Write data in testbench

Whether it is possible in testbench to write the data to a file not in text, and in a hexdecimal code. And if it is possible, as?

I think it is not possible. but you can use any programming language to convert the txt file. I had previously change between BMP file and Text (output of VHDL test bench using MatLab".

I already have understood it too. It is a pity.

you only need to do effort in conversion programs and the steps will be forward for further work

I'm not sure if I understand the original question. If you're asking if you can read and write hex data from text files in your test bench, the answer is yes.

I believe the library is IEEE.std_logic_textio and the functions that you want are hread() and hwrite().
