[SOLVED] Veriloga $fopen command

[kavitha_rapolu]

Hi,

Where does the file get stored in when we use $fopen("%C:r.dat") in Veriloga ?

I can't find the file after running the simulation.

you should use like this

The $fopen Function
Use the $fopen function to open a specified file. The $fopen function reuses channels associated with any files that are closed.
Example:
integer myChanDesc ;
myChanDesc = $fopen ( "myfile" ) ;

See this example 2.

Example:
The following code fragment illustrates how to open and write
simultaneously to two open files:
integer mcd1 ;
integer mcd2 ;
integer mcd ;
@(initial_step) begin
mcd1 = $fopen("file1.dat") ;
mcd2 = $fopen("file2.dat") ;
end
.
.
.
mcd = mcd1 | mcd2 ; // Bitwise OR combines two channels
$fstrobe(mcd, "This is written to both files") ;
The file, file1.dat, can also be named %C:r.dat, to track the name of the netlist file from which it is run.

Thank you. So after running the code , in which directory do you find the file
file1.dat?

In my case, I ran my code and after that I dont find my file1.dat in the results directory.
