Reachability analysis consists in computing the set of states that are reachable by a
dynamical system from all initial states and for all admissible inputs and parameters. It is a …

This paper aims to explore diverse landscape of Phase Locked Loops (PLLs), offering a
comprehensive categorization and in-depth analysis of their underlying working principles …

Despite the wide applications of neural networks, there have been increasing concerns
about their vulnerability issue. While numerous attack and defense techniques have been …

Cyber-physical systems (CPS) are heterogeneous, because they tightly couple computation,
communication, and control along with physical dynamics, which are traditionally …

This paper presents hybrid automaton modeling, comparative model validation, and formal
verification of stability through reachability analysis of pulse width modulation (PWM) dc-dc …

One often wishes for the ability to formally analyze large-scale systems-typically, however,
one can either formally analyze a rather small system or informally analyze a large-scale …

In today's age of digital technology, ethical concerns regarding computing systems are
increasing. While the focus of such concerns currently is on requirements for software, this …

We present ABCD-NL, a technique that approximates non-linear analog circuits using purely
Boolean models, to high accuracy. Given an analog/mixed-signal (AMS) system (eg, a …

We address the problem of formally verifying nonlinear analog circuits with an uncertain
initial set by computing their reachable set. A reachable set contains the union of all possible …

We present the results of the ARCH 1 2022 friendly competition for formal verification of
continuous and hybrid systems with linear continuous dynamics. In its sixth edition, two tools …
