gEDA Project - Electronic Design Automation tools

The gEDA project is working on producing a full GPL'd suite of Electronic Design Automation tools. These tools are used for electrical circuit  design, schematic capture, simulation, prototyping, and production.

gEDA  - Electronic Design Automation

Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

Raspberry Pi BitScope

A fully integrated Test bench based on Virtual Instruments - mixed signal oscilloscope, logic analyzer, spectrum analyzer and waveform generator using BitScope connected via USB or Ethernet to the now very popular Raspberry Pi.

Raspberry Pi BitScope

Regardless of which BitScope you choose, the new BitScope Library is also available making it easy to create your own embedded test, measurement or data acquisition applications using BitScope and Raspberry Pi. Program in C/C++, Python or Pascal using an easy to use programming API.

 Raspberry Pi BitScope

BitScope Model 10 - World's Smallest Mixed Signal PC Based USB Oscilloscope!

BitScope Pocket Analyzer. It's a problem solver that fits in the palm of your hand. Perfect for designing, prototyping and debugging!

It has 100 MHz bandwidth, up to 40 MSps logic, simultaneous waveform and clock generation and offers serial control of connected devices.  It's the ideal tool for prototyping analog electronics projects, digital and logic circuits or Arduino, Raspberry Pi and other microcontroller based systems with busses, sensors, servos and I/O.

See a 3D View of your Eagle Cad Layout

With Eagle3D it is possible to generate a 3D View from your Board Layout. This will help you iron out mechanical clashes, thermal conflicts. Serviceability and Accessibility issues too.

On Panel PCB's Like front/back panels. Usability errors may become visible in this simulation. Connector and wiring layout can be better judged on 3D and strain relief and cable management can be planned in power electronics designs.

In sensitive analog circuits; thermal, leakage or guard rings can be inspected. In RF circuits; the shielding, tracks and components can be studied for unwanted coupling, crosstalk or leakage. Finally safety factors also can be judged keeping the enclosure 3d or cabinet in hand.

Now we have low cost 3D CNC prototype makers. Rapid prototyping - additive or laser erosion. You can probably use this as a input for such a machine. Then you can fix it in a cabinet and complete the Mechanical Simulation. This will save wastage of parts, time and pcb's during prototyping.

Arthernet - AVR Ethernet Modul

The heart of the module is the well-known ATmega128 microcontroller from Atmel®, which in addition to the Realtek RTL8019 Ethernet controller also has a USB and optionally an RS232 or CAN interface, enabling universal use of the module.

On the relatively small board with only 100mm x 80mm edge length, not least for reasons of space, a CPLD from Xilinx® is used. It contains the address decoder necessary for addressing up to 512KB Ram plus bank registers and is also responsible for the chip select control of the memory mapped and SPI devices.
