Read external stimuli file in ModelSim...

[massive]

Hi to all!

I want to apply many stimuli signals to my simulation. Is it posssible to place them in text file and read it in Model Sim with TCL or other way?

this is just a language related question, if you use VHDL, you just use std.text.io lib and then using readline and read statement to read from stimuli file

Save wave to file.do, Then you cad load it when you want to run simulation!

use ieee.std_logic_textio.all;
use std.textio.all;

file master_file : TEXT is in "E:\??\??\??";

begin
process
variable Lbuf : Line;
readline(master_file, Lbuf);
...

some supplement to roger's

after readline statement, you can use read as follow
let take adder as an example, you have operand A and B
and output result
just add the following to roger's code

varialbe opA, opB, result
read(LBuf, opA)
read(LBuf, opB)
read(LBuf, result)

A_i <= opA;
B_i <= opB;

wait for ........
assert result_o = reuslt
...............
