Because we care, we empower and we excel. We believe in the power of diversity. Spread over 3 continents, 1900 colleagues from 50 nationalities shape the best imaginable future.

Project Description

Some of our circuits contain a CPU and a ROM that cannot be changed after the silicon manufacturing. In case a software issue is discovered on the manufactured chip, it would require a costly rework of the ROM.

A solution, already in place for years, to avoid modifying production masks for fixing small software bugs is the patch controller. It is a piece of hardware that can be configured after manufacturing to alter a few assembly instructions into correct ones.

Melexis is developing a new 32-bit platform (RISC-V CPU and AHB bus based) as the continuation of our homemade CPUs. So, new peripherals, such as the patch controller, have to be developed for the new bus protocol.

The target of this internship is then to design and verify a component handling patches compatible with the AHB bus protocol and our RISC-V CPU.

During this internship you will have the opportunity to gather knowledge on CPU architecture and software debugging, use GCC and Cadence tools for linting, code coverage,  simulation and formal verification.


Expected results

  • A SystemVerilog design database of the patch controller
  • A set of SystemVerilog self-testable test cases fully covering the design
  • A formal proof of the correct behavior of the patch controller.

Your profile

  • Master 1 or Master 2
  • Optionally, basic knowledge of CPU architectures
  • Basic knowledge of VHDL and/or Verilog

We offer

Joining Melexis for your internship is the opportunity to build up your know-how in a high-tech, international and dynamic company, benefit from the experience and training of our experts and enjoy the welcoming and friendly atmosphere of our Paris office team which is specialized in Digital Design and counts 20 employees.
