JTAG Technologies has updated its ProVision boundary-scan development tools suite to include the continuity test module Buzz. The software uses a project database structure that analyzes the boundary-scan and nonboundary-scan elements of a design to create a full set of tests and in-system programming applications. The Buzz module allows a user, with minimal design information, to check the continuity between two or more pins quickly. Using an intuitive user interface, the user can drag and drop pins into a continuity test panel within the interface and Buzz-out a connection as is traditionally done with a DMM. A Watch feature monitors asynchronously the activity of a selected pin without disturbing the operation of the unit under test.
