Topology-Driven ESD Reliability Sign-off Architecture

Calibre PERC LDL as a Structural Reliability Firewall for TVS & ESD Design

System Architecture Overview

Layout Geometry (DRC) Connectivity (LVS) Silicon ESD Qualification Topology-Aware LDL Layer Discharge Path + Resistance Analysis Voltage-Aware & Cross-Domain Checks Robust Structural Sign-off

Project Context

In advanced SoC designs, ESD robustness depends not only on spacing and connectivity but also on resistance balance, discharge topology, and voltage-aware structural integrity.

Traditional sign-off validates correctness. LDL validates robustness before silicon stress testing.

Architectural Layers Explained

1. Geometry Layer (DRC)

2. Connectivity Layer (LVS)

3. LDL Topology Layer

4. Structural Reliability Sign-off

LDL functions as a structural firewall between layout completion and silicon ESD qualification.

Concrete Impact

Strategic Positioning

LDL transforms ESD verification from reactive failure analysis to proactive structural robustness engineering.

For high-voltage TVS and advanced nodes, topology-driven verification is a competitive reliability enabler.
