Background

CORE-V is a family open-source of microprocessor cores based on the RISC-V Instruction Set Architecture.  The first two members of the family, CV32E and CV64A are derived from open-source implementations created by the PULP-Platform team at ETH Zurich.

Scope

OpenHW Group CORE-V Cores produces industrial quality fully documented and verified implementations of the CV32E and CV64A

Description

The tangible products produced by OpenHW Group CORE-V Cores includes:

  • Complete documentation: micro-architecture and a user manual.
  • Implementation: RTL model and synthesis scripts for both ASIC and FPGA implementations.
  • Verification: both dynamic (simulation) and static (formal) verification environments.

Legal Issues

All products produced by the OpenHW Group shall be covered by one or more of:

  • Solderpad Hardware License, SHL v2.0
  • Apache License v2.0
  • Eclipse Public License, v2.0

SHL is a permissive license implemented as a 'wrapper' around Apache v2.0.  See https://solderpad.org/licenses/SHL-2.0 for more information.

Note that some artifacts may be covered by SHL v0.51 or soley Apache v2.0 only (not SHL).

Why Here?

The open-source RISC-V Instruction Set Architecture created by UC Berkley and now maintained by the RISC-V Foundation inspired a growing community of open source hardware development.  Some believe that RISC-V will do for hardware what Linux has done for software.  The OpenHW Group is committed to this open source future and the Eclipse Foundation is a natural home for OpenHW projects.

Project Scheduling

The OpenHW Group is working to "tape-out" (release a build for silicon fabrication) in the second half of 2020.  A more detailed schedule can be found at https://github.com/openhwgroup/core-v-docs/tree/master/cores.
