Having an initial circuit design is one thing. With Multisim, the scope simulations are sufficiently complete that you even need to click the ON button. It’s especially important that students are exposed to more than one brand of control interface although often this is impractical with real instruments. Or, you can probe circuit nodes with a virtual oscilloscope to help understand phase relationships.įrom a teaching perspective, having both Tektronix and Agilent Technologies scopes available for every student in a course is a big deal. Once a representative schematic is assembled, you can attach a virtual multimeter to various points to check DC bias levels. In addition to extensive component and AC/DC source libraries from which the circuits are constructed, several generic and manufacturer-specific test tools also are provided. Of course, you don’t have to be a student to appreciate Multisim’s ease of use and comprehensive features. Instead of directly interacting with SPICE, you are presented with a number of abstracted tools that keep the focus on your circuit design, not on the intricacies of simulation. Multisim is promoted as a teaching tool, and its advantages are easy to see. We chose to explore the circuit simulation capabilities available in an evaluation version of Multisim downloaded from. The National Instruments (NI) Circuit Design Suite 11.0 includes both Multisim™ circuit simulation and Utiliboard™ PCB layout applications. To become more familiar with typical capabilities, we decided to evaluate a modern circuit simulation program.
Nevertheless, in contrast to sports, circuits can be precisely modeled, which provides a very good chance of first-time design success. So too, circuit design isn’t really completed until thousands of the same circuit have been built that all perform to the specification. Regardless of how obvious an outcome may be, until the game is played, the predicted result can only be an estimate based on experience and hunches. As any sports fan knows, you get prognostications from the pundits.
