Title: Equation in verilogA
Post by princemahmmod on Apr 19^th, 2010, 10:21am

Hi,
Can anyone help me how to write in verilogA following equation???
y= x/ (a*exp(-0.5*((x-b)/c)^2)) +d

Your help would be greatly appreciated
Thanks

I didn't check whether this equation made any sense, and I didn't set the parameter values to anything meaningful - I just wrote it to illustrate the syntax:

Code:

`include "disciplines.vams"

module equation(y,x);
output y;
input x;
electrical x,y;

parameter real a=1.0;
parameter real b=1.0;
parameter real c=1.0;
parameter real d=1.0;

analog begin
V(y) <+ V(x)/(a*exp(-0.5*pow((V(x)-b)/c,2)))+d;
end

endmodule

Regards,

Andrew.
