VarioTAP®

 

VarioTAP^® concept

VarioTAP is a revolutionary technology for pattern streaming on TAP (Test Access Port) signals compliant with IEEE Std. 1149.1. The technology utilizes on-chip emulation resources accessible in many micro-processors and micro-controllers through a IEEE 1149.1 compatible JTAG Port. The VarioTAP principle was specifically developed for the integrated Boundary Scan software, SYSTEM CASCON™, and enables the complete fusion of Emulation tools with test and In-System-Programming (ISP) applications.

The VarioTAP specific adaptive streaming showcases the dynamic synthesis of Emulation vectors and Boundary Scan vectors, supporting new test strategies such as Interlaced JTAG/Boundary Scan Tests and In-System Emulation Test / ISP.
