Finding all DC operating points using interval-arithmetic-based verification algorithms
Finding operating points of circuits is a crucial first step for simulation and verification.
Traditional operating point analyses such as homotopy analysis do find an
operating point. However, a circuit may have many DC equilibria, and failing to
consider an unintended initial condition can lead to failures escaping to the physical
silicon. This work presents a method for finding all DC equilibrium points;
this approach is based on interval-arithmetic-based verification algorithms; and our
open-source implementation supports state-of-the-art short-channel device models.
This work also presents what we believe to be the first, completely automatic verification
of the Rambus ring-oscillator start-up problem. Our method offers large
performance and scalability advantages when compared with the dReal and Z3
