Exporting parameter sweep simulation data to Excel instead of grapher

[ashifulk]

Is there a way to do a parameter sweep and just have the data export straight to a Excel or text file instead of the grapher?

I need to do multiple parameter sweep (about 100 value changes) and I just need to know the value at a node in my circuit after 2us. I know I probably can't do this but if I can just export the data to Excel instead of looking at the analog graph I can just pull out the data from there.

Hi

All simulation data will appear on the grapher but from here there is an option to export to Excel.  A Select Tools>>Export to Excel in the grapher.

There is also another option, you can use the LabVIEW Multisim API.   Let me me if you have LabVIEW.

Hi Tien,

I have LabVIEW but I don't have the Controls Module. Can I still use the LabVIEW API to do this?

If you are running Mutlisim 13 and LabVIEW 2013, when you install Multisim the API is installed automatically.

For older LabVIEW versions, you have to install the API.  Have  a look at this link:

Let me knwo what  Multisim and Labview version you are using and what parameter you want to sweep, I will see what I can do.

Can I have two installations of LabVIEW on the same computer (LabVIEW 12.0 and 13.0)? I really don't want to un-install my LabVIEW 12.0.

Actually, if you run the Mutlisim 13 installation, there is an option to install the API for LabVIEW 12, so you don't need LabVIEW 13, sorry forgot to mention that previously.

In LabVIEW, you will find the Multisim connectivity in Connectivity Function palette as shown in the attached screen shot.

I was thinking that you can write a LabVIEW VI to tell Multisim to simulate 100 times and each time use a different parameter and then output result in table. 

In Multisim, select Help>>Find example>>LabVIEW Multisim API Toolkit

Is it possible to do a transient analysis in LabVIEW using this toolkit? I don't see it. When I try the AC Sweep it seems to work but the "Run" one doesn't work.

I tried to use the "Run" VI to do a transient analysis but I keep getting an error. I have attached the VI I was using and the circuit. If you can take a look at it and let me know what is wrong I would really appreciate it.

Thank You.

Attached is an example VI to will run a transient analysis 10 times, each time the capacitor C7 value is changed.  By the way, C7 is the lower capacitor in your circuit.  I set the output to an array, but you can alter this for your purpose.  Let me know if you have any questions.
