This paper describes a powerful. easy-to-use. potable data acquisition system (LOGGER) for ABS and TCS developments. The system is specially designed to support in-vehicle test of ABS and to acquire different kinds of data such as internal logic variables, vehicle driving characteristics, break pressures, and driver's manipulating conditions.<br/> The system receives internal variables from ABS and TCS ECU by using CAN, which results in reducing the number of needed wires and lengthening a required distance to communicate with ECU, keeping the communication speed high. The acquired data are transmitted to PC in real time and they are analyzed in details by using a PC-based software (ABSVIEW).<br/> The system can be mainly applied to developments and evaluations of control algorithm and failsafe software for ABS and TCS<br/>

In the manufacturing of VLSI circuits, variations of device characteristics due to the slight differences in process parameters drastically aggravate the performances of fabricated devices. Therefore, it is very important to establish optimal process conditions in order to minimize device sensitivities. In this paper, we used one-dimensional process simulator, SUPREM-Ⅱ, and two-dimensional device simulator, MINIMOS 4.0 in order to extract optimal process parameter which can minimize changes of the device characteristics caused by process parameter variation in the case of short channel nMOSFET and pMOSFET device. From this simulation, we have derived the dependence relationship between process parameters and device characteristics. Here, we have presented a method to extract process parameters from design trend curve(DTC)obtained by process and device simulations.
