First trench-type silicon carbide MOSFET cuts on-resistance

Rohm Semiconductor has recently announced the development and mass production of a silicon carbide (SiC) MOSFET that it claims as the first suc transistor to use a trench structure. Compared to existing planar-type SiC MOSFETs, ON resistance is reduced by 50% in the same chip size, making it possible to significantly decrease power loss.

Formal verification company provides technology access on “app” model

Formal verification has long held promise as a verification tool for the SoC design chain – but the arcane nature of the applied mathematics involved has limited its use to a subset of specific areas.
German specialist OneSpin Solutions has now found a way that third parties can build tools on the base of its formal verification “engines”, applying the full power of the technology while retaining full secure over its underlying formal intellectual property.
