This motivates new ATPG algorithms to improve test effectiveness specifically for HTD faults. This paper presents DEFT (Differentiable Automatic Test Pattern Generation), a new ATPG approach that reformulates the discrete ATPG problem as a continuous optimization task. DEFT introduces a mathematically grounded reparameterization that aligns the expected continuous objective with discrete fault-detection semantics, enabling reliable gradient-based pattern generati","authors_text":"Jos\\'e Moura, Shawn Blanton, Wei Li, Yang Zou, Yixin Liang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2025-12-26T16:47:59Z","title":"DEFT: Differentiable Automatic Test Pattern Generation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2512.23746","kind":"arxiv","version":3},"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:a213f29e50b0abcc718d0465a3ecd8742f24da260b9d2f980f734ef5b0c07d08","target":"record","created_at":"2026-05-20T01:05:05Z","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":"00438f6867e5c99574e5329c56a24b35db608fb05fa4bfb9b12354ef88911895","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2025-12-26T16:47:59Z","title_canon_sha256":"cb5a6c97a5c758951819202ed5b9def3dbb7ccfd18da2b20461c862a2c9fd12b"},"schema_version":"1.0","source":{"id":"2512.23746","kind":"arxiv","version":3}},"canonical_sha256":"cd44454655e14627ad4281d031cbff10f909205e84f00cb536af85e564912130","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cd44454655e14627ad4281d031cbff10f909205e84f00cb536af85e564912130","first_computed_at":"2026-05-20T01:05:05.359325Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T01:05:05.359325Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MBsvMpt5sp18f+SN9fjwtePqThNjx70659Fr4+pGnLtqvn4oqPEYexLSuS2sIQrljR2YnSMI+QlSQ6Dm1mbACQ==","signature_status":"signed_v1","signed_at":"2026-05-20T01:05:05.360081Z","signed_message":"canonical_sha256_bytes"},"source_id":"2512.23746","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a213f29e50b0abcc718d0465a3ecd8742f24da260b9d2f980f734ef5b0c07d08","sha256:ab1d840e00c2f26fdd54e0845017062e4cd8f77567925afdeb4b9d8c9068f35c"],"state_sha256":"7250c973af9fa991d15117be99b75e50c0e5f09e774fe0d2951a0b69414fe367"}
