Put the most powerful instrument on your board – the CPU – to work performing structural and functional diagnostics, debug routines and tests all in one pass.
Embedded in that CPU on your circuit board are the instruments that are critical for overcoming today’s design challenges. Given the complexity of board designs and chips, you need access to this on-chip technology to diagnose, debug and test your designs. One of the tools that makes up the ScanWorks platform for embedded instruments is Processor-Controlled Test (PCT). It takes advantage of the CPU’s debug port for access to the circuit board so it can perform board debug, device initialization, at-speed functional test with structural diagnostics and much more. PCT is just one of several ScanWorks tools which address every stage in a product’s life cycle.
With the PCT Manufacturing software, test operators with minimal training can apply structural and functional tests to circuit boards on the assembly line. The return on investment is very fast due to the lower costs for hardware, software and labor. Re-use of tests developed during prototype stages also keeps engineering costs down.
With embedded PCT, information about difficult-to-reproduce failures in the field can be captured for analysis.
With the PCT Development software, design or test engineers can debug prototypes using low-level control of the processor, as well as develop test and diagnostics tools for manufacturing and repair facilities.
The PCT Diagnostic & Repair software enables fast isolation of faults and the identification of their causes. Failed printed circuit boards coming off a manufacturing line or faulty product returned by a customer could be routed to a technician for diagnosis, repair and retest, transforming a liability into a revenue opportunity much sooner.
The ScanWorks platform for embedded instruments is supported by a wide variety of hardware controllers and accessories with which engineers can connect ScanWorks to their unit under test (UUT). Hardware is available for development, production and repair environments. The test platform required for ScanWorks is either a standard PC or a system with a built-in (embedded) JTAG controller.
