Tapeout Execution Process

從 netlist handoff 到 foundry-accepted GDSII — 單一 accountable execution flow。

我們不僅執行 backend implementation，更負責 tapeout readiness、submission 及 acceptance。

01

Netlist Handoff

Scope review、constraint validation、flow setup

02

Backend Implementation

Floorplan、P&R、CTS、early timing closure

03

Signoff & Validation

Multi-corner STA、DRC/LVS、IR/EM verification

04

Tapeout Preparation

GDS freeze、mask data、submission package

05

Foundry Submission

PDK compliance、checklist、MPW coordination

06

GDS Acceptance

Foundry feedback、issue resolution、confirmation

01

Netlist Handoff

  • Design review 與 constraint sanity check
  • Clock definition 與 domain partitioning
  • PDK alignment 與 flow setup
02

Backend Implementation

  • Floorplan 與 power grid definition
  • Placement and routing
  • Clock Tree Synthesis (CTS)
  • 跨 PVT corner 的 early timing closure
03

Signoff & Validation

  • Multi-corner STA closure
  • DRC / LVS verification
  • IR drop 與 EM validation
  • Physical verification signoff
04

Tapeout Preparation

  • GDS freeze 與 final consistency checks
  • Mask data preparation
  • Documentation 與 submission package assembly
05

Foundry Submission

  • PDK compliance validation
  • Submission checklist alignment
  • MPW 或 full mask submission coordination
06

GDS Acceptance

  • Foundry feedback handling
  • Issue resolution（如有）
  • Final acceptance confirmation

Projects 常見失敗點

  • —Timing closure 延遲到後期才處理
  • —Signoff coverage 不完整
  • —缺乏與 foundry requirements 的 coordination
  • —ECO 缺乏 physical awareness

我們透過以單一 accountable team 執行完整 flow 來消除這些風險。

我們的交付物

  • Signoff-ready GDSII
  • 跨 corner 的 verified timing closure
  • DRC/LVS clean database
  • Foundry submission package
  • Tapeout acceptance confirmation
