CAMBRIDGE, UK Goepel electronic announced the development of a special model library for Freescale processor types MPC85xx to support its in-system 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, embedded or external Flash can be in-system programmed via the native processor function.
Furthermore, VarioTAP supports interlaced bus emulation tests (BET) and system emulation tests (SET) for extended JTAG/boundary scan functionality.
"By combining the powerful PowerQUICC III processor family from Freescale with our VarioTAP technology, users are now able to combine structural boundary scan tests with functional emulation tests for dynamic components as well as high-speed Flash programming on a unique platform," says Bettina Richter, Goepel electronic's marketing manager.
The VarioTAP IP-models for Freescale MPC85xx processors have been developed in cooperation with the company iSystem, recently affiliated into Goepel electronic's GATE partner program. They enable Flash programming and numerous emulation test functions.
The adaptive streaming technology of the test access port (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.
