How to make a symbol in ADE reference a spectre netlist (Read 4071 times)

mlujan1965 New Member Offline Posts: 4	How to make a symbol in ADE reference a spectre netlist Jun 05^th, 2009, 7:57am Hello I have a loss model described with a spectre netlist. I would like to make a symbol to use in ADE that references the netlist rather than a schematic. How is this done? Thanks.

Then include that netlist in ADE -> Simulation Files ... -> Stimulus File. I have done successfully with a SPICE OPAMP netlist. Yawei

Thanks Yawei
I wrote a simple netlist for an RC see below:

simulator lang = spectre
subckt TestRC In Out GND
parameters Rval
R1 (In Out) resistor r=Rval
C1 (Out GND) capacitor c=10p
ends TestRC

I have edited the Base CDF and added Rval as Component Parameter

I keep getting the fllowing spectre error:

I1.R1: parameter 'r' : The parameter 'Rval' is used but not set.

What am I doing wrong?

Also is there a way to get the subckt netlist displayed in the
main netlist?

thanks

You need to add "Rval" as an instParameter in the spectre simulation information section of the CDF, so that it knows it needs to be netlisted for spectre. It sounds as if you have a parameter "r" that is being netlisted (which shouldn't be the case, since your subckt doesn't have "r" as a parameter). So check what parameters are being netlisted in the spectre simulation information part of the CDF.

Regards,

Andrew.
