Nexys4 DDR MIG控制器引脚文件

目前网上只有ucf文件，vivado不兼容ucf格式

使用c++字符串转换的xdc格式代码

使用C++写的转换代码（修改参数可以对任何代码使用）

#include <iostream>
#include <string>

using namespace std;

//set_property -dict { PACKAGE_PIN J15   IOSTANDARD LVCMOS33 } [get_ports { SW[0] }];

//NET "ddr2_addr[10]"                          LOC = "R2"      |   IOSTANDARD = SSTL18_II             ;         

string stringConver(string a) {
    string port;
    string pin;
    string type;

    int length = a.length();

    int i = ;
    for (; i < length; i++) {
        if (a[i] == '"') {
            port = a.substr(, i - );
            break;
        }
    }

    for (i++; i < length; i++) {
        if (a[i] == '"') {
            pin = a.substr(i+, );
            break;
        }
    }

    for (i++; i < length; i++) {
        if (a[i] == '=') {
            i++;
            for (int j =;; j++) {
                if (a[i + j] == ' ') {
                    type = a.substr(i+, j);
                    return (string)"set_property -dict { PACKAGE_PIN " + pin + "   IOSTANDARD " + type + " } [get_ports { " + port + " }];";
                }
            }
        }
    }
    return "";
}

int main() {

    string proto[];

    for (int i = ; i < ; i++) {
        getline(cin, proto[i]);
    }

    for (int i = ; i < ; i++) {
        cout << stringConver(proto[i]) << endl;
