Verification of a RISC-V based SOC

RISC-V is an open instruction set architecture (ISA) developed at the University of California, Berkeley.. The RISC-V ISA has been designed with small, fast, and low-power real-world implementations in mind, Hence it will be useful for modern devices such as cloud computers, high-end mobile phones and the smallest embedded systems. Such uses demand that the designers consider both performance and power efficiency. The instruction set also has a substantial body of supporting software, including the entire tool chain to successfully compile and run complex code on the ISA.

There are several companies adopting (or planning to adopt) RISC-V architecture for their next SOC design. In this project we have implemented a complete verification framework for a RISC-V based SOC. This framework is designed in UVM and incorporates the following UVM based VIPs.

  • i2c
  • QSPI
  • UART
  • GPIO

We have developed several tests to exercise the entire SOC. Each test contains two parts

  • a "C"-based component which provides the instructions for the CPU to execute
  • an UVM-based component which provides external stimuli through the VIPs and provides overall control of the test
