Optimize your designs with Test, Validation, and DfT

In an environment with stringent requirements for performance and security, ensuring the testability and reliability of electronic boards becomes a major challenge.

An effective testing and validation strategy, combined with a DfT (Design for Test) approach, allows for integrating testability from the design phase and detecting failures as early as possible, thereby optimizing product quality and durability. At LACROIX, we support our clients throughout the lifecycle of their electronic boards to ensure optimal quality, reduce time-to-market, and lower the overall project cost.

The importance of a comprehensive Testing Strategy for electronic boards

Testing is a crucial step in the development cycle of an electronic board. A well-defined strategy enables identifying anomalies from the earliest project phases, thus avoiding high correction costs during production and ensuring the quality of delivered products.

Our approach integrates:

Defining exhaustive test plans

in-circuit tests, functional tests, boundary scan, memory tests

Test
automation

to ensure optimal coverage and result repeatability

Implementation of test environments

for continuous validation at each development stage

Measuring specific KPIs

to track progress and optimize test performance

Validation and non-regression: Ensuring quality throughout the lifecycle

At LACROIX, we implement rigorous validation processes to ensure the proper functioning of electronic boards throughout their lifecycle. Our non-regression tests verify that no new revision compromises existing functionalities.

Our key steps:

  • Systematic execution of non-regression tests with each design modification
  • Analysis of technical debt to identify and limit vulnerability points
  • Performance validation under real-world conditions
  • Implementation of continuous improvement for validation protocols

DfT: Designing for Testability from the Start

Design for Test (DfT) is an engineering methodology that integrates testability from the earliest phases of electronic board design. This approach optimizes testing processes, reduces costs, and accelerates time-to-market.

Our experts implement DfT best practices:

  • Integration of JTAG and boundary scan test architectures to improve test coverage
  • Design of specific test points to facilitate in-circuit testing (ICT)
  • Implementation of built-in self-test (BIST) functions for field validation
  • Optimization of critical component and interface testability
  • Consideration of test constraints from the electronic schematic design phase
