Assertion Based Verification Techniques
Assertion Based Verification (ABV) defines design properties using formal constructs such as SystemVerilog Assertions (SVA) and Property Specification Language (PSL). These properties are monitored across simulation, formal analysis, and hardware acceleration environments. In simulation, assertions serve as real-time monitors for protocol violations. In formal tools, they act as the core of property-checking engines. In emulation, they assist in rapid failure identification. ABV enables reuse of properties across environments and supports integration with coverage analysis, enhancing debug precision and verification completeness. Proper assertion planning and structuring are critical for ensuring consistency, automation, and coverage-driven closure.

resourceDescription
Assertion Based Verification introduces a methodology that encodes expected behaviors directly into the design verification flow using formal assertion languages. SystemVerilog Assertions (SVA) and Property Specification Language (PSL) are used to describe protocol requirements, data validity, timing relationships, and control sequences. These assertions form a specification layer that is automatically checked during all stages of the verification process. By treating assertions as primary verification artifacts, the environment can detect design violations at the point of failure, significantly reducing debugging effort and increasing diagnostic accuracy. Assertions function differently depending on the verification engine. In simulation environments, they operate as real-time checkers embedded within the design hierarchy. They monitor conditions at each simulation step and trigger failures when properties are violated. In formal verification, the same assertions are treated as properties to be proven exhaustively, providing exhaustive validation of critical design intent without requiring explicit stimulus. In emulation and acceleration platforms, assertions are compiled into ...
