verilog read binary file

if it can, how to do that

verilog read binary

I have tried , it seemed it cannot!

 

[patrickli]

verilog binary file open

use PLI , can read binary file.

verilog reading hex data

use PLI , can read binary file.

What PLI i should use ? please

verilog $memreadb

hi,
Verilog can open the binary files.
How to use the data in binary files?

If you want to get the data for memory, you can use the $memreadb().
If you only want to open the binary file, you may use the $open().

binary read verilog

We have to use $readmemb() to read files in binary form. $readmemh() to read hex files. I used it many-a-time, let you check out once. I hope no need of PLI or whatever mentioned....,...,

reddy

Hi reddy:
I can use this PLI for using hex data or bin data from ordinary file,
but whenever reading obj code file, modelsim shows

************************************************
warning (vsim-PLI-3409) Illegal binary digit 'ç' in data at line 1 of "./ac97.obj"
# ** Warning: (vsim-PLI-3409) Illegal binary digit ' : E:/project/Test1/read_obj/top.v(8)


what's wrong?

Please

what's wrong?

pls check your obj file, there is illeagal letter in your obj file (not 0 or 1)

good luck!

verilog binary read

(1)binary file(.obj) & readmemb are two different concepts.

binary file(.obj) refers to the storing format of the file in machine.

the source of readmemb refers to files which content just include ASSIC character 0 & 1. The storing format of the file itself is not binary. The contents of the file what people can see are like binary strings.

(2)verilog1364-2001 can read binary file, using $fopen. But the simulator need the ability to support v2k function.

(3) another way is to use pli

verilog+binary files

use fid=$fopen("???","r");
$fread(temp,fid,"%h");
temp defined as register

$fread read .v verilog

if you use option like "w", each time you open the file will clear the original content of the file automatically. So use "a+" instead.

verilog 1634-2001 standard illustrates it clearly.

I uses $readmemb(),but I can not read into the memory when I pre-simulation at Modelsim 5.6,why?
I have put the test bench and *.vec at the same path! Sometimes I can read into the memory,are the software-Modelsim had some problem?

Even I didn't use parameter "w"
, it still clear the content of the obj file,my environment
