Hi Chonlam,Sorry to bother you. Can you help me?I saw a jpeg_decoder project on Github, and since I just started learning JPEG , I didn't know how to use it. I asked the owner but didn't get a response, and of course I tried to write Testbench myself, but it didn't work. I saw that you pull a bug request in that project, I guess maybe you can use this IP core, so I come to ask for your help. Have you ever written the Testbench of this IP core? Would you mind sharing it with me? Thank you very much for your sharing, I am looking forward to your reply

Hi @Heshang6, I don't think it's proper to redistribute it without the author's permission. Did you reach the authors via [email protected]?

Thanks for your reply, this author wrote in code comments if you want test vectors please contact them, they are very interested in this IP is used in what place. I sent the mail sincerely, but in the past week didn't get the author's reply, I think the author is currently busy with other things, did not notice my email, But recently I am eager to learn how to use the decoder to help me with my project. Therefore, I really need your help now. Of course, first of all, I will not use this IP core to seek profits or publish it, I just want to help me complete my creation. Secondly, I will send an email to the author to show that I really need the test vector of this core and apologize to them. I have no other idea but to seek your help. Would you mind sharing it with me?

You can try Verilator to verify behavioral function: https://github.com/yakeshi/jpeg_decoder/tree/main/simulation. Hope it is of help to you.
