Abstract
A method and system are provided for computing behavioral level observabilities of a digital system. In one example, a logic network is provided for performing an observability analysis at the behavioral level of a digital system. The logic network includes logic objects configured to emulate behavioral observabilities computed from a control data flow graph (CDFG), wherein the logic objects include at least one of: first logic objects configured to compute a token observable condition (TOC) of an edge of the CDFG; and second logic objects configured to compute a node observable condition (NOC) of a node of the CDFG. A logic optimization is used to optimize the logic network to obtain an optimized logic network of the behavioral observabilities.
