Electronics CAD (ECAD) refers to software tools specifically designed for creating, analyzing, and documenting electronic circuit designs, including schematics and printed circuit boards (PCBs). It enables electronic engineers and designers to efficiently build and test circuits before physical prototyping.

🧭 Applications of Electronics CAD

• Schematic Capture

  • Create circuit diagrams using standardized electronic symbols (resistors, capacitors, ICs, etc.)

• PCB Layout Design

  • Design the physical layout of electronic components on a PCB

  • Routing of traces, placing pads, and layers

• Simulation & Analysis

  • Simulate the behavior of circuits before fabrication (analog/digital simulation)

• Component Library Management

  • Manage footprints, pin mappings, datasheets, and electrical properties of components

• Gerber File Generation

  • Output files used for PCB fabrication (includes copper layers, drill holes, masks)

• Embedded System Design

  • Design microcontroller-based systems with schematic and PCB integration
