Correction before hardware
XJTAG has developed a testing tool in collaboration with PCB EDA vendors Altium, Cadence, Mentor Graphics and Zuken. The result is DFT Assistant, enabling early correction of ‘Design For Test’ errors before any hardware is produced.
Engineers can for the first time proactively validate test access and correct JTAG problems at the design stage, helping to prevent costly re-spins and project delays. The tool provides a level of automation in checking that the chain(s) are connected and terminated correctly. DFT Assistant is composed of two elements: Chain Checker and Access Viewer. Chain Checker identifies errors in a JTAG scan chain, reporting them to the developer. Access Viewer overlays the boundary scan access onto the schematic diagram, allowing users to see which components are accessible using boundary scan, and where test coverage can be extended. DFT Assistant is free of charge.
