Execution Responsibility

We own backend execution and tapeout readiness as a single accountable team.

01 Implementation

Netlist handoff → signoff-ready GDSII

  • Floor planning & power grid
  • Place & Route execution
  • Clock Tree Synthesis
  • Multi-corner timing closure

02 Signoff

Verification → foundry submission readiness

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

03 Tapeout Coordination

GDS freeze → mask acceptance

  • PDK compliance validation
  • Foundry submission package
  • MPW shuttle coordination
  • GDS acceptance confirmation

Typical backend cycle

Representative Tapeout Work

  • TSMC 28nm1.8M-instance mixed-signal SoC, 6 clock domains, 800MHz timing-critical SerDes interface, 45 signoff corners
  • SMIC 55nmSensor AFE with embedded 12-bit ADC, OCV derating rebuild across analog/digital PVT corners, first-pass silicon
  • UMC 110nmAnalog-dominant power management controller, full-custom analog block integration with digital wrapper
  • SMIC 40nmIoT connectivity SoC, 3 independent voltage domains, UPF-based implementation with voltage-aware signoff

Where Teams Typically Break

  • Fragmented backend ownership
  • Timing closure pushed to late stage
  • Tapeout handled by third parties without context
  • ECO without physical awareness

We execute and own the full flow — from implementation through tapeout acceptance.

Case Study

SMIC 55nm — Sensor AFE with Embedded ADC

Delivered under tight schedule with first-pass silicon success

Node|55nm SMICDesign type|Sensor AFE / embedded ADCCycle|9 weeks to tape-outResult|First-pass silicon success

Situation

Mixed-signal AFE with embedded 12-bit ADC. Customer had exited a previous backend engagement after persistent timing failures across temperature corners and a failed first silicon attempt. Deadline to SMIC shuttle window: 9 weeks.

What we did

Identified timing violations rooted in insufficient OCV derating for mixed-signal paths. Rebuilt constraint set with separate PVT corners for analog and digital domains. Full incremental re-signoff after each ECO cycle. ICC package assembled and submitted ahead of shuttle window with a one-week buffer.

Outcome

First-pass silicon success. All analog performance targets met on silicon. Customer re-engaged for 28nm follow-on project.
