Error in verilogA

sreeni

Hi to all

Am designing one model in verilog-A. 

In that i have defined one function (Charge_low) and while using it in the main design it showing some error.

Am not able to understand the error.

 hsp-vacomp: Error: syntax error

 hsp-vacomp:     ['SBCNTFET.va',399]

 hsp-vacomp:     Qs_low1 = Charge_low(  2.32  ,H1,b1_1,b0_1)-Charge_low(`alpha_1,L1,b1_1,b0_1);
 hsp-vacomp:                                                         ^

 Error was showing @ the "," after H1.

All variables in the function are declared as real and defined.

Please let me know what may be the error.

 

Thanks

  •  Hi Andrew,

    I got habituated to post in cadence forum.

    My code is of some 600 lines i can't post it.

    Am adding few more lines of that function declaration and where am getting error.

     

    analog function real eeta;
            input x,y;
            real x,y;
            begin
                eeta  = hspsqrt(x*y*y+y);
            end
        endfunction 

        /*************************************************************************/
       
       
        analog function charge_low;
        input x,y,b1,bo;
        real x,y,b1,bo;
          begin
             charge_low = eeta(x,y)*((b1*(y-(1/2*x)))+(2*b0))+((b1)/(4*hsppow(x,1.5)))* hspln(((0.5+(x*y))/(hspsqrt(x)))+(eeta(x,y)));
           end
        endfunction

     I posted 'eeta' function also, as a refence.

     And here is those lines where it showing error.

     

    Qs_low1 = Charge_low(`alpha_1,H1,b1_1,b0_1)-Charge_low(`alpha_1,L1,b1_1,b0_1);

    Please clarify this.

     Thanks
