I am trying to follow the tutorial: http://www.fpgadeveloper.com/2014/08/creating-a-custom-ip-block-in-vivado.html#comment-61211. I do steps 2-5. The line where I found reg_data_out <= slv_reg1; is within this block of code in my_multiplier_v1_0_S00_AXI.v:
always @(*)
begin
if ( S_AXI_ARESETN == 1'b0 )
reg_data_out <= 0;
end
else
begin
// Address decoding for reading registers
case ( axi_araddr[ADDR_LSB+OPT_MEM_ADDR_BITS:ADDR_LSB] )
2'h0 : reg_data_out <= slv_reg0;
2'h1 : reg_data_out <= multiplier_out; // changed from reg_data_out <= slv_reg1, N Harrison 6/24.
2'h2 : reg_data_out <= slv_reg2;
2'h3 : reg_data_out <= slv_reg3;
default : reg_data_out <= 0;
endcase
end
end

I change it in step 5. However, I cannot follow step 6. I do not see where “slv_reg1” needs to be replaced with with “multiplier_out” and when I save, I do not notice that the “multiplier.vhd” file has been integrated into the hierarchy (step 8).

Can you please post a copy of your my_multiplier_v1_0_S00_AXI.v file so i can compare to my own?
