simple_bram_ctrl.v에 true_dpbram.v를 instantiation 을 어떻게 해야 할까요?
제공해 주신 simple_bram_ctrl.v 마지막에 true_dpbram.v 를 instantiation 한 코드만 아래와 같이추가한 단순한 코드입니다. 전체 코드도 첨부 하였습니다. true_dpbram #( .DWIDTH (DWIDTH), .AWIDTH (AWIDTH), .MEM_SIZE (MEM_SIZE)) u_TDPBRAM( .clk (clk), .addr0 (addr0), .ce0 (ce0), .we0 (we0), .q0 (q0), .d0 (d0), // no use port B. .addr1 (0), .ce1 (0), .we1 (0), .q1 (), .d1 (0) ); ////////////////////////////////////////////////////////////////////////////////// // Company: Personal // Engineer: Matbi / Austin // // Create Date: 2021.01.31 // Design Name: // Module Name: simple_bram_ctrl // Project Name: // Target Devices: // Tool Versions: // Description: To study ctrl sram.
