Hi guys, happy new year!! I'm currently trying to write and read data from my DDR3 SDRAM block. Instead of using any IP core, I want to write and read data diractly using Verilog in Vivado. But unforunitely, I can't find the XDC configition in XDC file of my board. so I'm stucking at how t `timescale 1ns / 1ps //ram.v module ram( input clk_i, input rst_i, input wr_en_i, input rd_en_i, input [7:0] addr_i, inout [31:0] data_io ); reg [31:0] bram[255:0];
