altera_onchip_flash

The submodule "altera_onchip_flash_avmm_data_controller" in this IP has some problem. WRITE_STATE, this FSM will unexpectedly been hold when I continues write data to flash. It will cause status...

I do some simulation. Two type coding looks totally different on technology map.

A type coding : "write_count != 0"

The FSM will fail if there is a glitch on clock.

B type coding : "write_count > 0"

The FSM will be fine if there is a glitch on clock.

By the way, my device is MAX10. I think MAX10's clock may have some problem.

Where can i share these simulation file?

Can anyone teach me why these two type coding make so much different on the end?

Thanks a lot.
