我正在尝试将 Origen-Sim 连接到旧版模拟流程中，并且在让套接字连接正常工作时遇到了一些麻烦。

出于调试目的，我在simulator.rb 中添加了一个新条目，允许我手动启动模拟器：

    when :legacy
    #cmd = "sim na_origen2 -makeopts SOCKET='#{socket_id}
    cmd = "echo 'hi!'"
    puts(socket_id)

然后我用 +socket+{socket_id} 运行我的模拟器

我所看到的：

当我不传入套接字时，模拟器会因以下原因而死：

ERROR: No socket ID given to the simulator
ERROR: Couldn't connect to Origen app!
ncelab: *F,INTERR: INTERNAL EXCEPTION

和 Origen 只是挂起 - 正如预期的那样。

当我确实通过套接字时，我得到了同样的错误，但是Origen 然后在套接字上看到了一些东西但是崩溃了。EOM 错误。

完全披露 - 因为我正在运行一个遗留流程，所以我使用的是 ncsim 而不是 irun。为此，我使用 -loadpli libpli.so:origen_startup 运行。我想也许代码中的引导程序导致它运行两次，但将其注释掉没有效果：

/// Bootstrap vector, make the simulator execute init() on startup
// void (*vlog_startup_routines[])(void) = { init, 0 };

调试指导表示赞赏！也许一些简单的代码来测试连接？

没有什么比输入一个大问题来让大脑工作更重要的了。看来问题是 libpli.so:origen_startup 中的引导函数调用在细化和模拟期间都被调用。

通过向 origen.c 添加引导函数解决了这个问题：

PLI_INT32 bootstrap(p_cb_data data) {
      vpi_printf("Bootstrap Called!\n");
      init();
      return 0;
}

然后将 -libpli 更改为 libpli.so:bootstrap

这似乎解决了这个问题，虽然我还没有完全工作。一旦我得到其他一切工作，我将提交一份 PR。
