In modern semiconductor design, performance and reliability are not just about logic and timing—they also depend on how efficiently power is delivered across the chip. That’s where Power Delivery Network (PDN) design plays a critical role.

          At Avecas, we specialize in end-to-end PDN design services for advanced nodes and complex SoCs. Our approach ensures robust power integrity, minimal IR drop, and noise resilience—helping your chip achieve first-pass success without compromising performance, power, or area.

Avecas PDN Design Services

Our PDN services cover the complete flow from architecture to signoff, ensuring reliable power integrity at every stage.

1. PDN Architecture & Planning

• Defining power grid topologies for core, IO, and analog domains.

• Balancing metal layer usage to optimize performance and routability.

• Early IR drop budget allocation for better downstream closure.

2. IR Drop Analysis & Optimization

• Static and dynamic IR drop analysis across corners and activity profiles.

• Identifying hotspots and redistributing power for uniform delivery.

• Strengthening local power grids without excessive area overhead.

3. Electromigration (EM) Checks

• Current density analysis across power rails and vias.

• Implementing design strategies to extend product lifetime.

• Ensuring compliance with foundry EM reliability guidelines.

4. Decoupling Capacitor (Decap) Insertion

• Strategic placement of decaps to minimize supply noise.

• Optimizing trade-offs between leakage, area, and noise reduction.

5. PDN Signoff & Verification

• Using industry-standard tools (Ansys RedHawk, Voltus, Totem) for signoff.

• Full-chip validation across multiple modes and corners.

• Reporting and closure support to ensure tape-out readiness.
