HOW TO SIMULATE LOGICWORKS 5 SIMULATOR
While clearing the unknowns using the simulator command certainly has itsuses, it is better to explicitly place the simulation in a known state. What is thevalues displayed on the probes? Is this an inconsistent starting state for thesimulation? If so, why? One way to initialize the simulation to a known state is to use the ClearUnknowns command under the Options menu. In the absence ofother information, LogicWork assumes that all circuit nodes are undefined. LogicWorks(TM) understand the values logic0, logic 1, undefined ( "X" ), as well as high impedance ( "Z" ). The simulator must commence its operation making some assumptions about theinitial values of all circuit nodes. Place probes at the outputs of the three inverter.What value do they read out? Feed the output of the last inverter stage back as aninput to the first stage.

It willbe useful to remember how to use the Device Editor introduced there.īegin by invoking LogicWorks(TM), and create a schematic with threeinverters in series. Look back at Lab One if you need to review the use of LogicWorks(TM).
HOW TO SIMULATE LOGICWORKS 5 SOFTWARE
* Understand the limitations of the software simulator for simulating circuitswith feedback, particularly for modeling race conditions, and how to establishinitial conditions for the simulator. *Ĝonstruct a two element shift register and determine the conditions underwhich the introduction of clock skew leads to incorrect results. * Simulate positive and negative edge-triggered D flip-flops. * Simulate R-S and - latches constructed from cross coupled NOR gates and NANDgates respectively. * Simulate ring oscillators constructed from inverter chains. In this laboratory, you will gain experience in using LogicWorks(TM) tosimulate latches, flip-flops, and some simple shift register circuits. LogicWorks can be both an educational tool, that helps you practice your capability to use digital logic concepts, and a very efficient test tool that can determine the viability of a circuit design.Logic Simulation of Circuits with Feedback Last and not least, the LogicWorks export files are compatible with the more complex and powerful DesignWorks application: you can draw your test circuit in LogicWorks and then you can use DesignWorks for a more in depth analysis.
HOW TO SIMULATE LOGICWORKS 5 MANUAL
To learn more about what you can achieve using LogicWorks, you can consult the extensive user manual that in included in the Help area. The LogicWorks Simulator can show multiple signals at the same time, enables you to create a single timing value for a group of signals and comes with built-in support for ROMs, PLAs and RAMs. Since the editor is connected to a digital simulator, both the device parameters changes and the signal connections changes are expressed in timing waveforms that will be visible in the Design Timing area. The LogicWorks editor enables you to copy/cut/paste circuit elements, can reroute lines when you move symbols, allows you to set up your own device symbols and define their internal circuit and much more. Moreover, you can make your own text annotations. To get started, you must draw the circuit in the schematic editor: it comes with interactive connection tracing (it will automatically detect signal line connections), bussing and multi level undo and redo capabilities. LogicWorks offers you the possibility to simulate the effects of a certain circuit: this way you can test its viability without actually taking the time to make the physical connections between different instruments. The app is great as an educational tool since it allows you to practice digital logic concepts. LogicWorks provides simple tools and an organized environment for quickly creating visual representations for circuits.
