About

Logisim-evolution is a completely free and open-source educational, cross-platform software for designing and simulating digital logic circuits. Project highlights: easy to use circuit designer logic circuit simulations chronogram (to see the evolution of signals in your circuit) electronic board integration - schematics can now be simulated on real hardware VHDL components (components whose behavior is specified in VHDL!) TCL/TK console (interfaces between the circuit and the user) huge library of components (LEDs, TTLs, switches, SoCs) Supports multiple languages and more!
