cxl6712 Ask a question 2022-11-07 17:04: Question Why does the register delay input signal fail?

I recently do a small task tutor, in the use of FPGA development encountered a problem, would like to ask you to help look at it. I have a register signal reg data_en_buff in my circuit, and I want this register to delay the input signal data_en by one clock cycle. When I had the data_en jump back and forth between 0 and 1, as shown in the figure below, the data_en_buff was able to succes sfully delay the data_en one clock cycle.(I use modelsim for simulation) But when I make the data_en jump to high after a certain point and keep it high, as shown below, the data_en_buff...; Focus on question 0  0  0Comment
