I received the screenshot. Your waveforms are ok, but when I run the simulation in your zip I get different waveforms. I don't see the din_ready reassert, it always remains low. I can't understand how it's possible, the test bench file is the same. Mabybe depends on the simulator used. I'm using QuestaSim-64 10.6g.

Hi, Thank for your update. For your information, I am using Modelsim - Intel FPGA Edition 10.5b at which this design is created and tested with, based on previous information that I got from wiki. You might want to try with Modelsim to see if it works as a workaround. Thank you very much. Best regards, Chee Pin

    If I use Modelsim it correctly works. Anyway I need use QuestaSim in order to create an UVM testbench. I'll try with an other QuestaSim version.
