Hi,

I would like to create a voltage divider and add the voltage divider to the user library. I want to create a mask for the voltage divider which asks how many resistors will be used on the high side of the voltage divider.

For example, the number of pi sections in “Pi-Section Line” (it is a component in Plecs) is variable and users can assign section numbers. I would like to have the same for a voltage divider.

If someone can help me I really appreciate it. Thanks.

Vefa

Hi Vefa,

This is all documented in the PLECS User Manual (sections on “Masking Subsystems” and “Libraries”). Additionally, you can find tutorials on our website on this topic (#108 and #109 - [https://www.plexim.com/support/tutorials](https://www.plexim.com/support/tutorials)). I hope this helps, but if you have a specific question feel free to post it here.

Thanks,

Kris
