BlackBoard – Circuit Layout.and Simulation
An Open Source “Learning EDA” Software which can setup circuit layouts. You may use it for stripboards, perfboards, breadboards, and even for plain circuitry or simulation. Creation and editing of symbols and elements on-the-fly using an integrated editor
The Library has more than 300 different elements and symbols. Has an Integrated SPICE simulation support with netlist generator. NGSPICE Frontend (comes along with NGSPICE for Windows).
These are some of the Components in the Library. Makes Setting up a circuit layout fun.
