Tapeout Execution Process
From netlist handoff to foundry-accepted GDSII — one accountable execution flow.
We do not stop at backend implementation. We own tapeout readiness, submission, and 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
Netlist Handoff
- Design review and constraint sanity check
- Clock definition and domain partitioning
- PDK alignment and flow setup
Backend Implementation
- Floorplan and power grid definition
- Placement and routing
- Clock Tree Synthesis (CTS)
- Early timing closure across PVT corners
Signoff & Validation
- Multi-corner STA closure
- DRC / LVS verification
- IR drop and EM validation
- Physical verification signoff
Tapeout Preparation
- GDS freeze and final consistency checks
- Mask data preparation
- Documentation and submission package assembly
Foundry Submission
- PDK compliance validation
- Submission checklist alignment
- MPW or full mask submission coordination
GDS Acceptance
- Foundry feedback handling
- Issue resolution (if any)
- Final acceptance confirmation
Where Projects Fail
- —Timing closure deferred to late stage
- —Incomplete signoff coverage
- —Lack of coordination with foundry requirements
- —ECO changes without physical awareness
We eliminate these risks by executing the full flow as one accountable team.
What We Deliver
- Signoff-ready GDSII
- Verified timing closure across corners
- DRC/LVS clean database
- Foundry submission package
- Tapeout acceptance confirmation
