Design and validation methodology of FPGA-based motor drive for high-temperature environment

摘要

This paper presents a scalable design and verification methodology for FPGA-based motor drives for aircraft application, working at high-temperature environment. ProASIC^Plus from Actel Family (0.22 μm digital CMOS 4 Layer Metal Flash-Based CMOS Process) was chosen to implement the studied motor drive which consists on a current control. The design is implemented at a frequency of 24 MHz and junction temperature above 125°C. The die is supplied with 2.25v. The proposed methodology is based on similar ASIC design verification including synthesis, place and route, timing analysis steps for each control block. As entire system verification, a Real-Time Simulation (RTS) of the electrical systems is used to guarantee the proof of the motor drive functionality under several operating conditions. Co-simulation results are provided in order to prop up efficiency and interest of the proposed methodology in such application.
