frode Telsto

I run ADEXL (IC6.1.6) and want to redefine a model, and have tried to add duplicatemodel=ignore in my spectre simulations. I have tried to add: 

myOpt options duplicatemodel=ignore

in my modelfile that is included in the simulations. 

I have also tried to add duplicatemodel=ignore in Options->Analog->Miscellaneous->OTHER OPTIONS->Additional Arguments.

But I still get an error when I run my simulation: ERROR: .... Model `nch' has already been defined.

  • Hi Andrew,

    Thanks for your input. It helped me finding that the problem is binning. Your example works for me too, but when I add binning to the model it fails. See my modified example below.

    model nch bsim4 {
    1:type=n
    2:type=n
    }

    inline subckt nch_mac (d g s b)
    parameters w=1u l=1u

    nch_mac (d g s b) nch_mac w=w l=l
    model nch_mac bsim4 {
    1:type=n
    2:type=n
    }
    ends nch_mac

    myOpts options duplicatemodel=ignore
    // new definition to map it...
    model nch nch_mac

    M0 (D G 0 0) nch w=2u l=0.2u
    VD (D 0) vsource dc=1.2
    VG (G 0) vsource dc=0.8
