日常生活中，隨處可見標榜微電腦控制的產品，廣泛使用於家電、工廠自動化、汽車電子、感測、燈光、醫療電子、玩具、電源甚至人機介面等諸多市場...等等。
以8位元單晶片微控制器為例，因應市場要求體積輕薄短小和成本壓力下，必須整合所有功能至單一晶片內，使得整個系統周邊零組件數量變的屈指可數。由於微控制器主宰著整個系統運作！只要微控制器發生當機就視同宣告系統當機。
在系統整合設計時，即提供多種重置路徑，將可能發生的當機或不穩定性，使用硬體電路、微控制器重置機制與軟體技巧來排除或隱藏，讓微控制器在最短時間內自我恢復至正常狀態，防止微控制器進入死迴圈，避免造成系統停擺，依此來提高產品在使用上的可靠度與穩定性。由此可知重置機制對於系統預防當機是多麼地重要！
本論文旨在研製一『任意波形產生器』作為測試平台，測試平台使用微控制器控制DAC電路即可輸出各種電源開關機特性測試曲線，測試待測微控制器在各種電源變動下的動作狀況，以自動化測試取代傳統使用手動操作電源供應器開關機測試方式。
此『任意波形產生器』測試平台主要用於微控制器晶片開發驗證階段，可自動測試微控制器在各種不同電源變動條件下是否會發生當機並記錄至測試平台EEPROM中。設計人員事後可由當機時的測試時間及曲線形式，研判微控制器是何種重置機制失效？針對機制失效原因進行改善，提高穩定度，在晶片量產後可大幅降低客戶應用時的種種電源開啟重置問題。

In daily life, everywhere claiming to be products of micro-computer control, widely used in home appliances, automotive electronics, factory automation, automotive electronics, sensing, lighting, medical electronics, toys, power and even human-machine interfaces, and many other markets ... , And so on.
8-bit single-chip microcontroller, for example, the volume of short, light and cost pressures in response to market requirements, we must integrate all functions into a single chip, making the whole system peripheral spare part number change only a handful. Microcontroller to dominate the operation of the entire system! Microcontroller crashes regarded as a declaration of system crashes.
System integration design, offers a variety of reset path that the machine may occur crashed or instability, the problem eliminate or hide by the hardware circuit, the reset mechanism of micro-controller and software techniques, so that the microcontroller in the shortest timeself-recovery to the normal state, to prevent the micro-controller into an infinite loop, to avoid system downtime, and improve the reliability and stability of the product in use. Can be seen that the reset mechanism of how important for the system to prevent crashes!
This thesis is to develop an "arbitrary waveform generator” as a test platform, the test platform to use microcontroller to control the DAC circuit can output various testing curve for power-on and power-off. To test the action of the micro-controller in a variety of power changes, automate test instead of a traditional manually operated power supply test methods.
This test platform of arbitrary waveform generator used for development of micro-controller chip validation phase, automated testing of microcontrollers whether crash in the various conditions of power supply variation and record the test result into EEPROM. The designers judged that the micro-controller what reset mechanism is not working? To improve the mechanism and stability will significantly reduce customer applications in all the power-on reset problem.
