Corelis Introduces QuadTAP/CFM High-speed Multi-TAP Boundary-scan System

Corelis QuadTAP/CFM four-channel JTAG hardware platform

Corelis introduced their QuadTAP/CFM four-channel JTAG hardware platform. The QuadTAP/CFM seamlessly integrates advanced boundary-scan test capabilities into Teradyne in-circuit testers. It is designed for use with Teradyne TestStation and GR228x series testers. The Corelis QuadTAP/CFM platform is a completely seamless and versatile hardware solution that meets multi-TAP JTAG testing requirements on existing Teradyne equipment.

The QuadTAP/CFM is a single slot Custom Functional Module (CFM) form factor board. It installs directly into one of four slots on a Teradyne Custom Function Board (CFB). Integration is simple and transparent. Once installed in the system, up to eight signals of the QuadTAP/CFM JTAG, GPIO, I2C, and SPI are available to test fixtures and the tester backplane.

Additional signals are made available using the included Expander modules which install into additional CFB slots. Integrated SPI and I2C programming features make the QuadTAP/CFM an ideal and universal solution for boundary-scan, JTAG embedded test, and in-system programming applications.
