Honored ContributorHello friends... i am also having a problem in programming FPGA....i want to read the pixel values of an image and i created a file with "hex" values of pixel using MAT lab and now i want to read that file and use those values in my verilog program...please help me in solving this issue...i am using altera's quartus ii software and DE2 kit.....
Regards, Gupta.
Honored ContributorYou can read some things about file IO in verilog here : http://larc.ee.nthu.edu.tw/~lmdenq/doc/fileio.htm
You can only use for synthesis or for memory initialisation in testbenches, and maybe to initialise RAM-blocks during synthesis. StefaanHonored ContributorHello...thanks for your reply...i had already seen the link that you had sent to me....but it was showing errors in quartus ii when i try to run the sample programs available in this link...is there any different syntax to run the program in quartus ii???
regards, Gupta.Honored ContributorUnfortunately, you didn't tell what you exactly want to achieve.
According to Quartus doc, only $readmemb and $readmemh are supported for memory initialisation. See specifying the initial contents of inferred memories in verilog hdl designs. Hex files can be most easily used as memory initialisation files with Ram MegaFunction.
