64-bit RISC-V Application Processor Core
The A70 is a 64-bit RISC-V application processor aimed at systems running Linux.
Overview
The A70 is a powerful 64-bit RISC-V application processor aimed at systems running Linux. The core has an in-order 7-stage pipeline enabling greater than 1 GHz frequencies in 22nm HPC.
The core includes integrated L1 data and instruction caches, an interrupt controller and RISC-V Debug module optionally with PC trace.
Like all Codasip RISC-V cores it is possible to create custom instructions using Codasip Studio to extend the ISA and to generate corresponding hardware and software development kits.

A formal-based approach for efficient RISC-V processor verification
In this article, we go through a formal-based, easy-to-deploy RISC-V processor verification application. We show how, together with a RISC-V ISA golden model and RISC-V compliance automatically generated checks, we can efficiently target bugs that would be out of reach for simulation.
Efficient Verification of RISC-V processors
Processor verification, however, is never trivial but requires combining the strengths of multiple verification techniques. This technical paper considers how to efficiently verify a RISC-V processor using a multi-layered approach known as the Swiss cheese model adapted from the world of avionics.
