Responsibilities

• Build and maintain a modular flow for building Synopsys ZeBu models using the SiFive internal build system. This includes transitioning compilation steps into the SiFive wake-based build environment to support seamless integration with other internal flows.

• Execute root cause and failure analysis across RISC-V CPU hardware and software components.

• Facilitate debug using ZeBu features like waveform dumping and utilize ILA and JTAG debuggers to troubleshoot and validate designs.

• Develop failure hypotheses through systematic, step-by-step elimination of potential causes.

• Create and support Python-based scripts to enhance and automate debug workflows, and support the integration of ZeBu runtime automation into the SiFive manager ecosystem.

• Work cross-functionally and maintain active partnership with both the software and validation engineering departments.

Requirements:

• 1+ years of experience with a Bachelor’s or Master’s degree in Computer Science or Electronics and Communication Engineering is required.

• A strong understanding of logic design is essential.

• Prior exposure to logic design using Verilog and the subsequent porting of designs onto FPGA platforms is necessary.

• Practical experience with Linux-based operating systems and scripting languages such as Python and BASH is mandatory.

• Candidates must possess a positive attitude, a proactive approach to continuous learning, and a commitment to achieving excellence in their work.
