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，只要写出源文件和激励文件

好的，我会尽力回答您的问题。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 线译码器的功能的源文件和激励文件。

源文件：

#include "ap_int.h"

void decode3to8(ap_uint<3> in, ap_uint<8> &out) {
#pragma HLS INTERFACE ap_ctrl_none port=return
#pragma HLS INTERFACE ap_none port=in
#pragma HLS INTERFACE ap_none port=out

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

void decoder4to16(ap_uint<4> in, ap_uint<16> &out) {
#pragma HLS INTERFACE ap_ctrl_none port=return
#pragma HLS INTERFACE ap_none port=in
#pragma HLS INTERFACE ap_none port=out

    ap_uint<8> dec1;
    ap_uint<8> dec2;
    ap_uint<8> dec3;
    ap_uint<8> dec4;

    decode3to8(in.range(2, 0), dec1);
    decode3to8(in.range(3, 1), dec2);
    decode3to8(in.range(2, 0), dec3);
    decode3to8(in.range(3, 1), dec4);

    out.range(7, 0) = dec1;
    out.range(15, 8) = dec2;
    out.range(23, 16) = dec3;
    out.range(31, 24) = dec4;
}

    in = 0;
    decoder4to16(in, out);
    printf("in = %d, out = 0x%x\n", (unsigned int)in, (unsigned int)out);

    in = 1;
    decoder4to16(in, out);
