Logic Simulator |
The free Logic Simulator simulates digital logic circuits and state machines that are defined by a text file. Both basic parts, such as logic gates and flip-flops, and MSI (Medium Scale Integration) functions are supported.
There are two modes of operation - Hardware (HW) and Software (SW). The HW mode performs additional timing checks including flip-flop setup/hold times, race conditions and spike/glitch detection which are generally not applicable to computer science analysis.
The Logic Simulator uses the same simulator as the Logic Design Draw & Logic Design Auto tools, and will support all digital logic types: Combinational - Sequential - Synchronous - Asynchronous
Input Window
The Input Window describes the circuit to be simulated and its input/output signals. Data can be edited, cut and pasted, or loaded from a file.
Simulation features
Most input/output features of the Logic Simulator are identical to Logic Design Auto. In addition to the logic gates and flip-flops available in Logic Design Auto, the Logic Simulator supports a number of 54/74LS series MSI functions: LS138, LS148, LS151, LS153, LS157, LS163, LS164, LS181, LS193, LS194.
