Hi Sir,

I'm Adzim. Thanks for using Intel Community.

According to the KDB here, it's looks like the global and soft resets can only trigger the mem_reset_n signal.

Are you using the example design in your simulation?

If not, can you simulate your IP with the example design?

Which Quartus software that you used?

Regards,

Adzim
