In-System Emulation Technology supports Intel XScale Architecture
GOEPEL electronic has developed a dedicated model library for the XScale processors PXA2xx and PXA3xx that supports the innovative emulation technology VarioTAP. The libraries, described as VarioTAP models, are structured modularly as intelligent IP and enable a complete fusion of Boundary Scan test and JTAG emulation. Employing this technology, frequently used NAND flash can be in-system programmed with the help of the processor function. Furthermore, VarioTAP® supports interlaced Bus Emulation Tests (BET) and System Emulation Tests (SET) for extended JTAG/Boundary Scan functionality.
“TDue to the improved multi functionality of our JTAG/Boundary Scan platform, the users are able, e.g. to achieve a significantly higher test depth and can handle high speed flash programming with the same instruments. Thus the handling is easier and additional programmers are no longer needed.
The VarioTAP® IP-models for the XScale processors support all possible scan chain configurations, even multi-processor applications and scan router implementations. The adaptive streaming technology of the Tap signals allows emulation tests to be carried out in parallel or interactively to Boundary Scan tests within a test program.
In the flash programming both NOR and NAND flash are supported, whereas the so-called bad block handling can be realised in a standardised or customised version.
The use of VarioTAP® does not require neither expert background knowledge, nor additional development tools or processor-specific pods, which makes the handling easy and uncomplicated.
Due to the OEM cooperation with all leading vendors of In-Circuit Testers (ICT), Manufacturing Defect Analysers (MDA), Flying Probe Testers (FPT) and Functionality Testers (FCT), the new solution is available for production with immediate effect.
The new VarioTAP® IP-models are supported beginning with SYSTEM CASCON™ version 4.4.2 and are activated by the licence manager like the system software. SYSTEM CASCON™ is a special JTAG/Boundary Scan development environment designed by GOEPEL electronic with currently 38 completely integrated ISP, test and debug tools. In regard to hardware, VarioTAP® is supported by the controllers of the ScanBooster® series and the hardware platform SCANFLEX®.
