Tcl/Tk based digital circuit editor and simulator
TkGate is a graphical editor and event-driven simulator for digital circuits with a tcl/tk-based interface. Supported circuit elements include basic gates (AND, OR, etc.), tri-state gates, adders, multipliers, registers, memories and mos transistors. Hierarchical design is also supported with support for user defined modules. Save files are based on the Verilog netlist format.
