As a Lead Cache Subsystem Microarchitect and RTL design engineer at SiFive you will be part of a team of engineers who are passionate about designing industry-leading CPU cores and cache subsystems, based on the revolutionary open-source RISC-V architecture. We are looking for people who are as excited as we are about working in a fast-paced dynamic environment to bring new hardware IP to market quickly, with high quality and exceptional performance.
Responsibilities:
- You will architect, design and implement new high performance cache subsystems in SiFive's RISC-V CPU core generators and enhance features and performance in existing ones.
- Working on the microarchitecture development and specification; ensuring that knowledge is shared via great documentation and participation in a collaborative design culture.
- Performing initial sandbox verification and work closely with the verification team to create and execute detailed verification test plans.
- Working with the physical implementation team to implement and optimize physical design to meet frequency, area, power goals.
- Collaborating with the performance modelling team for performance exploration and optimization to meet performance goals.
Requirements:
- Relevant industry experience working on high-performance, energy-efficient cache subsystem designs, ideally within a CPU or GPU subsystem.
- A background of a successful cache subsystem development from architecture through tapeout.
- Expertise in multi-level coherent cache architectures and designs.
- Experience with TileLink or other similar interconnect architecture.
- Proficiency with hardware (RTL) design in Verilog, System Verilog or VHDL.
- Attention to detail and a focus on high-quality design.
- Ability to work well with others and a belief that engineering is a team sport.
- A Bachelor's or Master's degree in EE, CE, CS or a related technical discipline, or equivalent experience.
