Weird Compile Error

[~~ VerilogMan ~~]

Hey,
I am gettin an error at this line :
'define counter 1b'0

Error is :

** Error: C:/Documents and
Settings/Zoroastreus/Desktop/Verilog/Serial_To_Parallel.v(13): near "'d":
syntax error
** Error: C:/Documents and
Settings/Zoroastreus/Desktop/Verilog/Serial_To_Parallel.v(13): Illegal digit
for specified base in numeric constant



... NO idea why ??? :(

Make sure your define starts with a `grave not a 'single quote' and move the
b for binary to the other side of the tick.

`define counter 1'b0

NICE :) it got fixed but i used to work that way no ?
Now I am getting more errors :|

I suspect there's a line above "input clk;" that isn't properly terminated
with a semicolon. A module declaration port list *does* end with a
semicolon before the external inpu/output/wire/reg definitions.

I don't seem to have so much of a problem with semicolons,
though I do still find it a little strange. I remember learning
years ago about the difference between PL/I and Pascal. In PL/I
semicolons are statement terminators, in Pascal they are separators.
The difference appears most around END and ELSE.

Now, why is it that verilog doesn't use them on END?

The thing is that it's very annoying,
at school my code was working , and now at home I get all these errors ... I
think it's because of the version of ModelSim is not the same :|

Correct, i had forgotten a ";" at the end of my module declaration ! :)
I get a lot of errors with this type of statement:

input parallel_data[1:0];
** Error: C:/Documents and
Settings/Zoroastreus/Desktop/Verilog/Top_Module_Decoder.v(7): near "[":
expecting: ';'


and another error :
encoded_w_errors_out = encoded_w_errors;

** Error: C:/Documents and
Settings/Zoroastreus/Desktop/Verilog/Top_Module_Decoder.v(33): near "=":
expecting: IDENT

You have so much stuff that should never have worked anywhere.
Inputs have the range before the identifier. 2-D inputs are not supported
in Verilog. So...

input [1:0] parallel_data;

is the "encoded_w_errors_out = encoded_w_errors;" supposed to be a
continuous assignment or is it in an always block, using the unusual
blocking operator?

This almost looks like something a prof would give to find out how little
someone actually knows about Verilog. Do you have a coworker that could
look over your shoulder as opposed to spending time here fixing your code?

No, to be honest, this is not my code man , we trying to build a convolution
encoder
Each of us has to do part of the code... I did mine ,....
And I am supposed to do the testbench too ...
But all the stuff my partner sent are half not working ! He has his own way
of coding... and it's a pain to look for the errors
I have been over his codes for the whole day ... and I have to do get my tb
done for trw :|

Make your partner fix his non-working code.

ANYTHING assigned in an always block either with a plocking operator or a
non-blocking operator cannot be a type wire. Typically the reg is used but
I believe integers would work as well.

This is super-simple Verilog. You should know this if you're "Verilog Man."
If your partner doesn't have it right, have him fix the code or get rid of
him - you're better off doing it right the first time than correcting his
mistakes.

I like to help people out but I'll bow out of further comments on your
errors. Good luck, man.

My lab partner is my friend ... can't get rid of them...
I found already *a lot* of errors, but after a while especially when it is
not your code, you don't see everything ...
thanks anyways

PS: I am verilog man , because I will be a verilog master
