They are usually expressed in the form of natural language sentences and checked for errors manually, e.g., by peer reviews. Manual checks are error-prone, time-consuming and not scalable. With the increasing complexity of cyber-physical systems and the need of operating in safety- and security-critical environments, it became essential to automatize the consistency check of requirements and build artifacts to help system engineers in the design process.","authors_text":"Simone Vuotto","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2018-04-27T13:17:57Z","title":"Consistency Checking of Functional Requirements"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.10486","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:77e42a312c9b0d39f109a9322b3f9f4f58956c482254a29d9c9e34936e26a8c8","target":"record","created_at":"2026-05-18T00:17:20Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"157f8a9a8044fc2e594f01ed0a2817a01909e7109ebd55c69aa0c1a1ce8511fe","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2018-04-27T13:17:57Z","title_canon_sha256":"da0e71334950713984f2df70e7977dfebda20347fec7d1ff38e6045e40617f72"},"schema_version":"1.0","source":{"id":"1804.10486","kind":"arxiv","version":1}},"canonical_sha256":"fb43259687d4b14a041de623f633e3f35c3ca29ee95fb4eb7c188cd7845a3b2a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fb43259687d4b14a041de623f633e3f35c3ca29ee95fb4eb7c188cd7845a3b2a","first_computed_at":"2026-05-18T00:17:20.642398Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:17:20.642398Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ld4IlGvLb21aOddvm7ODK8Lj/86dHR6YiMXbwTEEv9d4YQYZArUdLpRfE2gVGY/FJqlUckfGu7E1kGPBayTpAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:17:20.642932Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.10486","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:77e42a312c9b0d39f109a9322b3f9f4f58956c482254a29d9c9e34936e26a8c8","sha256:2d434db528f42a2edf79cb6611324b5bf0b0ad4be27d739933873bf542e33a46"],"state_sha256":"59a991765c0a66a33bd90680daea3e2adae3e802458eb60601b9b6d7e230d0e8"}
