In the MIG example design simulation, everything is ok and simulation passes. The attached PDF is the block design of the ZCU102 board, and you can see in the upper right hand corner the DDR4 MIG implementation on the far side of an AXI Smart Connect block. We need to customize the MIG design to meet some unusual requirements. Rank is limited to 2 or 4 for LRDIMMs and 1 or 2 for all other devices. I'm using MIG's example simulation sources that vivado provides by default (the one shows up when I click "Open example design", and I found out iDDR4 is used in the testbench file), but I slightly changed my DUT to generate several different example testcases. I hope to target AUP or KUP. My logic consists of 3 parts. 8V . DDR4 is highly suited for processor-based systems and in any application that require mass storage. tRP and tRCD are the functions of memory speed of I'm testing the MIG for DDR4 with the AXI interface. sv file: (please refer to attached as an example) Update the instantiation of the mig_v5_0_ddr4_mem_intfc to match the updated port-list. 1, DDR3 v6. 40 . 2) system clock source. 1\board. I then create the DDR4 IP interface (controller and phy) and add it to my design as a sub-module. Download the micron_075_OK. Bring out the PHY-ports to the top-level. If I am forced to set component width to 8, and memory width to 16, then the MIG generated will provide 2 dqs_c, dqs_t, dbi_n per 16 bit "chip". Xilinx documentation is organized around a set of user design processes to help you find relevant content for your design needs. 12). I use zynq ultrascale+ MPSoC to connect 9 DDR4 components, which composes 72 bits DDR4 memory. For example: c0_ddr4_*, c1_ddr4_*, c2_ddr4_*. Currently I'm practicing using xilinx MIG for DDR4, through user application interface.
