    Hi @KhaiChein_Y_Intel

    Thank you for the additional information. However, I'm afraid my question still has not been answered:

    According to my VGAController.sv file, there should be a chain of components like this:

    "a) dataH <-- iDataCopy <-- dataIncoming <-- iData

    But what I see inside the RTL Viewer is this:
    b) dataH <-- iData

    Where did iDataCopy and dataIncoming go??

    Has the compiler has optimized my design in such a way that it no longer works?? How can I ensure that my chain is synthesized as I expected it to be in (a) above?"
