User Training for Design Rule Checks, Modularization, and Variant Validation

Initial Situation & Objective

In day-to-day engineering work, complex tool logics, varying interpretations of rules, and unclear error messages in DRC, EFC, and VTAT led to uncertainties. This directly impacted the quality of results, team efficiency, and release stability.

The goal of the project was to establish a shared, practice-oriented understanding of the tools used and to enable users to resolve issues independently and confidently.

Specifically, this meant:

consistent interpretation of rules and results
confident handling of typical error patterns
more efficient day-to-day work

Our Solutions

We developed and delivered a modular training concept that combined theory, hands-on practice, and direct exchange.

DRC Training: Structured Error Analysis, Rule Comprehension, and Best Practices
EFC Training: Tool Logic, Typical Inputs, HDBX Structures, and Troubleshooting
VTAT Training: Application in the QA Context, Interpretation of Results, and Integration into the Development Process
Interactive Q&A Sessions: Clarification of Project-Specific Questions and Practical Examples

Results & Added Value

The training resulted in measurable and sustainable improvements:

Reduced error rate in early development phases
More stable and faster releases
Greater transparency through improved tool understanding
More efficient troubleshooting without escalations
VTAT established as a recognized QA instrument within the development process
