Lazy Self-composition for Security Verification
The secure information flow problem, which checks whether low-security outputs of a program are influenced by high-security inputs, has many applications in verifying security properties in programs. In this p...

Trace-based Analysis of Memory Corruption Malware Attacks
Understanding malware behavior is critical for cybersecurity. This is still largely done through expert manual analysis of the malware code/binary. In this work, we introduce a fully automated method for malwa...

IC3 - Flip** the E in ICE
Induction is a key element of state-of-the-art verification techniques. Automatically synthesizing and verifying inductive invariants is at the heart of Model Checking of safety properties. In this paper, we stud...

Model checking unbounded concurrent lists
We present a model checking-based method for verifying list-based concurrent set data structures. Concurrent data structures are notorious for being hard to get right and thus, their verification has received ...

Reduction of Resolution Refutations and Interpolants via Subsumption
Propositional resolution proofs and interpolants derived from them are widely used in automated verification and circuit synthesis. There is a broad consensus that “small is beautiful”—small proofs and interpo...

Using Flow Specifications of Parameterized Cache Coherence Protocols for Verifying Deadlock Freedom
We consider the problem of verifying deadlock freedom for symmetric cache coherence protocols. While there are multiple definitions of deadlock in the literature, we focus on a specific form of deadlock which ...

SAT Based Verification of Network Data Planes
Formal verification has seen relatively less application in verifying computer networking infrastructure. This is in part due to the lack of clean layers of abstraction that enable design modeling and specific...

Coverage-Based Trace Signal Selection for Fault Localisation in Post-silicon Validation
Post-silicon validation is the time-consuming process of detecting and diagnosing defects in prototype silicon. It targets electrical and functional defects that escaped detection during pre-silicon verificati...

Modeling Firmware as Service Functions and Its Application to Test Generation
The term firmware refers to software that is tied to a specific hardware platform, e.g., low-level drivers that physically interface with the peripherals. More recently, this has grown to include software that...

passert: A Tool for Debugging Parallel Programs
passert is a new debugging tool for parallel programs which allows programmers to express correctness criteria using a simple, expressive assertion language. We demonstrate how these parallel assertions allow the...

Wolverine: Battling Bugs with Interpolants
Wolverine is a software verifier that checks safety properties of sequential ANSI-C and C++ programs, deploying Craig interpolation to derive program invariants. We describe the underlying approa...

Verification of Computer Switching Networks: An Overview
Formal verification has seen much success in several domains of hardware and software design. For example, in hardware verification there has been much work in the verification of microprocessors (e.g. [1]) an...

Runtime Verification: A Computer Architecture Perspective
A major challenge in hardware verification is managing the state explosion problem in pre-silicon verification. This is seen in the high cost and low coverage of simulation, and capacity limitations of formal ...

Parallel Assertions for Architectures with Weak Memory Models
Assertions are a powerful and widely used debugging tool in sequential programs, but are ineffective at detecting concurrency bugs. We recently introduced parallel assertions which solve this problem by provid...

Predicting Serializability Violations: SMT-Based Search vs. DPOR-Based Search
In our recent work, we addressed the problem of detecting serializability violations in a concurrent program using predictive analysis, where we used a graph-based method to derive a predictive model from a gi...

Parameterized Model Checking of Fine Grained Concurrency
Concurrent data structures are provided in libraries such as Intel Thread Building Blocks and Java.util.concurrent to enable efficient implementation of multi-threaded programs. Their efficiency is achieved by...

Hardware Verification: Techniques, Methodology and Solutions
Hardware verification has been one of the biggest drivers of formal verification research, and has seen the greatest practical impact of its results. The use of formal techniques has not been uniformly success...

A Case for Runtime Validation of Hardware
Increasing hardware design complexity has resulted in significant challenges for hardware design verification. The growing “verification gap” between the complexity of what we can verify and what we can fabric...
