AMS Verification

Disciplines

• AMS architecture and specification^AAO
  • Schematic & Circuit Design: maturity 0.5, Draft. Specification clarified against the schematic review and the verification results, with every change controlled.
  • AMS Verification: maturity 0.5, Draft. Specification clarified against the schematic review and the verification results, with every change controlled.
  • Custom Layout: maturity 0.8, Feature complete. Specification matches the complete layout; only clarifications remain.
• Analog circuit design^DAO
  • Schematic & Circuit Design: maturity 0.5, Draft. Schematics sized and simulated at nominal conditions and the main corners, reviewed at the schematic design review, then corrected from the corner runs until released to layout.^DAAO
  • AMS Verification: maturity 0.5, Draft. Schematics sized and simulated at nominal conditions and the main corners, reviewed at the schematic design review, then corrected from the corner runs until released to layout.
• RF and millimetre-wave design^A
  • Schematic & Circuit Design: maturity 0.5, Draft. RF schematics sized and simulated across corners, with first electromagnetic models of inductors and key interconnect.^A
  • AMS Verification: maturity 0.5, Draft. RF schematics sized and simulated across corners, with first electromagnetic models of inductors and key interconnect.
  • Custom Layout: maturity 0.8, Feature complete. RF layout complete, with electromagnetic models of the drawn passives and interconnect.^A
• Process, devices and design kit^AAO
  • Schematic & Circuit Design: maturity 0.5, Draft. Device models and design kit released for schematic design at the schematic review.
  • AMS Verification: maturity 0.8, Feature complete. Corner and statistical models proven in the verification runs; the design kit is stable.
  • Custom Layout: maturity 1.0, Complete. Design kit, rule decks and extraction decks fixed for layout and sign-off.
• AMS verification^AA
  • Schematic & Circuit Design: maturity 0.3, Sketched. Verification plan final at the schematic review; test benches and first behavioural models built.^D
  • AMS Verification: maturity 0.5, Draft. Corner and Monte Carlo results within specification or waived, behavioural models checked against the circuit and mixed-signal checks passed: pre-layout verification signed off.
• Custom layout^DA
  • Schematic & Circuit Design: maturity 0.3, Sketched. Floorplan drafted from the reviewed schematics, with matched groups and sensitive signals identified.^A
  • AMS Verification: maturity 0.5, Draft. Floorplan agreed, with matched devices, guard rings and sensitive routes placed; full layout starts from the schematics released to layout.
  • Custom Layout: maturity 0.8, Feature complete. Layout drawn and clean for design rules and layout versus schematic; matching review held.
• Extraction, reliability and ESD checks^AA
  • Schematic & Circuit Design: maturity 0.3, Sketched. ESD protection plan final at the schematic review, with the reliability rules for the circuit.
  • AMS Verification: maturity 0.5, Draft. Extraction, electromigration, IR drop and ESD checks set up and tried on the floorplan.
  • Custom Layout: maturity 0.8, Feature complete. Parasitics extracted from the complete layout; reliability and ESD checks under way.
• Integration and hand-off^DA
  • Schematic & Circuit Design: maturity 0.3, Sketched. Interface and pin definition agreed with the chip the block goes into.
  • AMS Verification: maturity 0.5, Draft. Behavioural model and pin-out shared with integrators for early chip simulation.
  • Custom Layout: maturity 0.8, Feature complete. Abstract and integration views drafted from the complete layout.
• Silicon characterisation^A
  • AMS Verification: maturity 0.0, Specified. Characterisation owner named, with the bench equipment, conditions and sample numbers scoped from the specification and the verification plan; test points not yet defined.
  • Custom Layout: maturity 0.3, Sketched. Measurement needs, test points and bench approach agreed with the circuit and layout designers.
• Mixed-signal production test^A
  • Custom Layout: maturity 0.0, Specified. Test access and trim approach reviewed with the circuit and layout designers.
• Qualification and reliability^A
  • Custom Layout: maturity 0.0, Specified. Likely qualification standard and the ESD and latch-up levels the protection being drawn must meet reviewed with layout; no mission profile or plan yet.
• AMS product management^DO
  • Schematic & Circuit Design: maturity 0.3, Sketched. Business case and product requirements approved, with requirements tracked against the design.
  • AMS Verification: maturity 0.5, Draft. Requirements confirmed against the verified circuit; lead customers engaged.
  • Custom Layout: maturity 0.5, Draft. Requirements confirmed against the verified circuit; lead customers engaged.
