Chip design: tools, licensed blocks and physical implementation
A modern processor holds tens of billions of transistors. Nobody draws that. It is assembled from licensed blocks and generated by software from a functional description, and the two industries that supply those — design tools and design intellectual property — are among the most concentrated in technology.
In one sentence
Chip design is the process of specifying a circuit's function, assembling it from designed and licensed blocks, and transforming it into a manufacturable layout using automated design software.
The flow runs from a description of behaviour, through logic synthesis into gates, through placement and routing into a physical layout, to verification that the layout is manufacturable and matches the intended function. Every stage is software, and the software is supplied by a very small number of firms.
Alongside the tools sits the licensed block market. Processor cores, memory controllers, high-speed interfaces and standard cell libraries are licensed rather than designed in-house, because designing them is expensive and they are not where a product differentiates. That market has its own concentration and its own strategic weight.

What depends on this
Other pages in this map that name Chip design as something they cannot do without.
- Artificial intelligence · AI computeAI acceleratorsAn accelerator is tens of billions of transistors placed, verified and signed off in an EDA flow using bought-in interface blocks. Without that flow the design cannot be taped out at all.
- SemiconductorsFoundry and capacityCapacity is only worth what customers can design against it. Without kits, certified tools and licensable blocks a fab has wafers nobody can order.

How these pages are written
Each page explains one technology in plain language, states what it depends on, and names companies by what they supply at that step. Company roles are described qualitatively and deliberately carry no market shares, revenue figures or rankings — those change faster than an explainer can, and a stale number is worse than none. Ticker links point at company pages on this site and are provided for reference only.
Nothing here is investment advice, a recommendation, or a forecast. A company named on a page about a technology is not thereby a good investment, and the chokepoints described are structural facts about supply chains rather than predictions about prices. Technology moves; where a page describes something as unresolved or in development, that was true when it was written.
