Lead verification for a cache-coherent interconnect subsystem based on ARM CHI. Develop verification environments, protocol checkers, scoreboards, assertions, coverage models, and constrained-random tests covering coherency, ordering, flow control, retries, and integration. Analyze failures across specifications, RTL, and testbenches; drive verification strategy, coverage closure, methodology improvements, and durable fixes. Collaborate with architecture, design, formal, and software teams while mentoring engineers and supporting signoff.

Develop and maintain SiFive’s verification platform infrastructure, libraries, tools, and methodologies for design verification. Build functionality using Chisel and CIRCT, create Scala-based verification libraries and generators, and develop Python tools for querying design intent and metadata. Collaborate with platform technology teams, support end-to-end verification flows, and educate teams on best practices. The role requires compiled and scripting language experience, modern software engineering knowledge, and experience deploying production software.

Develops and deploys power analysis flows, models, and measurement infrastructure for SiFive processor IP. The role correlates power models with RTL and silicon, supports architecture exploration, and optimizes ASIC power across architecture, logic, and circuit levels. It requires advanced computer architecture knowledge, particularly high-performance out-of-order CPUs, along with software engineering practices for maintaining large object-oriented codebases.

Analyze and benchmark SiFive IP power consumption, correlate power models with RTL and silicon, work with architects and designers to optimize power/performance trade-offs, and innovate improvements to power analysis flows.

The role involves analyzing and optimizing power consumption in SiFive IP, guiding architecture for power efficiency, and improving power analysis flows.

Develop and deploy methodologies for measuring and analyzing power consumption of SiFive IPs. Guide teams in designing energy-efficient IPs through power modeling and analysis.

Design and implement CPU power management, reset, and clocking solutions. Collaborate with teams to verify and optimize designs based on RISC-V architecture.

Lead verification for a scalable cache-coherent interconnect subsystem: define strategy and test plans, build verification environments, checkers, assertions and coverage, verify CHI/ACE/CXL/AXI flows, create constrained-random and directed tests, debug across RTL/formal/software, and drive methodology and mentorship to improve verification quality and closure.

Lead verification for a scalable cache-coherent interconnect subsystem. Define strategy, develop environments, checkers, assertions and coverage, verify CHI/ACE/CXL/AXI flows, debug root causes, partner with architecture/RTL/formal teams, and mentor engineers to improve verification quality and signoff.

Design and implement highly-configurable TileLink interconnects, cache controllers, protocol bridges and other uncore RTL generators using Chisel/Scala. Drive performance and coherence improvements, integrate into Chisel/FIRRTL framework, collaborate on verification plans and documentation, and work with teams to deliver high-quality, configurable IP for SoCs.
