Goepel electronic, vendor of JTAG/Boundary Scan solutions compliant with IEEE Std.1149.x, introduces new features de- signed specifically for parallel execution of VarioTAP processor emulation with the boundary scan software platform System Cascon. These new core func- tions enable the creation of massive parallel (Gang) test and programming applications through processor emulation with just a single boundary scan controller. VarioTAP is an adaptive stream- ing technology for JTAG TAP signals that allows flash devices to be programmed and processor emulation tests (PET) and boundary scan tests to be executed in combination within the same test program. The basis for the new features is the implementation of special synchronous streaming capabilities for multiple TAPs with same-type target processors, which allows a syn- chronized handling of emulation sequences that are normally executed asynchronously per unit under test (UUT). The number of identical, parallel addressable targets depends on the test system hardware in use. With the hardware platform Scanfles gang applications with up to 8 targets can be realized. Various test controllers are available, with interfaces such as USB 2.0, PCI, PCI Express, PXI, PXI Express, FireWire, and Gbit LAN, respectively. The new VarioTAP capabilities are especially important in medium and high volume production of boards that feature an MCU with embedded Flash. Such applications can now enjoy through- put improvements due to parallel execution on multiple identical boards, while at the same time allowing the combination of boundary scan tests, dynamic emulation tests, or in-system programming (ISP) of PLD.
