Corelis Introduces Support for Xilinx™ J Drive In-System Configuration Engine

Adding J Drive In-system Configuration (ISC) support for IEEE-STD-1532 compliant devices,
provides Corelis’ boundary-scan users with the convenience of  programming devices in-system
using Corelis’ boundary-scan test and  in-system programming tools.

Cerritos, CA, November 1, 2001 – Corelis Inc., today introduced support for the Xilinx J Drive implementation of the proposed  IEEE Std 1532 for In-System Configuration. The J Drive programming engine can be used to program in-system IEEE Std 1532 compliant devices such as Xilinx’ XC18V00, Virtex™, and Virtex-E.

All Xilinx FPGAs and CPLDs that support the IEEE Std 1532 in-system configuration feature, can now be programmed directly using Corelis ScanPlus test systems. This powerful upgrade adds value by reducing device handling costs, thus reducing time to market, and also provides remote upgradeability and testing.  Users can now include J Drive files in Corelis’ powerful test executive, ScanPlus RunnerTM , and program IEEE Std 1532 compliant devices in-system.

“Corelis’ ScanPlus Runner can now program IEEE Std 1532 compliant devices using J Drive files that were directly generated by the silicon vendors or other third party development tools” said Steven Hartman, Marketing Manager for Corelis’ ScanPlus product line. Mr. Hartman added: “J Drive provides the added benefits of concurrent programming of multiple devices, and separate data and algorithm files making updates faster and easier.  Xilinx’ commitment to J Drive adds significant  value and benefit to IEEE Std 1149.1 and the proposed IEEE Std 1532.”

Anthony Le, Product Marketing Manager for Xilinx said “We are very pleased that Corelis has added J Drive support to its already powerful boundary-scan and in-system programming tools. It allows Corelis users to standardize in-system configuration across all Xilinx’ and other Programmable devices manufacturers, and allows newly released devices to be quickly supported.”

What is J Drive?

The J Drive™ programming engine provides immediate and direct in-system configuration (ISC) support for IEEE Std 1532 programmable logic devices (PLDs). To configure an in-system device, the programming engine uses the configuration algorithm information from the proposed1532 Boundary-Scan Description Language (BSDL) file to apply configuration data from the 1532 data file through the IEEE Std 1149.1 test access port (TAP). The J Drive programming engine can be used for the following Xilinx families: XC18V00, Virtex™, and Virtex-E.

What is IEEE Std 1532?

The IEEE Std 1532 standard is a formal extension to the IEEE Std 1149.1b-1994 (also known as JTAG) for programmable devices. This standard defines the three items required to configure in-system programmable logic devices: Device architectural components for configuration, Algorithm description framework, and Configuration data file. The proposed standard is undergoing final changes and is expected to be approved by January 2002.

Price, platform and availability

Corelis support of J Drive is shipping now and is offered at no charge to ScanPlus users who have a maintenance contract.
