Title
LEAP: An Accurate Defect-Free IDDQ Estimator
Abstract
The quiescent current (IDDQ) consumed by a CMOS IC is a good indicator of the presence of a large class of defects. However, the effectiveness of IDDQ testing requires appropriate discriminability of defective and defect-free currents, and hence it becomes necessary to estimate the currents involved in order to design the IDDQ test. In this work, we present a method to estimate accurately the non-defective IDDQ consumption based on a hierarchical approach at electrical (cell) and logic (circuit) levels. This accurate estimator is used in conjunction with an ATPG (Automatic Test Pattern Generation) to obtain vectors having low/high defect-free IDDQ currents.
