Engineer - PDN
ArmJob Title
Engineer - PDN
Role Summary
The Engineer - PDN will work within Arm's Solutions Engineering group on physical implementation and power-delivery network (PDN) analysis for SoC and CPU designs. The role focuses on implementation flows, timing and power optimization, physical verification closure and enabling partners to achieve high-quality silicon results.
Experience Level
Entry-level — typically 1–2 years of relevant ASIC implementation or physical design experience.
Responsibilities
Key responsibilities include:
- Perform synthesis, DFT, floorplanning, place-and-route (PnR), clock tree synthesis (CTS) and optimization for CPU cores, interconnect and blocks.
- Drive RTL-to-GDS closure for hard macros and full-chip builds.
- Analyze timing, area and power metrics and propose optimizations to improve design quality.
- Perform physical verification analysis (DRC/LVS/PERC/ERC) and layout edits for closure using tools such as Calibre.
- Analyze timing with PrimeTime and implement timing ECOs for closure.
- Collaborate with implementation and physical-IP RTL teams to drive analysis and optimization.
- Convert R&D concepts into practical implementation solutions and enable partners to achieve quality of results.
Requirements
Must-have skills and experience:
- 1–2 years of proven experience in ASIC implementation, physical design, STA and timing closure, structured clock tree design, PDN analysis, DFM and physical verification.
- Experience across top- and block-level synthesis, floorplanning, PnR, CTS, logical and physical optimization, timing closure and power analysis flows.
- Strong problem-solving and communication skills.
- Proven programming and scripting skills (examples: Tcl, Perl, Python, Make).
Nice-to-have:
- Familiarity with Arm-based SoC architectures.
- Experience with additional scripting/programming languages and data presentation tools (C/C++, JavaScript, R, Ruby, shell scripting, etc.).
- Knowledge of low-power techniques (power gating, voltage/frequency scaling), Verilog RTL design, ATPG or production test flows.
Education Requirements
Bachelor's or Master's degree (or equivalent) in Electrical Engineering, Computer Engineering, Computer Science or another relevant technical field; equivalent practical experience accepted.
