How to load Intel Hex File ?

[Slawek Grabowski]

Hello,
Does anyone know how to write a ROM initialized form Intel Hex file ?
Is it possible in Verilog ?

Any help will be appreciated,

As far as I know the answer is NO, BUT I achieved this in my last
project via a
conversion routine (I am sorry that I don't have that routine with me any
more...), basically
Verilog expects the ROM data to be in so called "Verilog Format" which loks
like

@<address> <data>
@<address> <data>
@<address> <data>
....

And Verilog code reads it with system tasks "$readmemh" and/or "$readmemb".

Where <address> and <data> could be either in binary or hex (Corect me if I
am
wrong here) depending on whether you use "$readmemb" or "$readmemh"

Now once you get hold of the format of "Intel Hex" I believe it is straight
forward to convert
the same.

Good Luck.

Srini,
thank you for your answer,
So, I am going to write a simple C program to
convert Intel Hex into Verilog Format.
I will use $readmemh to initialize the memory.

Short question:
Is Backslash ( \ ) allowed in a verilog netlist?

In verilog a backslash introduces a variable name that might include
special characters (like '[' or '/' for example') this allows
you to pull in names from outside verilog that have different syntaxes
that might clash with normal verilog naming conventions - such names are always terminated
with a space for example:

\abcd[1] - a net called 'abcd[1]'
abcd[1] - bit 1 of 'abcd'
\abcd [1] - bit 1 of 'abcd'
\abcd[1] [1] - bit 1 of 'abcd[1]'
