LDRA Tool Suite vs SeaHorn

LDRA Tool Suite combines verification, testing, and requirements traceability for safety-, security-, and mission-critical software development. Its core capabilities include static and dynamic analysis, coding standards checks, unit, integration, and system testing, plus compliance reporting. The main components are TBvision, TBrun, TBmanager, and LDRA Testbed. TBmanager links requirements and design artifacts with source code, test cases, and verification results to maintain audit trails. Structural coverage analysis includes statement, branch, and MC/DC metrics at unit, integration, and system levels. LDRA lists support for standards including DO-178C, ISO 26262, IEC 61508, IEC 62304, and EN 50716, as well as integrations with Atlassian Jira, IBM Engineering Requirements Management DOORS, Jenkins, Bamboo, and GitLab. Listed languages include C, C++, Java, Ada95, and Assemblers. The suite is self-hosted on listed Windows, Linux, and Mac hosts. Pricing is on request. LDRA offers a 30-day free trial through a registration page that requests company and contact information.

SeaHorn is a free, open-source framework for automated analysis of C and other LLVM-based programs, developed mainly for research in automated verification. It is not an out-of-the-box static analyzer. Its frontend prepares LLVM IR bitcode, and its middle end converts optimized bitcode into verification conditions written as Constrained Horn Clauses. Backend engines use SMT-based model checking, including PDR/IC3 techniques, and CRAB can provide numerical invariants through abstract interpretation. SeaHorn supports abstract interpretation, context-sensitive pointer analysis, bounded model checking, constrained-Horn-clause software model checking, and termination or non-termination analysis. For C programs with assertions, `sea pf` translates the program, generates and solves verification conditions, displays invariants for safe results, or saves a counterexample for violations. `sea inspect` reports program structure and can produce memory or call-graph data. The framework also checks generated clauses for inconsistent code fragments using path coverage. Docker is described as the easiest starting point, with a nightly image refreshed daily. Building requires LLVM, Z3, and Boost, whose exact versions change. SeaHorn runs on Linux, macOS, or self-hosted systems under a modified BSD license.
