assertions

Concept

Assertions are verification statements used to check expected properties, support coverage-oriented validation, detect errors at runtime, and localize failures. In hardware verification, they can be embedded in RTL, interfaces, or verification components and are supported by SystemVerilog Assertion. In formal software verification, helper assertions can guide tools such as Dafny, though inferring them automatically remains an active research topic.

Overview

Assertions are statements used in verification to express properties that should hold during execution, simulation, or proof. Public evidence describes assertions as widely used for functional validation and coverage analysis in both software and hardware designs, where they support runtime error detection and faster error localization. They can also be specialized for security monitoring, such as System-on-Chip vulnerability checks.

[2] Security-focused assertions can monitor System-on-Chip vulnerabilities; in the cited experiments, generated security assertions detected all inserted vulnerabilities while functional assertions generated by existing techniques missed most of them. System-on-Chip Security Assertions

[3] In a RISC-V CPU verification plan, checking mechanisms for functional correctness should be documented, and checks can be implemented as scoreboards, interface assertions, or embedded assertions inside RTL or verification components.
