In-System Emulation Technology VarioTAP meets TigerSHARC DSP from Analog Devices

“In particular, customers in the fields of Automotive, Audio and Defence asked us to support TigerSHARC DSP. We are now able to support these projects extensively” says Steffen Köhler, Team Manager in GOEPEL electronic’s Emulation Group within the Boundary Scan product division. “By combining functional at-speed tests with conventional Boundary Scan procedures, users achieve considerably higher fault coverage and a higher diagnostic quality, which results in major cost savings in the production process.”

The VarioTAP® IP models for TigerSHARC DSP has been developed in close cooperation with the Estonian Company Testonica, and enables Flash programming as well as numerous emulation test functions.

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. The number of Taps’ is effectively unlimited by utilising the hardware platform SCANFLEX® for instance, up to eight Taps’ can be controlled independent from and simultaneously to other I/O resources. In addition to dynamic tests of externally connected components such as RAM or I/O resources, the IP functions for bus emulation and system emulation enable the functional testing of on-chip resources as well as the execution of program codes defined by the customer.

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 extensive OEM cooperation with all 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 4.5.4, and are activated by the licence manager in the system software. SYSTEM CASCON™ is a professional JTAG/Boundary Scan development environment, developed by GOEPEL electronic with currently 45 completely integrated ISP, test, and debug tools. Regarding the hardware, VarioTAP® is completely supported by the controllers of the SCANBOOSTER™ family, as well as by the hardware platform SCANFLEX®.
