初学OPNET，个人觉得要注重三个方面：

1，OPNET 的网络仿真机制，包括三层建模、离散事件驱动仿真机制、通信机制、

有限状态机等，主要是看帮助文档中的原理部分；

2，OPNET 的核心函数，多看帮助文档中各核心函数的介绍以及示例很有帮助；

3，掌握ODB 的调试，个人感觉OPNET 的调试不难，关键是要善于从OPNET 的仿真

原理入手来找可能的错误所在，我的经验就是按着数据走的流程来分析。

另外，有时间的话，可以找一个OPNET 提供的标准模块代码来看看，有利于理

清通信的流程和掌握写代码的一些常用技巧。-novice, personally feel that we should pay attention to three aspects : 1, OPNET's network simulation mechanism including the three tiers of modeling, discrete event simulation-driven mechanisms, communication mechanism, finite state machine, the key is how to help document the principle; 2, OPNET's core function, see more of the help documentation on the core function and helpful examples; 3, master of debugging ODBC, OPNET the personal feeling is not hard to debug, The key is to be good at OPNET start of the simulation theory may come to the mistake, My experience is taking the data continues to flow analysis. In addition, the time, then we can find a OPNET is the standard to look at the code, help sort out the communication process to write code and master the techniques.
