Hardware Design Of AC Servo Motor Simulator Based On SoPC

The research of this subject utilize the characteristic of FPGA( Field , programmable Gate Array): high integrated level, small volume, low consumption, high dependability and online debug, the method of SW/HW Co-Design, the characteristic of VHDL language: hiberarchy design methods, convenient revise, nice portability; and design a platform of AC Servo Simulator (ACSS) based on SoPC. After load the simulator software, it can simulate the motion of 16 motors at the same time, on the Simulator platform. And it can give the CNC a closed loop test.The first chapter introduces the present status and development of SoPC technology. Detail the method of SoPC design.In the second chapters, describes the system design of the ACSS.The beginning is the Excalibur EXPA10 arthitecture, and the following is the ACSS architecture design. The following chapters are the main body of the paper:In the third chapter,detail the design of AHB-ISA bridge.At the starting, introduce the AHB Bus and ISA Bus specification.Then,there is the description of the bridge design on design procedure and architecture partition.The forth chapter is the circuitry and logic design of Servo Simulator Board. In the partition of circuitry, first is the introduction of devices' character; then, show the connection of the devices.In the logic partition, describe on the module architecture.And in the up tow chapters design, do the emulate and function test.At last, introduce the Servo Simulator Board's driver design.This subject is the sub-subject of knowledge innovation project of Chinese Academy of Sciences in the period of the State's Tenth Five-Year Plan that is open and intelligent systematic platform of numerical control.
