📄 Intake Prerequisite (BYOF) & Free PDF Datasheet Pad-Geometry Verifier
Prerequisite: Bring Your Own Footprints (We Verify, Never Author)
Run “Update PCB from Schematic” in KiCad, Altium, or Allegro before uploading so all component footprints and netlists are embedded in your board file. We verify your existing pad geometry and synthesize placement + 100% routed copper—we do not create custom library footprints.
📄 Free Embedded Footprint & Pad-Geometry Verification (100% Free Tool)
Upload any manufacturer component datasheet (.pdf, .kicad_mod, or include PDFs inside your project .zip) to cross-check the footprints already embedded in your uploaded board file against IPC-7351B pad pitch, pad dimensions, thermal pad (EPAD), and antenna/inductor keepout rules.

🧬 Full v6.1.0 Capability Matrix • Binary OLE2 Altium, Multi-ECAD & Physics-Verified Synthesis

Complete Feature Set: From Binary Altium / Allegro / Schematic to 0-DRC Silicon

Every synthesis job automatically executes our full 8-pillar physical design, high-speed timing closure, and electrical sign-off pipeline:

1. Native Binary OLE2 Altium & Multi-ECAD
True Binary OLE2 Altium Designer In & Out (.PcbDoc ↔ .PcbDoc, preserving Components6, Polygons6, Models & blind/buried vias), Specctra (.dsn ↔ .ses), IPC-2581 XML, and KiCad 8/9/10.
2. Embedded Footprint Verification & Turnkey Placement
Upload your board with embedded footprints (Update PCB from Schematic already run)—automatically verifies IPC-7351B pad geometry and clearances, then synthesizes 2L–16L stackup, reference planes, component placement, and 3D routing.
3. PDF Datasheet Keepout Compiler
Ingests component PDF datasheets & application notes (Taoglas, Ignion, Johanson, Murata, TI, Nordic, u-blox) to enforce board-edge antenna mounting, multi-layer copper keepout windows, and galvanic isolator creepage trenches.
4. Picosecond Flight-Time (`ps`) & Skew
Unconditional picosecond flight-time closure accounting for outer microstrip vs. inner stripline effective permittivity (εeff), layer-span via barrel delay, and outward-facing differential-pair phase-bump selection.
5. 3D Layer-Span Stacked μVias & BGA
True 3D layer-span intersection checks allow non-overlapping blind/buried microvias (F.Cu→In1.Cu and In2.Cu→B.Cu) to stack vertically for 0.40 mm BGA / WLCSP fanout with full-radius escape clearance verification.
6. Topological Tightening & Snowman Teardrops
Topological trace-path tightening, redundant via elimination, and Snowman pad/via teardrops that shorten total wirelength by 14%+ and eliminate acute acid traps and drill breakout across all copper layers.
7. 3D Nodal G·V=I & 2.5D Return Audit
Solves the connected 3D copper conductance network (G·V = I) across outer/inner copper weights and vias for DC IR-drop sign-off, 50Ω RF return-via stitching, and 2.5D reference-plane split return-loop auditing.
8. Zero-VIPPO DFM & Multi-Seed Synthesis
Parallel multi-seed tournament synthesis inside our Cloud Synthesis Enclave plus automated 4-point DFM repair: Zero-VIPPO paste-aperture via relocation, switching-node polygon synthesis, thermal spoke repair, and silkscreen de-collision.
