Electrical CAD Systems

The best free PCB design software available. It allows you to generate all the files required to take your project from circuit diagram to layout schematic to a circuit board built project. Gerbers (Extended RS-274-X), Excellons, BOMs, component lists and positions are possible along with DXF (import and export) and IDF for interfacing to mechanical CAD software. Supports the importing of Eagle CAD design files, circuit diagrams and libraries.

Free PCB design software. 1 to 16 copper layers. Board size up to 60 inches by 60 inches. Lots of options when generating CAM gerber files. You usually import a PADS netlist generated from a schematic capture program (TinyCad) then you can run connectivity checks to validate your layout against the schematic. Lots of layout design rule checks are also included. It even uses a free online auto-router.

The EAGLE Layout Editor is an easy to use, yet powerful tool for designing printed circuit boards (PCBs). It can create CAM files for EXCELLON GERBER. The limitations of the freeware version are as follows –

  • the useable board area is limited to 100 x 80 mm (4 x 3.2 inches).
  • only two signal layers can be used (Top and Bottom).
  • the schematic editor can only create one sheet.

The ElectricTM VLSI Design System is a complete Electronic Design Automation (EDA) system that can handle many forms of circuit design, including: Custom IC layout. Schematic Capture (digital and analog), Textual Languages such as VHDL and Verilog, Electro-mechanical hybrid layout, Programmable logic (FPGAs).
