LabVIEW Multisim Connectivity Toolkit Beta Discussion

i think my SPICE circuit netlists that randomly written is not valid netlists create the problem...but, when I update my multisim to 10.1.0.1, it's working without error.... thanks god!

sorry...correction for previous post...not because of the update, but I change to more powerful PC...

is it possible to use the GetImage function to get the circuit image from netlist..I tried, but the circuit doen't appear... Other question, is it possible to convert the netlist into ms10 file back?

Hi Rahairi,

 

The Get Circuit Image method is only going to take a still-photo of the circuit that is open in Multisim. And by that I mean a captured circuit. A netlist by itself is just a list of connections, and it does not includes information about the graphically captured schematic, in other words, it knows how components are connected, but it does not knows how the user drawed the circuit.

 

For Multisim to get a circuit image, you'd need to have drawn the circuit in the capture area. If you already have a captured circuit, and you just need to change component values, you have VIs in the toolkit that will allow you to change the value of components without compromising the circuit drawn.

 

You cannot "convert" a netlist into a ms10 file just like that. However, if from within Multisim, you open a netlist, Multisim will try to draw the circuit from reading the netlist... however, try it so you can see what outcome you get from not having the capture information first, once you have imported this netlist now you can then save it to a ms10 file, but from within Multisim.

Ok..thanks for explaination..seem like I can't add the circuit image feature in my program but it's still ok..

FYI, your multisim toolkit is really helping me in my final year project..

I wish I would have had a workaround for you. On any case, once you are finished with your project, we would like to hear how that went, and how you used the toolkit. As you saw, it is located in the NI Labs website, since we are still in the process of learning the way it can be used. We have many lead users with very interesting applications, but we want to see where else it can be useful.

 

The main reason behind this, is because the more we learn about what you need to do (like your previous post) the better we can plan for that functionality to be exposed in releases to come.

Nestor, need your help once again....I decided to run AC simulation to get the circuit frequency response but I really confuse about the variables unit in the raw result file. Before simulation, I set sweep type in decade and vertical scale in desibel...for example...

 

Plotname: AC Analysis
Flags: complex
No. Variables: 2
No. Points: 101
Variables:
    0    frequency    frequency grid=3
    1    $2    voltage
Values:
 0    1.000000000000000e+000,0.000000000000000e+000
        9.960331378547194e-001,-6.285797114469585e-002

 1    1.258925411794167e+000,0.000000000000000e+000
       9.937275015207741e-001,-7.895031749280994e-002

 

there are four variables here...I think the first one is the frequency in hetz but which one is gain in dB? Is it the last one?

I would assume yes. I would instead recommend that you run the same analysis in Multisim and compare these values with the Grapher in Multisim. In that way you will have a clear idea of which one it is. You have four sets of data because AC analysis returns the magnitude (x and y) and the phase (x and y). Run the same analysis in Multisim. Otherwise let me know and I'll figure it out.

I think I've figure it out. The below value is the node 2 voltage in volt because i set the node 2 to be the output voltage and the next one is angle in degree. In the grapher in multisim, the first value is -17.2....(in mili),  I think the value of 10log(9.960331378547194e-001).

HI...I almost finish my project and it seems to work well except it was running about one day to complete all simulations and sometimes multisim wasn't responding when it was closed after the simulation done. But I can still continue my simulation by clicking 'continue' button when error windows show up. Check out my lowpass filter circuit (fc=3kHz) and its frequency response after evolving about 6000 samples.
