ScanExpress boundary-scan tools offer a powerful solution for testing and debugging complex printed circuit boards (PCBs). By leveraging the boundary-scan architecture defined by the IEEE 1149.1 standard, also known as JTAG, ScanExpress tools provide comprehensive access to individual components on a PCB, even those not directly accessible via traditional test probes. This non-intrusive testing method significantly enhances fault coverage, reduces test development time, and lowers manufacturing costs.
Understanding Boundary-Scan and Its Benefits
Boundary-scan technology utilizes dedicated test circuitry embedded within integrated circuits (ICs) on a PCB. These circuits, connected serially, form a boundary-scan chain that allows test data to be shifted in and out of each IC. ScanExpress tools communicate with these chains to perform various tests, including:
- Interconnect testing: Verifying the integrity of connections between components, such as shorts, opens, and incorrect wiring.
- Memory testing: Testing RAM and other memory devices for proper operation.
- Logic cluster testing: Verifying the functionality of groups of logic gates.
- In-system programming: Programming flash memories and other programmable devices while they are soldered onto the PCB.
