Boundary Scan (IEEE Std. 1149.x) is a technology for embedded access of IC pins by way of integrated scan cells. They form a shift register controlled via the Test Access Port (TAP). The principle was developed as an alternative to In-Circuit Test (ICT) to avoid the utilisation of nail probe contact.

Boundary Scan is part of the so called Embedded System Access (ESA) technologies, containing procedures such as Chip Embedded Instruments, Processor Emulation Test, In-System Programming or Core Assisted Programming. ESA technologies are currently the most modern strategies for validation, test and debug as well as programming of complex boards and systems. They can be applied throughout the entire product life cycle, enabling enhanced test coverage at reduced costs.

Chip embedded Instruments are permanently integrated or temporarily implemented test and measurement functions (T&M) in an integrated circuit. Virtually, they are the counterpart to external T&M instruments as they don’t require invasive contacting by means of probes or nails. Hence, the problem of signal distortion in high-speed designs by parasitic contacting effects is omitted. Chip embedded Instruments are part of the so called Embedded System Access (ESA) technologies, featuring methods such as Boundary Scan, Processor Emulation Test, in-system programming or Core assisted Programming.

ChipVORX is an IP-based technology for implementation, access and control of Chip embedded Instruments via IEEE Std. 1149.x/JTAG. It also supports FPGA embedded instruments in the form of softcores. The ChipVORX library currently contains more than 300 different test and measurement instruments for all leading FPGA platforms. Some of these instruments are frequency meters, high-speed Flash programmer as well as IP for at-speed access test of dynamic RAM devices. The usage of ChipVORX^® requires neither expert background knowledge nor specific FPGA tools or continuous IP adjustments.

Basically, ScanVision^™ consists of the three elements Layout Visualizer, Schematic Visualizer and Virtual Schematic Visualizer. All components are integral parts of the Boundary Scan system software SYSTEM CASCON^™, using a consistent project data base. This data base is generated by importing individual design data and interconnection referencing. For this purpose, appropriate tools are the CASCON Board Merger™ and CASCON Component Explorer^™.

Using this information provides opportunities for interactive cross-probing between schematic and layout, selective labelling of pins, components and circuits, as well as tracking of signal paths via multiple boards with dynamic switching. That enables operations such as test coverage analysis, hardware debugging or graphical fault display far above the board boundaries up to system level.

The enhanced ScanVision tools are integrated as standard starting from SYSTEM CASCON™ version 4.6.1 and are activated by the licence manager like the system software. For customers with a valid maintenance contract the new features are free of charge. SYSTEM CASCON™ is a professional JTAG/Boundary Scan development environment, developed by GOEPEL electronic currently with 45 completely integrated ISP, test, and debug tools for the support of all Embedded System Access technologies.
