Emulation Technology to support ARM’s Serial Wire Debug (SWD) Interfaces

06 October 2010 - GÖPEL electronic announces the extension of the innovative emulation technology VarioTAP to support ARM’s Serial Wire Debug (SWD) interfaces. VarioTAP’s functional range includes on-chip programming up to emulation tests at system level, and is based on processor specific library models in the form of software IP. The new VarioTAP models’ first implementation covers the ultra low energy MCU of Energy Micro’s EFM32 Gecko series with Cortex-M3 core.

“Perspectively, we expect a wider spread of low pin count test and debug interfaces. The now available VarioTAP support of ARM’s Serial Wire Debug accesses is not only another strategically important 2-wire interface but increases our solutions’ future reliability“, says Thomas Wenzel, Managing Director of GOEPEL electronic’s JTAG Boundary Scan Division. “Combining Energy Micro’s innovative MCU with our unique VarioTAP technology, users are able to validate, test and program in particular power-saving products for applications such as Smart Metering, Medical Devices, Security and additional energy intensive markets even faster.”

Users of the new VarioTAP® models for the EFM32 Gecko series are now able to initially execute the functional emulation test for all board components and subsequently program embedded Flash. This procedure takes only few seconds. It is executed in a consistent run, provides extremely high fault coverage and requires only one hardware platform.

The Boundary Scan signals or SWD signals are consistently controlled by the recently introduced SCANFLEX hardware TIC020 with programmable multi-bus interface for JTAG and non JTAG architectures.

The adaptive streaming technology of the TAP signals allows emulation tests to be executed in parallel or interactively with Boundary Scan tests within a test program, whereby the number of Taps’ is unlimited. A multitude of possible configurations including multi processor and Gang applications are supported.

The use of VarioTAP does not require expert background knowledge, additional development tools or processor-specific pods, which makes the handling easy and uncomplicated.

Due to the OEM cooperation with all the leading vendors of In-Circuit Testers (ICT), Manufacturing Defect Analysers (MDA), Flying Probe Testers (FPT) and Functionality Testers (FT), the new solution is available for production with immediate effect.

The new VarioTAP IP models are supported as standard starting from SYSTEM CASCON version 4.5.3, and are activated by the licence manager like the system software..
