fabless-foundry ecosystem

The fabless-foundry ecosystem is the division of labor that lets one company design a chip while another company manufactures it. **The separation changed who can build silicon.** A fabless company owns architecture, RTL, verification, firmware, software, and market strategy. The foundry owns process recipes, PDKs, wafer operations, and yield learning. Around them sit EDA tools, IP vendors, packaging houses, test providers, and materials suppliers. | Ecosystem layer | What it contributes | Failure mode | |---|---|---| | Fabless design | Product idea, architecture, and verification | Design bug or weak product fit | | Foundry | Process technology and wafer manufacturing | Capacity shortage or yield issue | | EDA and IP | Tools, models, libraries, and reusable blocks | Sign-off mismatch or licensing gap | | OSAT | Assembly, packaging, and final test | Package bottleneck or reliability issue | **The ecosystem is efficient because each layer learns faster inside its specialty.** It is fragile because a delay at any layer can hold the entire chip hostage.
