Logisim-evolution

Logisim-evolution is a digital logic design and simulation tool that allows users to build and test virtual circuit boards on Linux systems. It provides an educational environment where students and engineers can place gates, flip-flops, and input-output pins onto a canvas to observe how signals propagate through combinatorial and sequential logic circuits in real time. The interface includes oscilloscope views and debugging features to trace signal states across complex networks. Users can also bundle circuits into subcircuits to construct hierarchical designs, facilitating the creation of larger processors or arithmetic logic units within a single workspace.
