The Software concept

JTAG/Boundary Scan Software

The quality of a JTAG/Boundary Scan system is significantly determined by the performance and architecture of the used software.

In 1991 GOEPEL electronic has been developing an integrated Boundary Scan software development environment named SYSTEM CASCON.

Since then the uniqueness of the Boundary Scan workbench has been continuously expanded through the integration of new intelligent tools, along with innovative system extensions and improvements of the user interface.

Software updates are available via our customer web site GENESIS.

To perfectly address the needs of development, production and customer service, the software packages are available in dedicated performance classes as Development Stations (DS) and Test/Execution Stations (TS/ES). In-system-programming (ISP) tasks can be executed with CASCON POLARIS editions. The CASCON GALAXY version supports ISP and test methods.

The right tools for your application

VarioTAP by GOEPEL electronic is a technology for the fusion of Boundary Scan and Processor Emulation Test. This comprehensive suite bridges the gap towards achieving higher testing dynamics and also enables synchronisation with external I/O channels.

JEDOS (JTAG Embedded Diagnostics Operating System)

Chip-embedded instruments can prevent the problems with access points prevalent in traditional external instruments, while SYSTEM CASCON – by virtue of ChipVORX® technology and open software interfaces – is able to simultaneously access and control both classes. This ability greatly improves the capacity and test coverage of the entire system.

Tool Suite for Functional I/O Test

In addition to structural tests, SYSTEM CASCON also offers tools for functional testing. Here, too, CASLAN multipurpose control language is a key feature. To generate tests, one can either import simulation vectors in IEEE 1445 format, or resort to behavior models in the CASCON library. Selected PXI or SCANFLEX modules by GOEPEL electronic, which can generate the vectors dynamically, can be used as external I/O drivers.

This comprehensive suite contains powerful ATPG tools (automatic test program generation) that generate de-buggable CASLAN source code and can also integrate external I/O channels. The PFD modules (pin failure diagnostics) ensure clear error messages.
