有网友希望了解用用什么方法来测试单片机系统的可靠性，邓宏杰指出：“当一个单片机系统设计完成，对于不同的单片机系统产品会有不同的测试项目和方法，但是有一些是必须测试的：
1．测试单片机软件功能的完善性。这是针对所有单片机系统功能的测试，测试软件是否写的正确完整。
2．上电、掉电测试。在使用中用户必然会遇到上电和掉电的情况，可以进行多次开关电源，测试单片机系统的可靠性。
3．老化测试。测试长时间工作情况下，单片机系统的可靠性。必要的话可以放置在高温，高压以及强电磁干扰的环境下测试。
4、ESD和EFT等测试。可以使用各种干扰模拟器来测试单片机系统的可靠性。例如使用静电模拟器测试单片机系统的抗静电ESD能力；使用突波杂讯模拟器进行快速脉冲抗干扰EFT测试等等。
“还可以模拟人为使用中，可能发生的破坏情况。例如用人体或者衣服织物故意摩擦单片机系统的接触端口，由此测试抗静电的能力。用大功率电钻靠近单片机系统工作，由此测试抗电磁干扰能力等。”
