Physical Design Engineer (PnR)
About The Role
Avicena is developing high-speed parallel optical links built from arrays of microLED transmitters and photodetector receivers. We are looking for a physical design engineer to implement and close digital blocks and top-level partitions of our mixed-signal ASIC. You will work with the PnR lead to take designs from netlist to clean signoff.
Key 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.
Required
- 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.
- Mixed-signal top-level integration.
- IR/EM analysis and fixing.
- DFT-aware implementation, such as scan chain reordering.
- Hierarchical implementation.
- Detail-oriented: closes issues completely.
- Learner: picks up new flows quickly.
- Collaboration: works closely with the PnR lead and design teams.
- Ownership: delivers assigned blocks on schedule.
