Automotive Compliance (ASPICE v4.0)
Capability Level 1: 99.4% Missing Traceability automatically detected & fixed
Reference case: 13,431 Design Items (SWE.3), only 84 (0.6%!) linked to tests. The gap was invisible — until the graph found it.
Bug #1: Wrong Classification (SWE.3 → classified as SWE.2)
The classification engine read the aspice_process property only at document level, not per item. An SWE.3 item in an SWE.2 document was misclassified.
BEFORE (wrong):
Document: "SWE.2_Design_Specs" → Node classified as SWE.2 ❌
AFTER (fixed):
Item-level aspice_process read FIRST → Node correctly SWE.3 ✓
Impact: +8-10% SWE.3 coverage
Bug #2: Wrong verified_by Links (Test → SWE.2 instead of SWE.3)
The linker algorithm connected tests to all architecture items — without SWE.3 filtering. Result: 3,608 wrong SWE.2 links, 584 wrong SWE.1 links.
Impact: +5-8% precision, duplicates eliminated
Bug #3: CRITICAL — Name-Matching Gap: 38% Missing Links
80% of SWE.3 items had zero connection to code. Reason: Code was never captured as arch_relation. Solution: Semantic name-matching.
Three Link Layers BEFORE:
Layer 1: Manual SWE.4 → 84 items (0.6%)
Layer 2: Code implements → 621 items (4.6%)
Layer 3: NOT PRESENT → 0 items
─────────────────────────────
Total: 0.6% ❌ FAIL AFTER with Name-Matching:
SWE.3 Title: "CDD_I2c_WriteByte_Run"
↓ exact case-insensitive match
C++ Function: "cdd_i2c_writebyte_run" → 5,187 matches
