automatic insertion of E2R and R2E connect modules

freitas

Hello,

I'm trying to run a very trivial example to see how the automatic insertion of E2R and R2E connect modules works. Please find the code below. Unfortunately, I get the following elaboration error:Elaborating the design hierarchy: Top level design units: top

Discipline resolution Pass...

ncelab: *E,CUVDRF: Could not determine discipline for top.xr.

Would I be missing some elaboration option?

thanks,

 

`include "constants.vams"

`include "disciplines.vams"

module top;

wreal r, xr, wr;

assign xr = 3.14;

ams_electrical_src e_s1(r);

// causes insertion of Electrical2Real

// connection module

  ams_electrical_dst e_d1(xr);

// causes insertion of

// Real2Electrical connection module

  ams_wreal_src w_s1(wr);

// Coercion of SystemVerilog real variable

// to wreal

endmodule

 

module ams_electrical_dst(e);

   input e;

   electrical e;

  initial #10 $display("%M: %f", V(e));

endmodule

 

module ams_electrical_src(e);

  output e; electrical e;

   analog V(e) <+ 5.0;

endmodule

 

module ams_wreal_src(w);

     output w; wreal w;

     assign w = 2.5;

endmodule

  • I could run your example by creating forum.f (the code was in forum.vams):

     forum.vams
    -reflib $AMSHOME/tools/affirma_ams/etc/connect_lib/connectLib
    -discipline logic
    -amsconnrules CR_full_fast
    -timescale 1ns/1ps
    -ieinfo ieinfo.txt
    run.scs

    where run.scs contained:

    tran tran stop=1u

    and then I did:

    irun -f forum.f

    or if I wanted to see things in simvision:

    irun -f forum.f -access +rw -gui

    Note it's the -discipline logic which was the key. You didn't say how you were running the simulation, so I guessed...

    Regards,

    Andrew.
