Abstract
An aspect of the invention relates to a method, apparatus, and computer-readable medium for processing schematic data for an integrated circuit having a boundary scan architecture. A path through cells of the schematic data to generate a hierarchy of cells associated with a boundary scan chain. Each ignore cell in the hierarchy is pruned. Each short cell in the hierarchy is replaced with a direct connection. A shadow net is added to each net of the hierarchy. Each of the cells in the hierarchy is flattened in a bottom-up fashion.
