cad/digital 0.31 MidnightBSD

Features: * Visualization of signal states with measurement graphs. * Single gate mode to analyze oscillations. * Analysis and synthesis of combinatorial and sequential circuits. * Simple testing of circuits: You can create test cases and execute them to verify your design. * Includes a simple editor for finite state machines (FSM). A FSM can then be converted to a state transition table and a circuit implementing the FSM. * Contains a library with the most commonly used 74xx series integrated circuits * Supports generic circuits. This allows the creation of circuits that can be parameterized when used. In this way, it is possible, for e.g., to create a barrel shifter with a selectable bit width. * Supports large circuits: The "Conway's Game of Life" example consists of about 2400 active components and works just fine. * It is possible to use custom components which are implemented in Java and packed in a jar file. See this example for details. * Simple remote TCP interface which e.g. allows an assembler IDE to control the simulator. * Components can be described using VHDL or Verilog. The open source VHDL simulator ghdl needs to be installed to simulate a VHDL defined component, and the open source Verilog simulator Icarus Verilog is required to simulate a Verilog defined component.
