This volumecontains the proceedingsof the Second InternationalConferenceon Formal Methods in Computer-Aided Design (FMCAD'98), organized November 4-6, in Palo Alto, California, USA. The rst event of this series was organized byMandayamSrivasand Albert Camilleriin 1996 inPaloAlto. FMCAD,which evolved from the series Theorem Provers in Circuit Design (TPCD), strives to beapremierforumfordisseminatingresearchinFormalVeri cation(FV) me- ods for digital circuits and systems, including processors, custom VLSI circuits, microcode,andreactivesoftware.Inadditiontosigni cantcase-studiesandve- cationapproaches,FMCADalsoendeavorstorepresentadvancesinthedriving technologies for veri cation, including binary decision diagrams, model che- ing,symbolicreasoning(theorem proving),symbolicsimulation,andabstraction methods.
