Résumé: High speed digital designs increasingly rely on circuits whose analog behavior
is critical to their correct operation and performance. Typically, circuit
simulators such as SPICE are used to verify that a circuit in an analog model
correctly implements a digital behavior. Such simulation based approaches are
tedious and cannot account for all possible inputs, loads, or model parameters.

In this talk, I will show how dynamical systems theory can be used to establish
the digital behavior of analog circuits. In this framework discrete behaviors
correspond to topological properties of the continuous, and I will present an
practical algorithm for verifying these topological properties. This approach
allows traditional SPICE models to be used for transistor behavior, and the
circuit can be verified for a large range of inputs or model parameters. I will
illustrate the approach using Seitz's arbiter circuit and the high speed, Yuan-
Svenson toggle element as examples.
