使用 Vivado HLS 工具 通过 3 线-8 线译码器用模块化建模的方式实现 4 线-16 线译码器的功能，写出源文件和激励文件

好的，我明白了。以下是使用 Vivado HLS 工具通过 3 线-8 线译码器用模块化建模的方式实现 4 线-16 线译码器的源文件和激励文件。

源文件：

#include <ap_int.h>

void decoder_3_8(ap_uint<3> input, ap_uint<8>& output) {
#pragma HLS INTERFACE ap_ctrl_none port=return
#pragma HLS INTERFACE ap_none port=input
#pragma HLS INTERFACE ap_none port=output

    ap_uint<8> temp = 0;

    switch(input) {
        case 0:
            temp = 0x01;
            break;
        case 1:
            temp = 0x02;
            break;
        case 2:
            temp = 0x04;
            break;
        case 3:
            temp = 0x08;
            break;
        case 4:
            temp = 0x10;
            break;
        case 5:
            temp = 0x20;
            break;
        case 6:
            temp = 0x40;
            break;
        case 7:
            temp = 0x80;
            break;
    }

    output = temp;
}

void decoder_4_16(ap_uint<4> input, ap_uint<16>& output) {
#pragma HLS INTERFACE ap_ctrl_none port=return
#pragma HLS INTERFACE ap_none port=input
#pragma HLS INTERFACE ap_none port=output

    ap_uint<8> low = 0;
    ap_uint<8> high = 0;

    decoder_3_8(input.range(2, 0), low);
    decoder_3_8(input.range(3, 3), high);

    output = (high, low);
}

激励文件：

#include <ap_int.h>
#include <iostream>

void decoder_4_16(ap_uint<4> input, ap_uint<16>& output);

int main() {
    ap_uint<4> input;
    ap_uint<16> output;

    input = 0;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 1;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 2;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 3;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 4;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 5;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 6;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 7;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 8;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 9;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 10;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 11;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 12;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 13;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 14;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    input = 15;
    decoder_4_16(input, output);
    std::cout << "Input: " << input << ", Output: " << output << std::endl;

    return 0;
