In-System Emulation Technology VarioTAP extended to Freescale ColdFire Architecture

The libraries, described as VarioTAP® models, are structured modularly as intelligent IP and enable a complete fusion of Boundary Scan test and JTAG emulation by employing the BDM debug interface. VarioTAP® covers various functions from on-chip Flash programming to emulation test on system level.

“In particular, customers in the field of industrial control have been asking for VarioTAP® support for the MCF5225x series.” Said Stefan Meissner, GOEPEL electronic’s spokesman. “In addition to supporting the architecture, we are continuously extending the provision of test and programming IP’s for Freescale processors.”

Users of the new VarioTAP® models are able to combine structural Boundary Scan tests with functional emulation tests for dynamic components as well as high-speed programming on one platform in just one run. The Boundary Scan or BDM signals are controlled by the recently introduced new SCANFLEX® hardware TIC020 with programmable Multi Bus interface.
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 is 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 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. 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®.
