I tried to open a file ff.txt and write into it some random numbers say seven times. I used EDA playground website for it. Below is the link for that code as well as that code.
When I try to run I get error as
** Warning: (vsim-3533) [FOFIW] - Failed to open file "ff.txt" for writing.
Permission denied. (errno = EACCES) : design.sv(6)
My question is why don't I have access to the file ff.txt?
module fopenclose(); integer mcd,number; initial begin mcd=$fopen("ff.txt"); repeat(7) begin number=$random; $fdisplay(mcd,"Number is",number); end $fclose(mcd); end initial #2 $display("%d",mcd); endmodule
