Responsibilities
Work with the architecture team to understand and define power management requirements.
Architect, design and implement core clocking, reset and power management solutions.
Microarchitecture development and specification, with clear documentation and collaborative design culture.
Perform initial sandbox verification and collaborate with the verification team to create and execute thorough verification plans.
Collaborate with the physical implementation team to meet frequency, area, and power goals.
Work with software teams to enable and optimize power management features.
Requirements
3+ years of experience in CPU and SoC clocking, reset, and power-management logic designs.
Experience in high-performance, energy-efficient CPU and SoC designs.
Expertise in CPU and SoC clocking, reset design, and power management, including:
Reset control and design strategies: clock distribution, dynamic clocking, clock gating, and boundary crossing
Power state definition and PMU design
Dynamic and static power reduction techniques, including retention and power-up/down sequencing
DVFS and Di/dt mitigation strategies
Understanding of DFT, MBIST, Debug and error handling in CPU designs
Power-aware simulation
Proficiency with hardware (RTL) design in Verilog, SystemVerilog, or VDHL.
Good understanding of RTL quality checks (Lint, CDC, RDC, etc.). Hands-on Spyglass is a plus.
Attention to detail and a focus on high-quality design.
Team-oriented mindset with collaborative engineering approach.
Knowledge of at least one object-oriented and/or functional programming language.
Background of successful CPU or SoC development from architecture through tapeout.
BS/MS degree in EE, CE, CS or related technical discipline, or equivalent experience.
Nice to have
Experience with AMBA Interconnect Protocols (AXI, AHB, APB).
Experience with AMBA Low Power Protocol Interface, including P-channel and Q-channel.
Experience with Scala/Chisel, Bluespec, or other hardware/software DSLs.
Knowledge of RISC-V architecture.
Experience with Git/Github, Jira, Confluence.
