Functional verification project for the CORE-V family of RISC-V cores.

core-v-verif

Functional verification project for the CORE-V family of RISC-V cores. This project is under active development.

NEWS UPDATES:

2020-06-12: a new "Board Support Package" for CV32E40P simulations is installed at cv32/bsp. This BSP should be used to compile/assemble your test-programs. The Makefiles for both the CORE testbench and UVM verification environment have been updated to use this BSP.
2020-06-02: The Imperas OVPsim Instruction Set Generator has been integrated into the UVM environment as the Referenece Model for the CV32E40(P). You will need to obtain a license from Imperas to use it.
2020-02-28: The OpenHW Group CV32E40P is now live!
This repository no longer contains a local copy of the RTL. The RTL is cloned from the appropriate core-v-cores repository as needed. The specific branch and hash of the RTL is controlled by a set of variables in cv32/sim/Common.mk.

Getting Started

First, have a look at the OpenHW Group's website to learn a bit more about who we are and what we are doing.

The design and verification documentation for the various CORE-V cores is located in the OpenHW Group's CORE-V documentation repo. Reading the Verification Strategy is strongly recommended.

If you want to run a simulation there are two options:

1. To run the CORE testbench (based on the RI5CY testbench), go to cv32/sim/core and read the README.
2. To run the CV32E40P UVM environment, go to cv32/sim/uvmt_cv32 and read the README.
