Sircuit

SFML 2D drag'n'drop logic circuit simulator. A descendant of CCircuit.

Features

• Objects: AND, OR, XOR, NOT, Switch, Randomiser, Bit (flip-flop), Indicator, Panel
• Pan & zoom
• Load & save, both board & component
• (Hopefully) smooth graphics
• Snap-to-grid, visible when zoomed in
• Pause & step
• Probably cross-platform
• Pre-built 8-bit components: adder, incrementer, 7-segment display, Read/Write memory

Download, Build, and Run

On Debian et al:

sudo apt install libsfml-dev cmake make
git clone --depth=1 https://github.com/phunanon/Sircuit.git
cd Sircuit && mkdir build && cd build
cmake ../src
make
./Sircuit

Controls

• left-click & drag: pan screen, move objects, move panels and their objects, and select panel as a 'component'
• left-click: start or end object-to-object connection
• right-click: 'click' some objects for functionality (e.g. Switch, Bit), create object-to-object connection
• left-click + left-shift: delete object
• F1: pause/unpause
• F2: step
• left-ctrl + O: Open session
• left-ctrl + S: Save session
• left-ctrl + I: Insert component
• left-ctrl + C: Save component
• C: Copy component
• AND, OR, XOR, NOT, Switch, Randomiser, Bit, Indicator, Panel

Also, left-alt can be left-click, space can be right-click.
