Electronic Design Automation software enables engineers to design, simulate, verify, and prepare semiconductor chips for manufacturing. Without EDA tools, modern chip design (billions of transistors) would be impossible.

EDA Tool Categories

RTL Design: Write hardware description language (Verilog/VHDL). Tools: text editors, linting. Logic Synthesis: Convert RTL to gate-level netlist. Tools: Synopsys Design Compiler, Cadence Genus. Place & Route: Physical layout of standard cells and routing. Tools: Synopsys ICC2, Cadence Innovus. Verification: Confirm design correctness. Tools: Synopsys VCS, Cadence Xcelium (simulation); Synopsys Formality (formal verification). Physical Verification: DRC, LVS, antenna checks. Tools: Synopsys ICV, Cadence Pegasus, Siemens Calibre. Analog/Mixed-Signal: Schematic and layout for analog circuits. Tools: Cadence Virtuoso. DTCO: Design-Technology Co-Optimization for advanced nodes.

Major EDA Vendors

• Synopsys: #1 market share. Strong in synthesis, P&R, verification, IP. • Cadence: #2. Strong in analog, custom design, P&R, signoff. • Siemens EDA (Mentor): #3. Strong in physical verification (Calibre), DFT, PCB.

Design Flow

Spec → RTL → Synthesis → Floorplan → Place → CTS → Route → Signoff (timing, power, DRC, LVS) → Tape-Out → Mask Data Preparation
