SC_MODULEでサンプル回路を作成する SystemC

SystemC

2023.12.29

SystemCの勉強がてらSC_MODULEを使ったサンプルコードを作成しました。

簡単な回路で、Producerがデータを送信してConsumerでデータを受け取って標準出力させます。

#include <systemc.h>

SC_MODULE(Producer) { // Producerモジュールを作成
    sc_out<int> dout;

    void generate_data() {
        for (int i = 0; i < 10; i++) {
            dout.write(i);
            wait(1, SC_NS);
        }
    }

    SC_CTOR(Producer) {
        SC_THREAD(generate_data);
    }
};

SC_MODULE(Consumer) { // Consumerモジュールを作成
    sc_in<int> din;
    void consume_data() {
        for (int i = 0; i < 10; i++) {
            cout << "Consumer received data: ";
            cout << din.read() << " at ";
            cout << sc_time_stamp() << endl;
            wait(1, SC_NS);
        }
    }

    SC_CTOR(Consumer) {
        SC_THREAD(consume_data);
    }
};

SC_MODULE(top) { // Topモジュールを作成
    Producer producer;
    Consumer consumer;

    sc_signal<int> data_channel;

    SC_CTOR(top) : producer("Producer"), consumer("Consumer") {
        producer.dout(data_channel);
        consumer.din(data_channel);
    }
};

int sc_main(int argc, char* argv[]) {
    top i_top("i_top");
    sc_start();
    return 0;
}

実行結果

Consumer received data: 0 at 0 s
Consumer received data: 0 at 1 ns
Consumer received data: 1 at 2 ns
Consumer received data: 2 at 3 ns
Consumer received data: 3 at 4 ns
Consumer received data: 4 at 5 ns
Consumer received data: 5 at 6 ns
Consumer received data: 6 at 7 ns
Consumer received data: 7 at 8 ns
Consumer received data: 8 at 9 ns
