Complete the following steps to save the file with a new name:.When opening Multisim a blank file opens on the workspace called Design1.Multisim User Interface 1 Menu Bar 2 Design Toolbox 3 Component Toolbar 4 Standard Toolbar 5 View Toolbar 6 Simulation Toolbar 7 Main Toolbar 8 In Use List 9 Instruments Toolbar 10 Scroll Left/Right 11 Circuit Window 12 Spreadsheet View 13 Active Tab Start > All Programs > Circuit Design Suite 11.0.Multisim is designed for schematic entry, simulation, and feeding to downstage steps, such as PCB layout.It consists of tools that assist you in carrying out the major steps in circuit design.Multisim is a schematic capture and simulation application.Again, assuming the free/budget versions are comparable to the old one, of course.
What is multisim how to#
The schematic capture is kind of weird (I mean, everyone uses their own shortcut keys, and concepts of objects and how to connect and move and edit them, so it's not like this is unusual.), and keeping a complex design in sync with the PCB (Ultiboard, or via netlist output to others) can be tiring. PSPICE is probably better, and OrCAD (the schematic capture end of it, which is now integrated with PSPICE IIRC) I don't think is any worse.
What is multisim free#
Anyway, as SPICE goes, I would rank Multisim above LTSpice and Altium, and probably most free or budget packages (which I haven't seen or used, so I don't know for sure). Models using these elements simply aren't compatible, and will require between "some" and "a lot" of work to convert.

Anyway, PSPICE has its own (incompatible) digital primitives, LTSpice has another, Altium uses SimCode, Multisim uses some other kind of code, etc. The models that aren't, are large (50k+?) and encrypted (usually HSPICE), and require additional licensing to use (e.g., to enable the BSIM3 plugin for someone's transistor-as-in-monolithic-chip-level models). Most models are approximations of the real thing (both for speed and IP-hiding reasons). Talking about digital models is relevant because a lot of manufacturers write models just for one or a few environments, and that's it. Which is fun, because that logic output was driving a gate driver, so the switching circuit was shorted out for a few microseconds there, through no fault of my modeling. I have a lovely screenshot of a simple "74HC04" inverter that received an input voltage, and didn't produce (and propagate) events to the digital model. Just beware of what it is: analog and digital are two different domains, and events can be missed. The logic outputs then have to be updated: another event is scheduled, using the propagation delay. So, if an analog input voltage rises past a logic threshold, that's converted into an event. Whereas analog sim calculates the next timestep based on numerical tolerances, events are scheduled by the timing constraints written into the digital models. Event-driven digital is fundamentally different from analog simulation.
What is multisim code#
(At least as of a few years ago, being that Multisim v10 is the last I used.) It's a basic SPICE environment, so you get analog stuff, XSPICE elements (but they suck, and go largely unused), digital (via event-driven simulation, using some proprietary code - everyone makes their own flavor, because XSPICE sucks at digital), interactive elements, and emulation elements (I think there's 8051 and PIC something in there?).
