compare modelsim simulation result with a theory text file using vhdl

Question

I would like to compare a modelsim stimuli with a math theory function

for that I must export my simulation data from modelsim to .lst file and then create vhdl program who read the .lst file and compare it with math.do file which contain a integer input value

I'm trying to make a list but I don't got what I want the file list

if this is the list, what mean the second column?

I don't know how to export data from modelsim ? the second question is: is this method that I'll do is right or I must do something else?

please help me. thanks in advance

Answer 1

First QA:

A "Delta delay" is an infinitesimal delay (= ~0 s delay). It is used to evaluate sequential events within a time-step. E.g. combinatorial statements:

a <= not b;
b <= '1';

Is equivalent to

process
begin
    a <= not b;
    wait until b'event;
end process;
process
begin
    b <= '1';
    wait;
end process;

Thus after b <= '1' at delta cycle 1 the first process will be triggered again and a <= not '1'; will be evaluated at delta cycle 2.
