Hi guys, I have a problem with creation of a lookup table in verilog. I want to export data from matlab to a verilog file. It is a lut with one input and one output. Can you suggest me a command for avoiding write about 200 line of code. Thanks.

you could write a Matlab script printing the relevant code snippet
(inside of a case block) in verilog syntax. Something like this
(untested!) Matlab code here:
for i=1:length
fprintf('8'h%x: out <= 8'h%x\n', i, value(i));
end
The result you copy & paste into you verilog file.
Ok, this is a good way to solve problem of copy,Thanks. But about the LUT creation itself? For example if i want a LUT of a function sqrt((1/x)+1) with input fixed because i have a fixed point representation, how can i get the function output? Is there a function ? excuse me, but i've never done this.

Of course there is a function in Matlab to calculate this. And there is the function fixdt() in Matlab to create a fixed point representation of your numbers. This is more a Matlab problem rather than a Verilog problem, right?
well, I ned info about connection of the 2 softwares... you gave me. Finally I was able to create this lut. Now I can continue to study Verilog. Thank you, Mr Meerbann.
