Hi everyone. I'm working with MiM caps, but Xschem Symbol shows a question mark. How could I fix it?

<@U03HD0PTA0H> the text on the left (the question mark) should display an aproximate estimation of the capacitance, by using the area of the capacitor (W * L, in the example, 100). If expression is not evaluated my be you have an old xschem installation? ensure you do not have an xschem package installed from the linux distribution. For ubuntu:
`sudo apt-get purge xschem`
then follow instructions <https://xschem.sourceforge.io/stefan/xschem_man/install_xschem.html|here> to install xschem from git.
`git clone <https://github.com/StefanSchippers/xschem.git> xschem-git`
`cd xschem-git`
`./configure`
`make`
`sudo make install`

For capacitance to display ensure you are assigning W, L and MF:
`name=C3 model=cap_mim_m3_1 W=10 L=10 MF=2 spiceprefix=X`

From the picture above it seems the symbols are a bit old. The current mimcap displays like this:

Thanks a lot <@U01819B63HP>!! I solved the problem with your help.

Good!. What was the problem? this might help others facing the same issue...

As you said, I had an old xschem. I had installed Xschem from this.... <http://repo.hu/projects/xschem/releases/xschem-3.0.0.tar.gz> . The new version of xschem that I have now (from your github) works perfectly. Thanks!
