    You make the AC_meas_tb as the testbench. Can you check inside the AC_meas_tb.v files, what is your module name there? currently, the tools are complaining the testbench issue.

I searched the Internet for an example of working with Flash memory, thinking that there was a mistake somewhere in my project and therefore FFFFF was always read from Flash. On FpgaCloud, I found a project like this:

https://fpgacloud.intel.com/devstore/platform/17.1.0/Standard/max10-user-flash-memory-data-incrementing-burst-read/.

I started the simulation and saw that FFFFF is always read from Flash. This project was created by Altera (Intel), I am sure that there is no error in it.

Why is FFFFF always read from Flash?

PS I am using Quartus 17.0.
