Not open source, but:

Free software for boolean logic optimization, analysis, and synthesis
Logic Friday uses espresso for minimization and misII for gate diagram synthesis. Both programs are included with the download.


See http://sontrak.com/ - it's Windows-only, but I'd expect it to work with WINE on other platforms.

With Logic Friday you can:
    Enter a logic function as a truth table, an equation, or a gate diagram
    Enter functions with up to 16 inputs and 16 outputs
    Minimize a function with options of fast or exact minimization
    Automatically generate a multi-level gate diagram using gates chosen from a library
    Automatically minimize the number of standard gate packages
    Trace the logic state of each gate's inputs and outputs for a given input vector
    Compare logic functions
    Generate new functions as logical combinations of others
    View any function as a truth table, equation, or gate diagram
    Generate efficient, compact C code lookup functions from logic functions
    Save functions and gate diagram images to files
    Export and import truth tables as CSV files for editing in spreadsheet applications.

I can remember being able to impress people by doing a Karnaugh map to simplify a logic truth table. Guess that isn't much of a trick anymore... :-)

I have to admit that some of the FPGA tools that can synthesize an entire ROM into gate logic really impresses me. But this looks like an interesting tool for teaching STEM courses around logic design.

Thanks,
Jim
