Layout Editor

Using the layout editor, the user can layout and hookup different types of logic gates. The Components section of the toolbar on the left of the display offers the user a choice of eight logic gates which may be placed anywhere at any 90 degree orientation on the workarea grid. The Edit toolbar section provides operations which let the user modify, delete or group entities on the layout workarea. The Wire offers features which let the user interconnect the various components together and to label the netlist in preparation for simulation.

Signal Display

The signal display shows both the input and output signals for the circuit in the layout workarea. A signal is displayed for each netlist that the user has named using the Label feature in the Wire section of the toolbar. The user may modify input signals using the mouse and subsequently simulate the circuit to display the appropriate output signals. The type of each signal (input,output or unknown) is determined automatically by the interface.
