We are looking for a highly skilled Research Associate with experience in RISC-V architecture. The successful candidate will be responsible for adding a Hardware AES and ASCON Accelerator to the RISC-V CVA6 core. This role requires deep knowledge of hardware design, cryptographic algorithms, and the RISC-V instruction set architecture (ISA). You will work closely with the AES and ASCON designers in our team to ensure seamless integration and optimal performance of the cryptographic accelerators.

Key Responsibilities:

Design and Implementation:

• Integrate a Hardware AES Accelerator and ASCON Lightweight Cryptography Accelerator into the RISC-V CVA6 (Ariane) core.

• Implement memory-mapped interfaces or custom instructions for the accelerators to interface with the CVA6 core.

• Collaborate on the integration of the accelerators into the core's execution pipeline.

RISC-V ISA Extension:

• Define and implement custom RISC-V instructions to utilize the AES and ASCON hardware accelerators, if needed.

• Modify the RISC-V CVA6 decode and execution stages to handle the new cryptographic instructions.

• Work out the toolchain to ensure assembler, compiler, and simulation support for the custom instructions.

Verification and Testing:

• Conduct simulations to evaluate the performance, latency, and throughput of the accelerators within the CVA6 pipeline.

• Work closely with the AES and ASCON accelerator design team to ensure proper testing and debugging of the hardware integration.

Job Requirements:

• Master’s degree in Electrical Engineering, Computer Engineering, or a related field.

• Proven experience with RISC-V architecture, especially with custom instruction extensions and pipeline modifications.

• Proficiency in HDL languages (Verilog, VHDL, or SystemVerilog) and RTL design.

• Proficiency in toolchain modification, including the ability to extend assemblers and compilers (GCC, LLVM) for custom hardware instructions.

• Proficiency of FPGA development tools such as Vivado, Quartus, or similar for prototyping.

Preferred Additional Skills:

• Strong understanding of ASIC/FPGA design flows, including synthesis, place and route, and timing closure.

• Experience in cryptography and implementing cryptographic algorithms in hardware (AES, ASCON, etc.).

We regret to inform that only shortlisted candidates will be notified.
