SIGDA newsletter, vol 17, number June 30 Functional Verification of MOS Circuits This paper described a program which verified synchronous digital MOS circuits. Using the schematic of a MOS VLSI circuit, declarations of the logical relationships between the input signals and a specification of the intended digital behavior of a circuit Silica Pithecus verifies the circuit and returns the specific reason of why the ckcuit failed if it did. A realistic electrical model is employed. Verification is performed hierarchically, interactively and incrementally. DAGON: Technology Binding and Local Optimization by DAG Matching Technology binding is the process of mapping a technology independent description of a circuit into a particular technology. A formalism of this problem was presented as well as a solution in terms of matching patterns. DAGON takes a canonical technology independent description of a combinational circuit and a list of patterns describing both the cells in the technology and local transformations. It creates a technology bound circuit by partitioning the circuit into a forest of trees, then using a tree matching automaton to match the individual trees. A Hierarchical Approach to Test Vector Generation This paper described a hierarchical approach to test vector generation based on the
