DFT & BSCAN: Design and Test in Perfect Synergy
At GEB Enterprise, we believe Design for Test (DFT) and Boundary Scan (BSCAN) are not just test strategies — they’re core principles of a design philosophy that prioritizes quality, reliability, and transparency from the very first step.
An effective and meaningful BSCAN test is only possible when the board has been designed with DFT in mind from the beginning. When testability is considered too late — after prototyping or even during production — opportunities for structural improvements are drastically reduced. The result is often:
-Limited fault coverage
-Poor diagnostic resolution
-Longer test and programming times
-Higher risk of costly rework and delays

DFT & BSCAN: Design and Test in Perfect Synergy
At GEB, DFT is not an afterthought — it’s part of our DNA.
Through our concurrent engineering approach, DFT analysis runs in parallel with board design. This ensures that testability constraints are addressed from day one, enabling optimal placement of scan chains, test points, and programming interfaces.
By embedding DFT directly into the design cycle, we build robust, cost-effective BSCAN test structures that are ready for real-world validation.

DFT for External Projects
Our expertise is also available for third-party designs, with flexible collaboration models:
-Early Collaboration (ideal)
We work alongside your design team from the early stages. This allows us to provide real-time feedback, significantly improving test coverage and simplifying downstream validation.
-First Prototype Analysis (practical)
If the design is already in prototyping, we can still perform a full DFT/BSCAN review before mass production. While structural changes may be limited, we focus on risk containment, test optimization, and validation efficiency.

JTAG: A Strategic Asset in Prototype Validation
In modern electronics, JTAG (Boundary Scan) is much more than a functional check — it’s a strategic enabler that accelerates prototype testing and improves system reliability from the earliest phases.
With its structural, scan-chain-based method, JTAG makes it possible to detect manufacturing defects such as:
-Cold or missing solder joints
-Floating or shorted pins
-Misplaced or incorrect components
But JTAG goes even further. During development, it allows engineers to verify connectivity between the FPGA and external peripherals — regardless of the VHDL code’s state or internal logic implementation.
This means you can:
-Detect incorrect pin assignments early
-Identify HDL-related anomalies before functional test failures occur
-Isolate hardware/firmware issues quickly, reducing time-consuming debug loops
By integrating JTAG into the prototyping phase, GEB helps reduce development time, increase design quality, and ensure a smoother, faster path to production.
