Latest Patents

Ganesan holds a patent titled "Method and system for automatically determining transparency behavior of non-scan cells for combinational automatic test pattern generation." This innovative method encompasses generating test vectors specifically for scan-based sequential circuits that incorporate non-scan cells. The invention consists of a computer-implemented step that initiates with receiving a netlist description of an integrated circuit comprising both scan cells and non-scannable cells.

The core of this invention identifies scenarios in which certain non-scan cells may demonstrate sequential transparency behavior. By characterizing these cells as either sequentially transparent or non-transparent, Ganesan's method allows for the transformation of non-scan cells that exhibit sequential transparency behavior into transparent logic models during the combinational ATPG analysis. This approach notably enhances the fault coverage of the test patterns produced, contributing to more reliable circuit testing.
