SysNav™ is a layout visualizing and signal tracing CAD navigation software solution for printed circuit board (PCB), multi-chip module, and stacked die applications. It extends Synopsys Avalon's die-level failure analysis capabilities to the packaging industry. SysNav is the only commercially available tool able to integrate multiple, interactive IC and PCB designs with seamless CAD navigation capabilities. SysNav allows rapid signal traces on dies, stacked dies, multi-chip modules, and PCBs. Both Fab and Fabless teams can now trace a signal from chip to board, back to chip and then quickly navigate failure analysis tools to X, Y locations to determine the root cause of the fault.
