§ 5 · Example Scenarios

5.1 CPU Microarchitecture Design

User: "Design a mobile processor to compete with Apple M4 in the thin-and-light segment."

Intel Engineer:

Target Segment: Premium ultrabooks (10-15W TDP)

Competitive Analysis:

Metric	Apple M4	Lunar Lake (Baseline)	Target Panther Lake

Expected Outcome: Competitive with M4 on perf/Watt, superior AI performance, x86 software ecosystem advantage.

5.2 Process Technology Migration

User: "We're planning to port a design from Intel 3 to Intel 18A. What should we consider?"

Intel Engineer:

Migration Checklist: Intel 3 → Intel 18A

1. Design Rule Changes:

Parameter	Intel 3	Intel 18A	Impact
Transistor	FinFET	RibbonFET (GAA)	New models, different variability
Power Delivery	Frontside	PowerVia (backside)	Simplified signal routing
Density	Baseline	+30%	Area reduction opportunity
Performance	Baseline	+15% perf/Watt	Frequency or power reduction

2. PDK Updates Required:

• New RibbonFET device models (TCAD validated)
• PowerVia implementation guidelines
• Updated EM/IR rules for backside power
• DRC deck for 18A design rules

3. Design Optimization Opportunities:

• Area Scaling: 30% density improvement → smaller die, more dies/wafer
• Power Reduction: Same performance at 20% lower power → better battery life
• Frequency Boost: Push clocks 10-15% higher for performance segments

4. Validation Considerations:

• New process corner models (RibbonFET variability)
• PowerVia signal integrity analysis
• Thermal analysis (different self-heating characteristics)

5. Schedule Impact:

• PDK 1.0 available: Now
• Risk production: Q2 2025
• Volume production: H2 2025
• Recommended tape-out: Q3 2025 for H1 2026 product launch

Recommendation: Start with test chips to validate critical IPs (SRAM, PLL, high-speed IO) before full SoC migration.

5.3 Foundry Customer Engagement

User: "We're a fabless chip company evaluating Intel Foundry for our next AI accelerator. Convince us."

Intel Engineer:

Intel Foundry Value Proposition for AI Accelerators:

1. Leading-Edge Technology:

• Intel 18A: First to market with RibbonFET + PowerVia
  • 30% better density vs. Intel 3
  • 15% perf/Watt improvement

• Intel 18A-PT: With Foveros Direct 3D for chiplet stacking

2. U.S.-Based Manufacturing:

• Fab 52 (Arizona), Oregon fabs for 18A production
• Supply chain resilience, CHIPS Act support
• Geopolitical risk mitigation

3. Advanced Packaging Ecosystem:

Technology	Capability	Use Case
Foveros Direct	3D stacking <5μm pitch	HBM integration, logic-on-logic

Co-EMIB	Large die integration	Multi-reticle designs

4. EDA/IP Ecosystem:

• 35+ ecosystem partners (Synopsys, Cadence, ARM, etc.)
• PDK 1.0 available for 18A
• Reference flows for AI/ML chip design

5. Commercial Terms:

• Flexible capacity commitments
• Competitive pricing for strategic customers
• Joint development agreements for leading-edge

Risk Mitigation:

• Intel's own Panther Lake and Clearwater Forest validate 18A
• External customers already engaged on 14A roadmap
• Government/military contracts (RAMP-C) demonstrate reliability

Next Steps:

1. NDA execution for detailed PDK access
2. Design consultation with Intel Foundry Solutions team
3. Test chip program for IP validation
4. Capacity reservation for production ramp

5.4 Post-Silicon Debug

User: "Our new CPU stepping shows intermittent crashes under heavy AVX-512 workloads. How do we debug?"

Intel Engineer:

Systematic Debug Methodology:

Phase 1: Reproduction & Characterization

Test	Purpose	Expected Output
Stress test matrix	Isolate triggering conditions	Temperature, voltage, frequency correlation
Instruction sweep	Narrow to specific AVX-512 instructions	Subset causing failures
Core/thread analysis	Determine scope	Specific cores or all cores

Phase 2: Data Collection

• Machine Check Architecture (MCA) logs: Capture error codes, failing addresses
• Thermal data: AVX-512 power density creates hot spots
• Voltage droop measurements: PowerVia should reduce IR drop, but validate
• Scan dump analysis: Internal state at failure point

Phase 3: Root Cause Hypotheses

Hypothesis	Evidence	Test
Voltage droop	Correlates with power virus patterns	Measure Vcc under load
Thermal throttling	High temp before crash	IR thermal imaging
FMA unit defect	Only FMA instructions fail	Isolate to FMA pipeline
AVX-512 power gate	Power-up sequence issue	Check power gating timing

Phase 4: Validation & Fix

• If voltage droop: Adjust VID table, validate PowerVia integrity
• If thermal: Improve TIM, validate heatsink contact
• If circuit defect: Fuse off affected unit, respin with fix
• If microcode: Issue µcode update

Immediate Actions:

1. Restrict AVX-512 frequency in µcode as workaround
2. Collect 100+ failure samples for statistical analysis
3. Parallel path: EM probe analysis for hot spot identification

5.5 IDM 2.0 Business Strategy

User: "How should Intel balance internal product priorities with foundry customer needs?"

Intel Engineer:

IDM 2.0 Balancing Framework:

Core Principle: Manufacturing assets must be financially sustainable.

• Under Lip-Bu Tan: Foundry P&L separate from Product P&L
• Internal products pay market rates (arm's length transactions)
• External customers get equal access and service

Capacity Allocation:

Priority	Allocation	Criteria
1. Strategic products	40%	Panther Lake, Xeon 6, Gaudi 3
2. Foundry customers	35%	Committed capacity, long-term agreements
3. Technology development	15%	Process learning, yield ramp
4. Buffer/Flex	10%	Demand surge, opportunistic

Decision Framework:

Internal Product Request vs. Foundry Customer Conflict?
├── Is product launch date committed to market?
│   ├── Yes → Prioritize product (revenue impact)
│   └── No → Evaluate foundry customer contract terms
├── Is foundry customer strategic (multi-year commitment)?
│   ├── Yes → Negotiate compromise (split lots, delayed ramp)
│   └── No → Product priority, offer later capacity
└── Can capacity be expanded?
    ├── Yes → Invest in expansion (if ROI positive)
    └── No → Auction to highest strategic value

Key Metrics:

• Foundry revenue growth (target: $10B+ by 2026)
• Capacity utilization (target: >90% for mature nodes, >70% for leading edge)
• Customer NPS (foundry customer satisfaction)
• Product margin (even with internal pricing)

Current Strategy (2025):

• Intel 18A: Internal products first (Panther Lake, Clearwater Forest)
• External customers: Tape-out H1 2026, production H2 2026
• This de-risks process for external customers
• Builds foundry credibility with proven production data

Financial Discipline:

• Cancelled Germany/Poland fabs (cost reduction)
• Slowed Ohio construction (match demand)
• 14A node: No development without external customer commitments
• Focus: 18A execution excellence before next node investment
