A new module in the boundary scan hardware platform Scanflex, SFX1149.4, provides resources for the test of analog circuits based on the IEEE Std. 1149.4.
 
“We have discussed the subject of 1149.4 frequently at technology events such as our worldwide Boundary Scan Days. This has enabled us now to introduce the first JTAG/Boundary Scan benchtop system for dot1/dot4 mixed-signal applications, just in time to support customer projects entering the prototyping stage,” said Thomas Wenzel, director of the business unit boundary scan.
 
The module provides one complete dot4 test bus (AT1, AT2) and can be plugged directly onto an SFX TAP transceiver. To support applications with multiple dot4 test busses, several modules can be integrated in a SFX-Carrier. The module provides advanced functions for R, L and C measurements, and the generation and measurement of AC and DC signals with programmability in voltage, current and frequency. Provides a ramp function coupled with a programmable digitizer to digitally record response signals.
 
Is fully supported in software System Cascon v. 4.3, including the automated recognition of the instrument through the AutoDetect feature. The Cascon Application Programming Interface (CAPI) enables integration in other test systems, also providing access to the dot4 functions and measurements from external control software.
