Applications of Logic Analyzers in Boundary scan testing (JTAG)

Overview

Boundary Scan Testing, commonly referred to as Joint Test Action Group (JTAG) testing, is a method used to test and debug digital integrated circuits (ICs), printed circuit boards (PCBs), and other electronic components. It provides a way to test the connectivity and functionality of various on-board digital components, such as chips, memory devices, and other digital logic elements.

Depending on specific features and functions, GAO Tek’s Logic analyzers are sometimes referred to as Digital Analyzers, Logic analyzers Testers, Signal Analyzers, Data Analyzers, State Analyzers, Event Analyzers, Timing Analyzers, Waveform Analyzers, Bitstream Analyzers, Protocol Analyzers

GAO Tek’s Logic analyzers have the following applications in Boundary scan testing (JTAG):

Signal Monitoring and Verification: GAO Tek’s Logic analyzers can capture and display digital signals from the boundary scan cells and other relevant pins of the devices under test. This allows engineers to verify the correctness of signal transitions, timing relationships, and protocol adherence, ensuring that the JTAG operations are executed accurately.
Fault Detection and Diagnosis: When a fault is detected during JTAG testing, a GAO Tek’s logic analyzer can be used to capture and analyze the relevant signals around the fault location. By examining the captured data, engineers can diagnose the root cause of the fault, whether it’s an open circuit, short circuit, or other connectivity issues.
Waveform Visualization: GAO Tek’s Logic analyzers provide waveform visualization, which helps engineers understand the signal behavior during JTAG operations. This can be particularly useful for debugging complex timing issues and identifying anomalies.
Protocol Analysis: JTAG follows a specific protocol for communication and control. GAO Tek’s Logic analyzers can decode and analyze the JTAG protocol, showing the sequence of instructions and data being exchanged between the test equipment and the devices under test. This assists in verifying the proper execution of JTAG commands.
Interactions with Other Circuitry: GAO Tek’s Logic analyzers can capture interactions between JTAG-enabled devices and other components on the PCB. This helps ensure that JTAG operations do not adversely affect the behavior of other digital circuitry.
Multi-Chip Testing: In systems with multiple JTAG-enabled devices, logic analyzers can monitor and correlate signals from different devices simultaneously. This is valuable for testing and debugging complex circuits with interconnected components.
Real-Time Observation: GAO Tek’s Logic analyzers provide real-time monitoring of signals during JTAG testing, enabling engineers to see how the circuit responds to various commands and data patterns in real-time.
Triggering and Event Capture: GAO Tek’s Logic analyzers can be configured to trigger specific conditions or events during JTAG testing. This allows engineers to capture specific sequences of signals for in-depth analysis and troubleshooting.
Data Integrity Verification: GAO Tek’s Logic analyzers can help verify the integrity of data transferred during JTAG testing, ensuring that the correct values are being shifted into and out of the boundary scan cells.
Automated Test Execution: Some GAO Tek’s logic analyzers offer integration with test automation frameworks, enabling the creation of test scripts that combine JTAG operations with logic analyzer data capture. This streamlines the testing process and facilitates efficient data analysis.
