Goepel Electronic GmbH (Jena, Germany) has developed a dedicated model library for the Freescale MCF5225x microcontroller with ColdFire V2 architecture to support its VarioTAP emulation technology.
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.
Users of the 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 one run.
The boundary scan or BDM signals are controlled by the recently introduced 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 number of configurations including multi processor and 'gang' applications is supported.
Goepel says VarioTAP does not require expert background knowledge, additional development tools or processor-specific pods, which makes the handling easy and uncomplicated.
The VarioTAP IP models are supported as standard starting from SYSTEM CASCON version 4.5.3, and are activated by the licence manager. SYSTEM CASCON is a JTAG/Boundary Scan development environment, developed by GOEPEL electronic with currently 45 completely integrated ISP, test, and debug tools.
