Reviewable RFQ summary
MST がこのファイルと検査結果を保存します。以下の MPW 問い合わせリンクには面積の推定値のみ含まれます。このページで要件を入力すると、元ファイルに関連付けられます。
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.
検査とファイル保存の仕組み
GDS 解析はブラウザで実行されます。元の添付ファイルと結果の概要も MST に送信され、スタッフの確認と対応のために保存されます。接続は暗号化され、元ファイルには権限のあるスタッフのみアクセスできます。この検査は DRC/LVS の実行やテープアウトの承認ではありません。
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.
