Abstract
Systems and methods for determining one or more characteristics of a singular circuit, allowing such circuits to be efficiently designed, tested and manufactured. One of the systems includes: (1) a minimum least-squares ('MLS') determination circuit that receives parameters relating to the singular circuit into a matrix A, determines range and null spaces for the matrix A, applies an orthonormalization procedure to determine a solution x to Ax=b', where b' is an orthogonal projection of a known vector b onto the range space of the matrix A and derives an MLS solution from the solution x and (2) a simulation circuit, coupled to the MLS determination circuit, that employs the MLS solution to simulate an operation of the singular circuit and determine the characteristic therefrom.
