So deep and clear... An average student can learn from your videos.. Jaise hi koi question aata hai dimag mein you already explained that in your video.. Really nice work.. 😇😇

[@ComponentByte]

Thank you for your kind appreciation.
I always believe in concept and not just the theory and try my best to educate myself first and then deliver the knowledge. I also appreciate negative comments so that I can rectify my mistake.

Wish you a happy learning and all the very best. Have a great future.

hello, i have a homework to do, i have a mips32 program, and i added a bcd module and display_driver module, to show my name on the 7 segments display, but the i ideea of the homework is to use .coe file to make that, can you help me?

Hi sir, Can we read values other than files in Verilog? I mean as we are using scanf() in C Language

[@ComponentByte]

You mean you want to read letters or some sentence like scanf()
If yes then it is only possible at simulation level and not at synthesis level because reading a sentence in verilog doesn't generate hardware and verilog is a hardware description language.
$display and $monitor() in verilog mimic scanf () behaviour

[@mdtutorial7240]

Thanks it's working fine for binary input as well as hexadecimal input.but what about decimal number input...??? I want to read my text file which is in decimal number but these commands are not working for me... please help.

[@ComponentByte]

To my knowledge it won't read decimal. It can only read hex and binary as no construct for decimal like b- binary, h- hex
Please change decimal to binary or hex using tools like matlab and then read it. Thanks.

Hello sir, first of all thanks a lot for discussing this memory read and write operation such a great way, but in the memory writing case I am writing the same code as you, but it writes 0 to 126 instead of 0 to 127, could please tell where I am making the mistake?

No, it's not synthesizable.

These codes are not working in Xiling Vivado.

[@ComponentByte]

It should work. Please check what is it showing on xilinx simulator

@@ComponentByte Thank you for instant reply .I tried both the code given in this video . If possible please check . Really struggling for my project"Calcuator " which says * I've to read the data from file using fopen and perform calculation using FSM and data can include maximum of 3 paranthesis.i.e() * If you can guide me it will be very helpful as at initial stage only(i.e reading the data) .I'm not getting the result so that I can move further do FSM logic to do calculation. *Do you have any mailid so that I can contact, I've to submit by tommorrow morning* . Please Help. Thank you again for Instant reply.
