Budgeting Python (must) Training

What this posting asks for

Level: Senior — The posting asks for 5+ years of experience.

Main responsibilities

• Hierarchical Physical Design
• Define and execute the hierarchical partitioning strategy: block boundaries, feedthroughs, pin placement, and budgeting across levels of hierarchy.
• Develop and maintain floorplans, power grids, and timing/physical budgets for large multi-block SoCs.
• Own the interface between block owners and top-level integration, including abstract (ILM/ETM) generation, boundary timing, and hierarchical ECO propagation.
• Manage die-to-die partitioning for 3D stacks – assign logic to tiers, plan hybrid-bond / µbump / TSV interfaces, and align inter-die floorplans.
• Block-level Implementation & Signoff
• Synthesis: Drive logic synthesis (constraints, DFT insertion, physical-aware synthesis), QoR analysis, and RTL-to-gate correlation.
• Floorplanning: Macro placement, power planning, congestion and timing feasibility, and pin/port optimization.
• Placement & Optimization: Standard-cell placement, timing-driven and congestion-driven optimization, useful-skew and multi-corner/multi-mode closure.
• CTS: Clock tree synthesis and clock distribution (including inter-die clocking for 3D), skew/latency balancing, and OCV/AOCV/POCV-aware clock closure.

Competencies an interviewer will look for

• Technical skill Core
  In the posting: “We are seeking a Senior Physical Design Engineer to own block-to-full-chip implementation and signoff on advanced-node, multi-die 3DIC products.” · “Debug convergence issues and drive root-cause analysis across timing, physical, and multi-physics domains.” · “BS/MS in Electrical/Computer Engineering (or equivalent) with 5+ years of physical design experience;”
  Show it by: Names the tools, languages or systems used and how; Explains a technical choice and its trade-off.
• Planning and organisation Core
  In the posting: “Manage die-to-die partitioning for 3D stacks – assign logic to tiers, plan hybrid-bond / µbump / TSV interfaces, and align inter-die floorplans.” · “Floorplanning: Macro placement, power planning, congestion and timing feasibility, and pin/port optimization.” · “Excellent medical, dental, and vision insurance through a PPO plan”
  Show it by: Shows how priorities were set when everything was urgent; Mentions deadlines met and how.
• Data and analysis Core
  In the posting: “Synthesis: Drive logic synthesis (constraints, DFT insertion, physical-aware synthesis), QoR analysis, and RTL-to-gate correlation.” · “Signoff: Static timing analysis (STA) across all corners/modes, physical verification (DRC/LVS/DFM), EM/IR (static and dynamic), and formal netlist equivalence.” · “analyze junction temperatures, hotspot coupling between tiers, and thermal-aware placement;”
  Show it by: Uses a number to describe the situation or the result; Explains what the data showed and what was done with it.
• Teamwork and collaboration Core
  In the posting: “Methodology & Collaboration” · “Partner with packaging, design, DFT, DV, and CAD teams to align die/package/system co-design.”
  Show it by: Says what they did inside a team, not only what 'we' did; Shows how a disagreement was handled.
• Ownership and accountability Supporting
  In the posting: “Own the interface between block owners and top-level integration, including abstract (ILM/ETM) generation, boundary timing, and hierarchical ECO propagation.”
  Show it by: Takes a task from start to finish without being chased; Owns a mistake and what was changed after it.
• Adaptability and learning Supporting
  In the posting: “Flexible time off *Temporary Employees & Interns excluded”
  Show it by: Describes learning something new quickly and using it; Shows a change of plan and how they adjusted.
• Attention to detail and quality Supporting
  In the posting: “Placement & Optimization: Standard-cell placement, timing-driven and congestion-driven optimization, useful-skew and multi-corner/multi-mode closure.”
  Show it by: Gives an example of an error caught before it caused harm; Names the check or standard they used.
