Software Engineer — RISC-V Random Test Generator

Company:

Job Area:

General Summary:

About the Role

You will contribute to a Python-based random test generation (RTG)framework and its companion assembler library that together form thecore of a RISC-V CPU design-verification toolchain. The RTG drives aJIT-style, simulator- coupled generator that produces ELF binariesexercising the RVA23.1 ISA - including privileged modes, virtualmemory, interrupts, vector, and cryptography extensions. Theassembler library provides the bit-accurate instruction encoding

layer that the RTG and other tools consume.

What You'll Do

• Implement new generation objects for RISC-V extensions; commonmicro-architectural scenarios; and complex data/control-flowcomposable idioms.

• Add instruction forms and encodings to the python companionassembler and verifying bit-level correctness against the RISC-VISA spec.

• Write and tune generation themes which are knob-driven testprofiles that compose objects to improve RTL coverage.

• Work within the privileged-software stack: exception/interrupthandlers, page-table builders, PMP configuration, and IMSIC programming sequences.

• Work with ISS and RTL verification engineers to triage failures,add targeted regression scenarios, and adjust constraint logic(register allocators, address-space managers, data fillers).

What We're Looking For

• 2-5 years of experience in CPU design verification, ISSdevelopment, or hardware-software co-design.

• Solid Python 3 skills; comfort with generator-based coroutines and object- oriented design patterns.

• Working knowledge of the RISC-V ISA: instruction encoding formats(R/I/S/B/ U/J, compressed, vector), CSR semantics, privilegelevels (M/S/U), and the memory model.Alternatively, similarknowledge for x86 or ARM.

• Familiarity with virtual memory (Sv39/Sv48), PMP, andtrap/interrupt handling.

• Exposure to random test generation flows or ISS/RTL co-simulationis a plus.

Nice to Have

• Compiler developmentexperience.

• Understanding of hypervisor and/or AIA/IMSIC interruptarchitecture.

• Familiarity with constraint-propagation libraries.

Minimum Qualifications:

OR

Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field and 3+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience.

OR

PhD in Electrical Engineering, Computer Engineering, Computer Science, or related field and 2+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience.
