Reviewable RFQ summary
This file and its inspection are stored by MST. The MPW enquiry link below carries only the area estimate; you may add project details here to associate them with the original file.
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 the inspection and storage work
The GDS parser runs in your browser. The original attachment and a summary of its results are also submitted to MST and stored for staff review and follow-up. File uploads use an encrypted connection; originals are available only through authorized staff access. The inspection does not run DRC/LVS or approve a tapeout.
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.
