We automated our ECAD-MCAD BOM synchronization process using Python scripts that integrate with Agile 9.3.6 CAD Integration module. Previously, our engineering team spent 4-6 hours weekly reconciling BOMs between electrical and mechanical designs, leading to frequent mismatches during product launches.
Our solution implements automated BOM mapping by parsing CAD metadata and aligning component attributes across ECAD-MCAD boundaries. The script runs nightly, extracting part numbers, quantities, and reference designators from both domains.
# Core sync logic
ecad_parts = extract_ecad_bom(pcb_file)
mcad_parts = fetch_agile_bom(assembly_id)
matched, conflicts = align_components(ecad_parts, mcad_parts)
sync_to_agile(matched, conflicts)
This CAD integration scripting approach reduced BOM discrepancies by 89% and cut synchronization time to under 30 minutes. The automated workflow now handles 200+ assemblies monthly, freeing engineers to focus on design validation rather than data reconciliation.
For large BOMs, batch operations are essential. Instead of individual line item updates, aggregate changes and use Agile’s bulk import functionality. We’ve seen 10x performance improvements using file-based imports versus API calls for assemblies over 300 items. Also consider implementing delta detection - only sync components that actually changed rather than the entire BOM structure.
How does your script handle revision control? One of our biggest pain points is ensuring ECAD and MCAD are synchronized to the same design revision. If the PCB is at Rev C but the enclosure is still at Rev B, the BOM sync creates chaos downstream in manufacturing.
Great question. We implemented a mapping dictionary that translates between naming conventions. The script uses fuzzy matching algorithms to identify equivalent parts even when numbering differs. For instance, resistors might be ‘R0402-10K’ in ECAD but ‘RES-0402-10KOHM’ in MCAD. Our alignment logic normalizes these to a canonical format before comparison, then flags anything below 85% confidence for manual review. This catches about 12% of parts that need human validation.
Impressive automation! How do you handle component attribute mismatches between ECAD and MCAD systems? For example, when electrical engineers use different part numbering conventions than mechanical? We’re facing similar challenges with our Mentor Graphics to Agile integration.
