How to implement this equation in VerilogA

princemahmmod

 Hi,

Anyone can you please help me how to write module the following equation in verilogA???

y = x/ (a * exp(-0.5 *((x-b)/c)^2)) +d

    Hi princemahmmod

    Would you please start a new thread for your question? By the way, there is a verilogA manual here:

    $MMSIMHOME/doc/veriaref/veriaref.pdf


    Best regards

    I split this into a new thread. I agree with Quek, it doesn't make sense to mix different subjects in the same thread - it makes it much harder to follow.

    Here's an example:

    `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

    Note that the parameter values I just made up - I was primarily ensuring the syntax was correct.

    Regards,

    Andrew.

    I also posted this in response to your question on the Designer's Guide forums.

    I will split this off into a new thread when I get into the office. In general, it's best not to clutter existing threads with new topics.
