Hi

I was designing an RC network and I decided to have 3 modules in my source file-2 for definitions of the resistor and capacitor and the main module where instances of the R and C were created(with the appropriate interconnection). This is the code I wrote:

module rescap(posr,negc);
electrical posr,negr,negc;
resistor res(.p(posr),.n(negr));
capacitor cap(.pos(negr),.neg(negc));
endmodule

module resistor(p,n);
parameter real rn=1k from [1:inf];
electrical p,n;
analog
begin
V(p,n) <+ rn*I(p,n);
end
endmodule

module capacitor(pos,neg);
parameter real c=100 from [1:inf];
electrical pos,neg;
analog
begin
I(pos,neg) <+ c*ddt(V(pos,neg));
end
endmodule

My test bench file looks like this:
module rctest(posr,negc);
electrical posr,negc;
wire negr;
resistor #(.rn(1000)) res(p,n);
capacitor #(.c(100)) cap(pos,neg);
vsource #(.type("sine"),.dc(0),.ampl(5),.freq(5000)) vin(posr,negc);
endmodule

Now when I compile this, I get an error message that "Named Port Association is not valid for analog primitives in Affirma-AMS". I am confused. I thought named port association was valid in V-AMS.

Am I missing something?

Thanks MightyMouse !! I'l try that !
