本文從故障激活的條件入手，利用五值邏輯，對瞬態電流測試中的延時變化進行波形分析和波形計算，採用並發模擬演算法，編程實現了一個iddt測試的故障模擬器。實際電路中由於製造工藝的限制，邏輯門的延時並不相同，而是在一定范圍內變化，引起波形變化的時間不確定。This system is developed based on high performance, low cost and many controllers inside of the embedded processor, and enlarged gpio for the plat of the hardware and software. this system is applied to the high - speed numerical control carving machine. show the operate interface by lcd, input the control code from the keyboard, the data is readed from the usb interface and store that in sdram
