Reusable Verification Environment for a RISC-V Vector Accelerator Quiroga, Josue Genovese, Roberto Ignacio Díaz, Ivan Yano, Henrique Ali, Asif Sommez, Nehir Palomar Pérez, Óscar JImenez, Victor Rodriguez, Mario Dominguez, Marc Àrees temàtiques de la UPC::Informàtica::Arquitectura de computadors Open source software Verification Risc-V Vector Accelerator UVM Coverage Random Binary Generation This paper presents a reusable verification environment developed for the verification of an academic RISC-V based vector accelerator that operates with long vectors. In order to be used across diverse projects, this infrastructure intends to be independent of the interface used for connecting the accelerator to the scalar processor core. We built a verification infrastructure consisting of a Universal Verification Environment (UVM) which is capable of validating the design performing co-simulation of the vector instructions. Moreover, we provided a set of tests and an automated test generation, simulation and error reporting infrastructure. This paper shares our experience on verifying a complex accelerator used in two distinct projects, with different interfaces.
