LogicWorks is the schematic drawing and interactive circuit simulation package from Capilano Computing Systems that has set the standard for demonstrating digital logic design principles and practices while producing professional-level results. As circuit designs become more complex, software tools are taking on increasing importance in the system design process. LogicWorks 4 helps teach the concepts of using these tools in a variety of design situations in electrical and computer engineering, a nd computer science. With LogicWorks 4, installing and using this interactive tool has never been easier. The friendly user interface allows students to begin designing and testing circuits in minutes without the need for complex manuals. LogicWorks 4 builds on the success of the previous version by adding new features that expand the utility of the package beyond teaching digital design concepts. The software's new export capabilities means LogicWorks 4 can be used as the central design entry point for demonstrating a number of important design technologies such as analog systems, FPGAs, and VHDL synthesis.
