本文提出了一种用硬件描述语言(HDL语言)对系统控制专用集成电路(ASIC)进行自顶向下设计和仿真的通用方法。使用两种语言：VHDL语言(超高速集成电路硬件描述语言)用于ASIC的建模和实现，spectreHDL语言用于控制环境的模拟建模。不同的模型允许最终的ASIC从控制算法的优化到ASIC体系结构的逐步优化。每个阶段都通过混合(模拟/数字)模拟的功能验证来完成。将该方法应用于感应电机的直接转矩控制。在阐述DTC原理的基础上，对算法的验证和优化进行了研究：数值计算方法的选择、二进制格式和类型的选择。然后，为实现该算法进行了体系结构优化。针对扭矩调节精度高、处理时间短的特点，采用32位定点特定格式类型，优化了硬件结构。
This paper presents a general "top-down" methodology for design and simulation of system control ASIC (application specific integrated circuit) using hardware description languages (HDL). Two languages are used: VHDL (very high speed integrated circuit hardware description language) for ASIC modeling and realization, and SpectreHDL for analog modeling of the control environment. The different models allow the optimization step by step of the final ASIC from the optimization of the control algorithm to the ASIC architecture. Each stage is completed by a functional validation resulting of mixed (analog/digital) simulation. This methodology is applied to direct torque control (DTC) of an induction machine. After describing the DTC principle, algorithm validation and optimization are studied: choices of numerical calculation methods, binary format and type. Then, architecture optimization is developed in order to implement the algorithm. Due to torque regulation accuracy and reduced treatment time, optimized architecture using 32 bits fixed point specific format type has been hardware implemented.
