Choose the top cell you intend to hand off. Die dimensions follow this selection; layer, element and cell counts describe the whole library.

Cell hierarchy
Reviewable RFQ summary
Includes the selected top-cell name, file checksum and estimated bounds. Review these identifiers before sharing. No geometry is uploaded; the RFQ link carries only the area estimate.
Continue the handoff check
Download the inspection record, then select the same layout and import that record in Report Revision Check. The report check verifies its hash and selected top before comparing your report metadata. Finish with the handoff manifest.
How it works (and what stays private)
Nothing is uploaded
Your file is read withFileReader into memory and parsed by an inline Web Worker on your own device. There is no backend and no network request with your data. The "RFQ" buttons only build a link/text from the metadata (die size + counts) you see on screen.
What it reads
It walks the GDSII record stream (big-endian), decodes theUNITS record's metres-per-database-unit to get true micrometres, collects every cell (STRNAME), every reference (SREF/AREF) to build the hierarchy, and every (LAYER, DATATYPE) pair. The die size is the bounding box of the top cell, computed recursively through all instances — each instance transformed by its reflection → magnification → rotation → translation, with arrays (AREF) handled in closed form. Reference cycles and missing cells are detected and skipped, never hung on.
Approximations
The die box is an axis-aligned bounding box (slightly conservative for rotated layouts);PATH width end-caps are approximated to ±½ width; TEXT labels are excluded from die size (they can sit outside the layout). Random things a real quote depends on — process, mask grade, packaging — aren't in a GDS and aren't inferred here.
