eda tools overview

**EDA (Electronic Design Automation)** — the software tools that enable engineers to design, verify, and manufacture chips containing billions of transistors, without which modern chip design would be impossible. **The Big Three** - **Synopsys**: #1 by revenue. Design Compiler (synthesis), ICC2 (PnR), PrimeTime (STA), VCS (simulation), Fusion Compiler - **Cadence**: #2. Genus (synthesis), Innovus (PnR), Tempus (STA), Xcelium (simulation), Virtuoso (analog/custom) - **Siemens EDA (Mentor)**: #3. Calibre (physical verification — gold standard), Questa (verification), HyperLynx **Tool Flow** | Stage | Tool Category | Leaders | |---|---|---| | RTL Design | Editor/IDE | Any editor + linting | | Simulation | Logic simulator | Synopsys VCS, Cadence Xcelium | | Synthesis | Logic synthesis | Synopsys DC, Cadence Genus | | Place & Route | Physical design | Synopsys ICC2, Cadence Innovus | | STA | Timing analysis | Synopsys PrimeTime, Cadence Tempus | | Physical Verif | DRC/LVS | Siemens Calibre, Synopsys ICV | | Formal | Property checking | Cadence JasperGold, Synopsys VC Formal | | Power | Power analysis | Synopsys PrimePower, Cadence Voltus | **Market Size**: ~$15B annually, growing 15%+ per year **Licensing**: Per-seat or time-based. A full EDA license suite can cost $50K–500K per engineer per year **EDA tools** are the picks and shovels of the chip industry — every chip ever made was designed with them.
