Why do I see that mem_reset_n and mem_cke assertion does not meet the JEDEC specification at Intel® Arria®10 FPGA DDR4, DDR3 IP EMIF IP simulation?

Environment

    Intel® Quartus® Prime Pro Edition
    External Memory Interfaces Intel® Arria® 10 FPGA IP
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You might see the DDR4 and DDR3 initializing sequence timing violation where JEDEC specification defines 500us at simulation.

Resolution

This is to shorten the simulation time and the actual hardware follows the JEDEC specification.
