Goepel electronic has introduced a fully automatic program generator specifically for the dynamic test of on-board system-bus structures. The capability is part of the company's System Cascon boundary-scan software platform. The newly developed tools are based on Goepel's VarioTAP technology for functional emulation tests and enable complete automation of the test vector generation as well as for the error diagnostics.
“With the new tools, we raise the fusion of static boundary scan test and dynamic emulation test to a completely new level,” says Thomas Wenzel, managing director of the boundary-scan division of the Goepel electronic. “The high automation level and the independence of the tools from the target microprocessor completely relieve users from manual program code generation without flexibility limitations. Therefore, the entire process not only gets more productive but safer. The dynamic test coverage as well as the error diagnostic quality improve significantly.”
The core element of the new solution is an Automatic VarioTAP test program generator (AVTG) for bus devices. It is fully integrated in System Cascon and supports the same project database as any existing boundary scan modules. The AVTG recognizes the structural relations between the processor and the connected bus components and generates structural test vectors, which are later attached as emulation tests in real time to the target. It enables the dynamic test of resources connected to the processor, such as communication interfaces, bus bridge, digital I/O, analog I/O, and displays with deterministic fault coverage.
The generation of the test program is based on Caslan (the native Cascon language) source code and can be easily read to aid debugging. The generated test programs are compatible with all Goepel ScanBooster and ScanFlex JTAG/boundary-scan controllers, so no processor-specific pods are required.
The new emulation test tools are integrated as standard from System Cascon version 4.5 and are activated by the license manager. For users with a valid software maintenance contract the release is free. Cascon library models for bus devices can be provided by Goepel electronic or generated by the users themselves. At the moment, VarioTAP models are available for more than 200 processors from different vendors such as ARM, Atmel, Freescale, Intel, Marvell, NXP, Renesas, Texas Instruments, and STMicroelectronics. In cooperation with iSYSTEM, this range will be extended to more than 1000 processors.
