Cadence Design Systems
Cadence Design Systems delivers software and IP for electronic design automation, including IC and PCB design, verification, emulation, and system analysis. The EDA product lines (Virtuoso, Allegro X, OrCAD X, Xcelium, Innovus, JasperGold) are licensed desktop and compute software automated with SKILL and Tcl scripting inside the installed product, not network APIs, and Cadence publishes no machine-readable contract for them. The callable surfaces Cadence does operate are catalogued as separate API entries in this record.
