Abstract: Some example embodiments include a computer-implemented method for designing an integrated circuit. The computer-implemented method includes receiving a hierarchical network design for the integrated circuit, wherein the hierarchical design comprises a number of components that are coupled together. The computer-implemented method includes detecting that a component of the number of components has at least one of failed timing and incomplete timing based on a problem that comprises at least one of a missing assertion, one or more missing latches, a source driver having an input source slew that is greater than a source slew limit threshold, and a sink having an input sink slew that is greater than a sink slew limit threshold. The computer-implemented method includes replacing the component with a different component that is independent of the problem and testing others components of the number of components based on the different component.

Abstract: Monitoring a series of products of the kind in which the presence of foreign bodies in the product being monitored is detected by the characteristic magnetic field phase difference each material exhibits. The signal generated by a satisfactory product having no foreign body in it is used as the datum for judging whether the next subsequent product is free from a foreign body or not.
