Same reg variable in an always block, Computer Engineering

Assignment Help:

What value is inferred when multiple procedural assignments made to the same reg variable in an always block?

When  there  are  multiple  nonblocking  assignments  made  to  the  same  reg  variable  in  a  sequential always block, then the last assignment is picked up for logic synthesis. For example

always @ (posedge clk) begin

out <= in1^in2;

out <= in1 &in2;

out <= in1|in2;

In the instance just shown, it's the OR logic that is the last assignment. Hence, logic synthesized was indeed the OR gate. Had the last assignment been the  "&" operator, it would have synthesized an AND gate.
