Corelis Introduces PXIe-1149.1/4E™

High-Performance 4-TAP PXI Express JTAG Controller

Corelis, the leading supplier of high-performance boundary-scan test and measurement software and hardware, announced the release of its High-Performance 4-TAP PXI Express JTAG Controller.

Boundary-scan has proven itself time and again to be a truly versatile interface for structural test, embedded functional test, built-in self-test (BIST), software debug, and in-system programming. Supporting such diverse applications requires a controller with high-performance specifications and diverse features.

The PXIe-1149.1/4E is a high-performance, multi-feature boundary-scan controller for multi-TAP and concurrent JTAG test and in-system programming. Featuring a high-speed PXI Express (PXIe) interface with four independent and configurable Test Access Ports (TAPs) along with direct serial programming capability, the PXIe- 1149.1/4E enables of Boundary-scan integration with PXIe systems.

The Corelis PXIe-1149.1/4E is fully compliant with the IEEE Standard 1149.1 (commonly referred to as JTAG) for test access. Based on the Corelis IEEE- 1149.1/4E 4-TAP architecture, the PXIe card can be installed in a PXIe chassis to provide up to four test access port (TAP) connections on any JTAG-based target system. Support for concurrent (Gang) test execution and in-system programming, configurable pinout, and integrated serial interfaces on each TAP interface make the PXIe-1149.1/4E ideal for multi-TAP and high-volume JTAG and serial bus-programming integration.

For applications that require a low-level interface or integration with third-party software, Corelis offers a Scan Function Library (SFL). The SFL is provided as a DLL for Microsoft Windows and provides all functions necessary to operate the JTAG port to send and receive JTAG instructions and data from the target system. The SFL can be incorporated in custom application software or integrated with third-party systems such as National Instruments LabVIEW, National Instruments TestStand, and Keysight VEE.
