Circuitlogix




CircuitLogix is an equipment required to test and design electronic circuits. The student version is made available at no cost to students and is intended purely as a learning resource to improve the student's knowledge and understanding of electronics. CircuitLogix supports Analog , Digital , and mixed-signal circuits, and its SPICE simulation gives accurate real-world results. The Graphic User Interface is user-friendly and allows students to quickly and easily draw, modify and combine analog and digital circuit diagrams.

CircuitLogix was developed by Dr. , which is the largest electronics program in the world with over 10,000 students in 37 countries.

CircuitLogix is a ''mixed-mode'' Schematic Editor and includes both analog and event-driven simulation capabilities. This means that any simulation may contain components that are analog, event driven (digital or sampled-data), or a combination of both. An entire mixed Signal Analysis can be driven from one integrated schematic. All the digital models in CircuitLogix provide accurate specification of propagation time and rise/fall time delays.

The event driven Algorithm used by CircuitLogix is general purpose and supports non-digital types of data. For example, elements can use real or Integer values to simulate DSP functions or sampled data filters. Because the event driven algorithm is faster than the standard SPICE matrix, simulation time is greatly reduced for circuits that use event driven models in place of analog models.

Mixed-mode simulation is handled on three levels by CircuitLogix: (a) with primitive digital elements that use timing models and a built-in 12-state digital logic simulator, (b) with subcircuit models that use the actual transistor Topology of the Integrated Circuit , and finally, (c) with In-line Boolean Logic expressions. These two modeling techniques use SPICE to solve a problem while the third method, digital primitives, use mixed-mode capability.

The full version of CircuitLogix includes over 4,000 device models, as well as 8 virtual instruments. It also includes 3DLab, which is a software product that combines an interactive 3-dimensional learning environment and "real world" electronic devices and tools to enhance the user's comprehension of electronics. 3DLab virtual components include Batteries , Switches , Motors , Lamp s, Resistors , Inductors , Capacitors and instruments including Oscilloscopes , Signal Generator s, and Frequency Counter s.
