If I have a block of memory initialized by an instance of lpm_ram_dq.
// instantiating lpm_ram_dq lpm_ram_dq ram (.data(datain), .address(addr), .we(we), .inclock(inclk), .outclock(outclk), .q(dataout)); If I want to read out data at "addr (e.g. addr = 2)" to an output variable outdata using nonblocking assignment, how should do it? Is there a similar format like "outdata <= mem[2]" or "assign outdata = mem[2]"?Link Copied

I believe you instantiate the lpm_ram_dq in a custom module, for e.g. as in the following code fragment: module LPM_RAM_DQ_1024_16_DM (din, dout, addr, clk, wr, outdata); parameter width = 16; parameter depth = 10; input clk, wr; input [depth-1:0] addr; input [width-1:0] din; output [width-1:0] dout, outdata; wire high; assign high = 1; lpm_ram_dq myRAM (.data(din), .q(dout), .address(addr), .we(wr), .inclock(clk), .outclock(high)); defparam myRAM.lpm_width = width; defparam myRAM.lpm_widthad = depth; // 2^10 = 1024 addresses defparam myRAM.lpm_indata = "REGISTERED"; defparam myRAM.lpm_outdata = "UNREGISTERED"; defparam myRAM.lpm_file = "RAM_1024_16bits.mif"; assign outdata = dout; endmodule i.e. use the assign statement to point your outdata output to the lpm_ram_dq .q output
