Cadsoft Eagle

One of the best, easy to use,widely supported and used PCB designing software is Cadsoft Eagle. It has many features, widely expanding libraries and even you can create your own libraries(a little advanced).It even has the feature of autorouting. Can support up to two layers of PCB. Some of the Components of Eagle are Schematics, PCB, CAM Processor.You can even create a 3D Image of the files using the user language programs and Eagle 3D software linking with POV-Ray Image viewer and creator.

 

Schematic Editor

• Up to 999 sheets per schematic
• Icon preview for sheets
• Sorting sheets with Drag&Drop
• Cross references for nets
• Automatic generation of contact cross references
• Simple copying of parts
• Replace function for parts without loss of consistency between schematic and layout
• Online Forward&Back Annotation between schematic and board
• Automatic generation of supply connections
• Automatic board generation
• Electrical Rule Check (error check in the Schematic and consistency check between Schematic and Layout)
• User Defined Net Classes for Via Size, Wire Width and Clearance

Layout Editor

• 4 x 4m (about 150 x 150 inch)
• Full SMD support
• Support of Blind and Buried vias
• Rotation of objects in arbitrary angles (0.1degree steps)
• Components can be locked against moving
• Texts can be placed in any orientation
• Dynamic calculation of signal lines while routing the layout
• Magnetic pads function
• Tracks can be drawn with rounded corners in any radius
• Mitering to smooth wire joints
• Design Rule Check for board layouts (checks e.g. overlaps, measures of pads or tracks)
• Copper pouring (ground plains)
• Package variants support
• Differential pair routing
• Meander command for length compensation of signals
• Support of assembly variants
• User definable, free programmable User Language to generate data for mounting machines, test equipments, milling machines or any other data format
• Output of manufacturing data for pen plotters, photo plotters and drilling machines with the CAM Processor

Autorouter

• Fully integrated into basic program
• Routing grid down to 0.02 mm (about 0.8 mil)
• Basic engine for the Follow-me-router, a tool that supports you in manual routing; the trace of a selected signal will be calculated automatically
• Ripup&Retry algorithm
• User definable strategy by cost factors
• No placement restrictions
• Uses the layout’s Design Rules
• Change between manual and automatic routing at any time
• Up to 16 signal layers (with user definable preferred directions)
• Full support of Blind and Buried vias
• Takes into consideration various net classes

CAM Processor:

• helps in printing gerber files for printing PCB top and bottom layers
• Full support to two layers
• User selectable different file formats
• Suports different sized boards up to 4mx4m

User Language Programs (ULPs)

ULP is a C-like User Language for data export and import for the realization of self defined commands. Most commonly use, but not limited to, exportation of custom BOM, creating library components, detailed statistic reports of schematic and board designs.
You can even simulate the digital and analog circuits using B2 Spice linking it with Eagle.Visit the website for more details. Download the freeversion from here
