The MIG 7 Series DDR2/DDR3/DDR3L controller, upon reset, completes a JEDEC standard compliant initialization sequence. The simulation testbench skips the initial 200 s delay to speed up simulation times. In hardware, this requirement is observed. After initialization, the PHY logic completes the calibration process while adhering to all timing parameters and sending all required commands as defined by the JEDEC standards. Upon successfull calibration, the memory controller then ensures full JEDEC compliance.
