Abstract: The task of system design is shared by all engineering disciplines, each coming
with its own techniques. In spite of their differences in tools, there is large
intersection in their conceptual approach to design. In this talk, we exploit
this commonality to take an abstract view of systems and their composition. We
understand systems and subsystems in terms of their assume-guarantee
specifications, or contracts.
Assume-guarantee contracts are formal specifications that state (i) the
assumptions that a design element makes on its environment and (ii) the
guarantees it delivers when the environment behaves according to the contract's
assumptions. Contracts come with a rich algebra that allows us to carry out
several design-relevant tasks: obtaining system-level specifications from
component specifications, finding specifications of components that need to be
added to a design in order to meet an objective, etc. We will introduce the
algebra of contracts and discuss how the various algebraic operations relate to
system-design tasks. We will discuss hypercontracts, an extension of
assume-guarantee reasoning to support the formal analysis of key security and
robustness properties. We will also discuss the application of this methodology
and Pacti, a software package that supports system design using contracts, in
applications ranging from space-mission design to synthetic biology.
Bio: Inigo Incer is a postdoctoral researcher at Caltech and UC Berkeley. He obtained
his PhD from UC Berkeley in 2022 under the guidance of Alberto
Sangiovanni-Vincentelli. He is interested in all aspects of cyber-physical
systems, emphasizing formal methods and AI that support their compositional
design and analysis. Before pursuing a PhD, Inigo was an IC designer in Austin.
His work has been supported by the NSF/ASEE eFellows program and the UC Berkeley
