A universal hardware emulator for verification IPs on FPGA: a novel and low-cost approach

Efficient and cost-effective functional verification strategies are more and more essential in digital integrated system design. This paper presents a low-cost approach to meet this challenge, introducing a universal hardware emulator designed for verifying various Intellectual Property (IP) cores on FPGA. We demonstrate the practicality and performance of this emulator through a use-case of verifying an advanced Integer Arithmetic Logic Unit (ALU) for the RISC-V ISA vector extension. The process of integration and the results obtained from the verification are presented and discussed. Preliminary findings indicate that the emulator can perform more than 1.1 million tests per second. This research contributes to the advancement of hardware verification techniques, providing researchers, universities, and small businesses with an accessible and effective solution.
