Principal Physical Design Engineer, STA
BroadcomJob Title
Principal Physical Design Engineer, STA
Role Summary
Lead full-chip Static Timing Analysis (STA) for Broadcom's ASIC Products Division, ensuring timing closure for advanced-node, large-scale ASICs and multi-die integrations. Drive AI-assisted STA automation, collaborate with RTL, physical design, and DFT teams, and deliver sign-off-quality timing results.
Experience Level
Senior - 12+ years of hands-on ASIC STA and timing closure experience.
Responsibilities
Primary responsibilities include ensuring timing sign-off and improving STA flows and infrastructure.
- Own final timing closure across PVT corners and author/maintain SDC for functional and test modes.
- Deploy AI/ML automation within STA flows to reduce runtime and optimize shared compute infrastructure.
- Triage timing violations using automated workflows and data-mining to isolate root causes and remove marginalities.
- Drive timing ECOs and collaborate with RTL, Physical Design, and DFT teams to optimize performance, power, and area (PPA).
- Apply advanced OCV, SI, and IR-drop concepts to timing sign-off and closure strategies.
Requirements
Must-have technical skills and experience.
- Expert proficiency with sign-off tools (PrimeTime, Tempus).
- Deep experience with multi-mode multi-corner (MMMC) timing, OCV management, and full-chip STA signoff.
- Strong scripting skills (Tcl, Python, Perl, Shell) for automation and reporting.
- Proven experience using AI/plugins and data-mining to accelerate timing closure and reduce runtimes.
- Ability to analyze complex clock networks, cross-die timing paths, and coordinate ECOs at scale.
- Excellent problem-solving, communication, and cross-functional collaboration skills.
Nice-to-have:
- Experience with 2.5D/3D chiplet integration (CoWoS, HBM) and very large die implementations.
- Familiarity with infrastructure/cluster optimization for large-scale EDA runs.
Education Requirements
Bachelor’s degree in Electrical or Computer Engineering is specified. The posting also specifies 12+ years of hands-on ASIC STA and timing closure experience.
