I use Orcad's PSPICE student version, but I'm not so satisfied with if
It misses many mosfets, and voltage regulators like the 317, in its database
And I haven't found how to add libraries or parts. I even think it's impossible in the student version
wich one are you all using? I'm looking for a free one, with many parts and/or with the ability to add new parts |

I use Switchercad III (aka LTSpice) or Winspice, depending on
what I want to do. The first one is free, Winspice is actually
shareware, but there are no restrictions in it and can be used
for free.

there was an investment, however.
Multisim allows you to create new parts -- either for simulation or board design or both. This I have done for MOSFET's bipolars, diodes, opto-couplers, vacuum tubes etc. The process isn't exactly intuitive, however, and you will need a couple tries to get it right, the program allows you to draw the device, place nodes, connect the nodes to the model and insert the model as a text file. I believe that there is a student version available.
btw, YES, there is an opto-coupler SPICE model, something long sought after -- it's on the PDF for the Agilent HCNR-200 device. Why's an optocoupler spice model important? -- if you amplify the output (since photodiodes have large capacitance) you will almost certainly put the device into oscillation if not properly compensated. The HCNR-200 is an analog opto-coupler. Very helpful in noisy environments. |

I have used the following:
Winspice3 - a command line front end for spice, works good you have to add models in the .cir file
Nutmeg - I did a lot of work using this for one project, works ok.
Both the above are not the click to add part types, you must create your own .cir fies first using a text editor.
I have the Orcad student version - this program is not user friendly, very difficult to drw skiz and then run simulations.
I have used another one of the big spices at work - my mind can't remember which one but it also is NOT user frendly.
For ease of use and a progrem that works great try the free Demo TINA Spice at:

I use Circuitmaker 2000 Professional. Not flawless, but nothing that I haven't been able to overcome. The student version has a 60 part limit. The fully functional demo copy runs out after 30 days, and can't be reinstalled, or so they say. The professional copy is US$1000, but I think is available to students for much less. CM2k has multi=pane simulator, and doesn't require preset points to view waveforms. TraxMaker comes with it, for PCB layout. There's also a TraxCAM for creating a 3D model of the board. :rolleyes: I've been too busy to test that, tho.

| does anybody know how I can add parts to my oracad pspice student? |

I use SIMextrix from Newbury,
http://www.newburytech.co.uk/
Has an integrated schematic editor that is easy to use. The demo version is limited in circuit size, but depending on model you can get away with two full-blown opamps in one circuit. Accuracy seems good enough, though I have questions with the behaviour of opamp models near open-loop operation.
I think ALW uses the same. |

Hi all,
My preferred Spice Simulator is SIMetrix, my second is Tina, but all the two very expensive for a ocassional use.
I finally have buy SuperSpice, in:
www.anasoft.co.uk
The demo version allow a reasonable size circuits, but also have a student/beginner version for a low cost that allow big size circuits.
The software is in constant development and the support is good. Well, download the demo version and decide yourself. I think that is the more cheap altenative availlable.
Happy days,

As a guy at work says,
"If you don't want wrong answers, don't simulate" ... |

| Spectrum Software's Microcap is easy to use and learn and they have an evaluation version that is free. |

Orcad and SwitcherCAD III, the latter is much easier to use.
Does anyone that uses SwitcherCAD know how to add parts like MOSFETS? |

thanks all
but since I've made several shematics with my orcad pspice demo, and they won't certainly work on another spice based simulator, I'll stay with pspice
I've read (on this board) someone's post, in wich he said he managed to add models to pspice student
Now, I "only" need to know how he did this :xeye: |

Hi all,
I have forget, some of yours visited the web page of pcb-pool:
www.pcb-pool.com
In the section 'Downloads' yours can see that have a 'pcb-pool version' of Target 3001!.
The only limit is that, the output files are only valid for pcb-pool so, if yours like made your own pcb's, this program don't are usefull.
But the other parts of the program are fully functional: schematic capture and simulation and, as say the web page: totally free, no limits.
If someone need a Spice Simulator, and don't like the limits of the Students versions, of use a illegal copy of a commercial software, this have a professional Spice for Free.
Happy days
