A methodology for the insertion of a hierarchical and boundary-scan compatible self test
O.F. Haberl, Thomas Kröpf · 2003
A methodology is presented, which automatically embeds a self test architecture into hierarchically designed circuits. For each module of the design hierarchy the automatic method for the insertion of self test registers as well as the synthesis of a test control unit is presented. These self testable modules are then combined for arbitrary hierarchy levels using test management units. The concept is embedded within the boundary-scan architecture and the implementation has been integrated into a commercial design framework.>
