GOEPEL electronic has uncloaked special model libraries for the first Fujitsu Graphical Display Controllers (GDC) of the MB86R0x Jade series and MB86R1x Emerald series to support the innovative emulation technology VarioTAP. The libraries, described as VarioTAP models, enable the flexible execution of processor emulation tests using the native debug interface. On this basis, hardware verification and test, as well as flash memory programming are possible without specific firmware, stated the company.

The Fujitsu MB86Rxx controllers provide superior performance for 'embedded automotive graphics solutions' such as navigation systems, visual dashboards or head-up displays, noted GOEPEL. The Jade series (MB86R0x) is controlled by an ARM9 processor, the heart of the Emerald series (MB86R1x) is an ARM Cortex A9 core. All GDC are integrated in a BGA housing, featuring numerous complex analogue and digital peripheral units incl. multiple video interfaces, a DDR RAM interface and an external flash interface.

The goal of VarioTAP is to provide appropriate tools for test, hardware debugging, flash programming as well as design validation after chip mounting with minimal access efforts.

VarioTAP enables the reconfiguration of the integrated processor into a native design embedded test and programming controller via the JTAG Debug port. In addition to Boundary Scan (IEEE 1149.x), this test approach, commonly known as Processor Emulation Test (PET) is currently the most modern method in the area of Embedded System Access (ESA) technologies. It enables the functional at-speed test of all peripheral interfaces. The execution of customer-specific software IP is also easily possible.

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

The VarioTAP IP models are supported in the development and execution software CASCON GALAXY starting from version 4.6.1, and are activated by the licence manager in the system software. CASCON GALAXY is a professional JTAG/boundary scan development environment, developed by GOEPEL electronic currently with 45 completely integrated ISP, test and debug tools. The utilisation of the respective VarioTAP models is free of charge for existent customers with valid software maintenance contracts.
