Physical Design Engineer (PnR)

Avicena Tech; Sunnyvale (CA); On-site; USD 140,000 - 190,000; Full time

Job summary

Avicena is seeking a Physical Design Engineer (PnR) in Sunnyvale, CA to implement and close digital blocks and top-level partitions of a mixed-signal ASIC. You will work with the PnR lead to take designs from netlist to clean signoff.

Ideal candidates have hands-on experience with Cadence Innovus or Synopsys ICC2/Fusion Compiler, and STA tools such as Tempus or PrimeTime, plus physical verification with Calibre or Pegasus on FinFET flows.

Qualifications

• BS or MS in Electrical or Computer Engineering with 3+ years of ASIC physical design.
• Hands-on experience with Cadence Innovus or Synopsys ICC2/Fusion Compiler, and STA with Tempus or PrimeTime.
• Physical verification with Calibre or Pegasus.
• FinFET implementation experience.
• Tcl and Python scripting.

Responsibilities

• Run synthesis, floorplanning, placement, clock tree synthesis and routing for blocks and partitions.
• Close timing across modes and corners, and implement ECOs.
• Run signoff checks: STA, IR drop and EM, physical verification and logical equivalence.
• Integrate analog macros and repeated arrays following the macro handoff checklist.
• Maintain and improve implementation scripts.
• Support tapeout and post-tapeout ECOs.
