Created January 29, 2014 14:12
Read output ports in Verilog and VHDL. This was written for my blog post.
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
entity ReadOutputCorrect is
PORT (
in1 : IN STD_LOGIC;
in2 : IN STD_LOGIC;
in3 : IN STD_LOGIC;
o1 : OUT STD_LOGIC;
o2 : OUT STD_LOGIC

Not all variables declared as reg gets synthesized to registers in verilog.
module ThisRegWontProduceReg(
output reg o1,
input i1, i2, i3
);
always @(i1, i2, i3) begin
if (i1 == 1'b1) begin
o1 <= i2;
end else begin
o1 <= i3;

Where not to assign wire and reg in Verilog. This was written for demonstration purposes in my blog post.
module RegAssignmentWrong(
output reg o,

input in2
);
assign o = in1 & in2;
endmodule
