ビジュアルプログラミングで高位合成 その6

Posted at

概要

ビジュアルプログラミングで組み合わせ回路を組み立てて、シュミレーションして、verilogを生成します。
高位合成です。
実は、今の実装では、半加算器、全加算器が高位合成できません。
半加算器の高位合成を実装しました。検証します。
検証編

テストベンチを書く。


module x(input A, input B, output Sum, output Carry);
	assign Sum = (A ^ B);
	assign Carry = (A & B);
endmodule

module test;
	reg A;
	reg B;
	x u(.A(A), .B(B), .Sum(Sum), .Carry(Carry));
	initial
	begin
		$display(" A   B   Sum Carry");
		$monitor(" %b  %b  %b  %b", A, B, Sum, Carry);
		A = 0;
		B = 0;
	#10;
		A = 0;
		B = 1;
	#10;
		A = 1;
		B = 0;
	#10;
		A = 1;
		B = 1;
	#10;
		$finish;
	end
endmodule

iverilogでシュミレーション実行

>iverilog ha0.v

>vvp a.out
 A   B   Sum Carry
 0  0  0  0
 0  1  1  0
 1  0  1  0
 1  1  0  1
ha0.v:27: $finish called at 40 (1s)
