Principal Design Engineer
Cadence Design SystemsJob Title
Principal Design Engineer
Role Summary
Responsible for IR/EM signoff and power‑delivery network (PDN) optimization for advanced process nodes. Works with place-and-route, verification, and cross‑functional teams to ensure chip- and block-level power‑grid integrity during signoff.
Experience Level
Senior — 7 to 15 years of relevant experience in IR/EM/PDN signoff.
Responsibilities
Primary responsibilities include power-integrity analysis, driving fixes during signoff, and automation to improve efficiency.
- Perform static and dynamic IR‑drop and EM analysis using tools such as Voltus and RedHawk‑SC.
- Drive IR/EM fixes during PnR and physical verification signoff cycles.
- Optimize full‑chip and block‑level PDN, including PG mesh and RDL structures.
- Develop automation scripts (TCL, Python, Perl, Shell) to improve signoff efficiency and reduce turnaround time.
- Collaborate with layout, timing, and verification teams to resolve IR hotspots, EM violations, and PG bottlenecks.
Requirements
Must-have skills and experience.
- 7+ years of IR/EM/PDN signoff experience targeting advanced nodes (7nm → 3nm).
- Hands‑on experience with Voltus and RedHawk‑SC; familiarity with Innovus or ICC2 signoff environments.
- Strong scripting and automation skills (TCL, Python, Perl, Shell).
- Practical understanding of placement, routing, congestion, timing ECOs and their impact on power‑grid integrity.
- Experience driving fixes during PnR and PV signoff cycles and working with cross‑functional teams.
Education Requirements
BE / BTech / ME / MTech or equivalent engineering degree.
