Creating an Eye Diagram in MultiSIM Blue

[JALNH]

How do you create an eye diagram in MultiSIM Blue 13.0?  I read somewhere to create a macro and I created a text file for one to add to the "User Database."  Also, where are the components stored in the program?  Maybe I can dump the file there.  I'm very new to this so please forgive my inexperience.

Thank you for all your help.

Hi there,

Could you please give more details about your question? Exactly what type of diagram you want to create? Any specific circuit?

Hello Fernando.

Thanks for replying.

I cannot post or describe the circuit because it's proprietary.  I tried to attach a pdf describing how to create an eye diagram in Spice but I kept getting an error.  The eye diagram is a very important tool to visualize data patterns and I'm trying to create either a macro or a circuit.  The oscilloscope functions in MultiSIM do not allow this.  How can this be done?

Here are 3 sample macros that should work:

pi=4*atan(1)
mod(a, b) = (b)*(atan(tan(((a)/(b))*pi-pi/2))+pi/2)/pi
eye_sweep(p, d) = mod(time+(p)/2+(d), p) - ((p)/2+(d))

Best regards, Jesse.

Hello,

Thanks for the info. Multisim does not plot Eye Diagrams. If possible try to attach the pdf file again and I'll take a look.

Hello Fernando.

 I tried to attach a pdf describing how to create an eye diagram in Spice but I kept getting an error that says "The contents of the attachment doesn't match its file type."  It's a pdf file - there shouldn't be a problem with the "file type."

Is there an e-mail I can send it to?

Thanks and best regards.

Create a ZIP file and try to attach it.

Thanks for the information. The tutorials you attached refer to features available in other environments. Unfortunately you will not be able to use these methods in Multisim.

As mentioned before, Multisim does not support Eye Diagrams.
