verification strat-egies. With a single command, Conformal Smart LEC analyzes the characteristics of both the golden and revised designs, such as datapath type and logic complexity. Based on the results of the analysis, the command automatically executes the most appropriate strategy to complete the comparison (Figure 2).

Conformal Smart Logic Equivalence Checker is the next-generation equivalency checking solution. With massively parallel architecture and adaptive proof technology, the Conformal Smart LEC delivers dramatic turnaround time improvements in equivalence checking by over 20X for RTL-to-gate comparisons.

Conformal Smart LEC has an extensive portfolio of formal solvers that can handle all conceivable design synthesis and imple-mentations. Adaptive proof technology orches - trates the solvers so users do not have to iterate over their verification strat-egies.
