Abstract

See full text

Various methods for analyzing mutual inductance in an integrated circuit layout are disclosed. In one exemplary embodiment, for example, circuit design information indicative of a first inductor and a second inductor is received. A dipole moment associated with the first inductor is determined, where the magnetic field associated with the dipole moment is representative of magnetic fields created by respective turns in the first inductor. A mutual inductance between the first inductor and the second inductor is determined by determining a magnetic flux of the magnetic field of the dipole moment through surfaces bounded by respective wire segments of the second inductor.
