However, implementing an EOS system on a chip is complex and needs full verifications. This paper introduces our design of Hardware/Software co-verification platform for EOS design. The hardware platform contains a microprocessor board and an FPGA (Field Programmable Gate Array)-based verification board, and the corresponding software includes test benches running in FPGAs, controlling programs for the microprocessor and a console program with GUI (Graphical User Interface) interface for configuration, management and supervision. The design is cost-effective and has been successfully employed to verify several IP (Intellectual Property) blocks of our EOS chip. Moreover, it is flexible and can be applied as a general-purpose verification platform.展开更多

Due to programmable feature of FPGAs, faults of FPGAs can be easily tolerated if fault sites can be located. A hardware/software （HW/SW） co-verification technique for FPGA test is proposed in this paper. Taking advantage of flexibility and observability of software in conjunction with high-speed simulation of hardware, this technique is capable of testing each input/output block （IOB） and configurable logic block （CLB） of FPGA automatically, exhaustively and repeatedly. Fault cells of FPGA can be positioned automatically by the proposed approach. As a result, test efficiency and reliability can be enhanced without manual work.展开更多
