A 6-month internship starting in 2025 - For students in their last University, Engineering schools (computer science, electronics, embedded systems).

Candidates must have the right to study and work in France.

Locations: Villeneuve-Loubet, France. Hybrid work allowed.

Objective

To develop formal verification IP based on a new methodology to test Codasip RISC-V IPs.

Background

Formal methods are used for CPU verification at Codasip. We have several extensions in consideration to improve the verification performances and extend its scope.

As our intern, you will be responsible for analyzing these proposals, selecting one or two, and implementing them as new tools or verification components. They will then be applied to real RISC-V CPUs.

Desirable outputs

• An implementation of the methodologies on a suitable Codasip RISC-V IP.
• An analysis of respective performance, in terms of:
• Ability to identify bugs (artificially injected and perhaps real).
• Achievable depth of bug-free confidence.
• Some reusable verification IPs, including drivers and formal test benches.

You are our ideal candidate if you have:

• Knowledge of Verilog or SystemVerilog (or similar HDL) and experience writing synthesizable RTL.
• An understanding of RISC-V or other CPU microarchitecture.
• A solid foundation in mathematical logic.
• Experience with shell, Tcl, Python, or other scripting languages.
• Familiarity working with Linux-based operating systems.
• Demonstrable experience undertaking self-led research or project work.
• Good communication skills and the ability to clearly summarise and share technical information and experimental results.

You may also have:

• Experience with linear temporal logic or SystemVerilog Assertions.
• Specific experience with formal verification tools and techniques such as bounded model checking, sequential equivalence checking, SAT/SMT solvers, etc.
