Goepel - Intelligent Tools for Boundary Scan:

What is Boundary Scan?
JTAG/Boundary Scan is probably the most ingenious test process, which like ICT, tests within the circuit and detects structural fault locations by setting thousands of test points - even under BGAs - with only four test bus lines.
Boundary Scan essentially means “testing at the periphery (boundaries) of a circuit”.
In addition to the core logic and the test points, an IC (Integrated Circuit) also features some test control logic. The test points are integrated between the core logic and the physical pins of the IC. This special IC architecture and the test bus connections among each chip are preconditions for the use of Boundary Scan. If they are met the prediction of Boundary Scan is possible

  • Test particular components
  • Test the connections among the ICs on the board
  • Test the function of complete boards under operating conditions

Not all components on the board have to be testable in order to use the Boundary Scan philosophy. Even if only one component meets the Boundary Scan requirement, Boundary Scan can be used for certain test applications. Please ask us to run a testability analysis on your boards to show that there are thousands of components that can be tested with Boundary Scan.
Unlike other test access methodologies, Boundary Scan can be utilised from the beginning to the end of the production of a PCB for the following applications:

  • Testing
  • Design verification
  • In-system programming
  • Debugging
  • Emulation

Advantages of the JTAG/Boundary Scan technology:

  • Usable throughout the entire product life cycle
  • No mechanical access necessary – while still offering very high test coverage
  • Accelerates development of new products - reduced time to market
  • Test program generation in a short time - fast turnaround, e.g. for design changes

The handling of updates and upgrades is extremely simple, and problems due to incompatible tools are prevented. Software packages designed for laboratory, production, and field service are available in various performance classes (Editions) as Development Stations (DS) and Test/Execution Stations (TS/ES).

Pure Insystem Programming (ISP) applications can be realised with [CASCON POLARIS™] Editions, while [CASCON GALAXY®] supports both ISP and test procedures. The extensive CASCON Application Programming Interface (CAPI) enables powerful integrations. Floating Licenses provide extreme efficiency with Multi-Seat and Multi-Tooling capabilities.

Fusion of JTAG Emulation and Boundary Scan

VarioTAP is a revolutionary technology for pattern streaming on TAP (Test Access Port) signals compliant with IEEE Std. 1149.1. The technology utilizes on-chip emulation resources accessible in many micro-processors and micro-controllers through a IEEE 1149.1 compatible JTAG Port. The VarioTAP principle was specifically developed for the integrated Boundary Scan software, SYSTEM CASCON™, and enables the complete fusion of Emulation tools with test and In-System-Programming (ISP) applications.
The VarioTAP specific adaptive streaming showcases the dynamic synthesis of Emulation vectors and Boundary Scan vectors, supporting new test strategies such as Interlaced JTAG/Boundary Scan Tests and In-System Emulation Test / ISP.

Boundary Scan Controller overview:

SCANFLEX® hardware systems are controlled through a JTAG/Boundary Scan Controller. This controller is responsible for simultaneous generation and dynamic distribution of serial patterns, parallel patterns, and control sequences, supporting three standard SFX and SFX/LS Interfaces. SCANFLEX® Boundary Scan Controllers from GÖPEL electronic are available in three performance classes (A, B, and C). A main difference between these classes is the implemented Boundary Scan vector memory architecture. B- and C-type controllers feature the patented SPACE™ Architecture for advanced vector handling. The HYSCAN™ feature, available with all SCANFLEX® Controllers, provides a means to synchronize serial JTAG/Boundary Scan vectors and parallel I/O vectors.

As front-end, SCANFLEX® hardware systems use TAP-Transceiver modules. These modules are connected to the controller with the SFX cable (available in 2m/6ft, 5m/15ft, and 10m/33ft lengths). TAP Transceiver modules convert the data coming from the controller into respective operations of the built-in or added-on resources. TAP signals are provided through interchangeable TAP Interface Cards (TIC), allowing a nearly infinite range of front-end adaptations for various signal types, signal conditioning, and integration environments, including custom specific variants. SCANFLEX®TAP Transceivers as well as in rack-mountable housings, and they can be adapted to custom specifications. As a standard configuration, TAP Transceivers also include analog and digital I/O resources, typically at least one SFX I/O slot, and one additional SFX/LS interface, providing ample of resources for extended Boundary Scan test solutions.

The third major component in a SCANFLEX® hardware system is the optional I/O Module. These I/O modules are controlled independently from any other resources in the system through the SFX/LS interface. If the number of required SCANFLEX I/O Modules is very small (only 1 to 2 modules needed) the modules can be plugged directly onto the TAP-Transceiver, eliminating any additional cabling. Alternatively, I/O modules can be put into SCANFLEX Carriers, connected to the Controller or the TAP Transceiver through a SFX/LS cable (0.5m/1.5ft, 1m/3ft, 3m/10ft, or 5m/15ft). SCANFLEX® I/O Modules are used to extend the performance and capabilities of the Boundary Scan system with additional test instruments and programming resources, highly modular and scalable to match any specific test/ISP application. Custom specific modifications of standard modules and development of custom modules are offered through GÖPEL Electronic’s engineering services.
