reading a file in verilog

[veeru]

Hello,
I am writing code for text compression in verilog.
I am struck at initial phase.
How can i read a long text file in verilog , other than using the
{readmemh} statement.
because it has the limitation of perticular memory size.but I want to
read a text file of 156kB.

I used the c=$fgetc( fp) statement but it is showing error that

Name 'fgetc' could not be resolved
Illegal right hand side of blocking assignment

Please give some suggestion

Thanks
Sagar

Try $fopen and $fscanf.

Verilog-2001 added general purpose file I/O. However, if $fgetc is
not being resolved, that implies that your simulator does not support
it. It is possible that a command line switch is required to turn on
the 2001 features. You should check your simulator documentation.

If your simulator does not support file I/O, you can try doing a web
search for Chris Spears' PLI implementation of file I/O system tasks.
