Is it possible to call the `sky130A.magicrc` file by doing `magic -rcfile sky130A.magicrc` without having this file into the same folder where I'm running magic? as when using the tech file (where I can run `magic -T sky130A.tech` wherever I want because I already added this file into the path `cad/lib/magic/sys/`)?

Yes, you can do `magic -rcfile /path/to/sky130A.magicrc`.  I take the further step of defining an alias in my Linux .login file:
```alias magicsky 'magic -d OGL -rcfile /usr/share/pdk/sky130A/libs.tech/magic/sky130A.magicrc'```
so that I can just type `magicsky` and it comes up running with the right arguments.

Jumm, <@U016EM8L91B> then what would be the difference between this two ways of opening magic:
1. `magic -d XR -rcfile /path/to/sky130A.magicrc`
2. `magic -d OGL -rcfile /path/to/sky130A.magicrc` 

Just the graphics interface.  `-d OGL` is OpenGL;  works great except when it doesn't (!).  When it doesn't, `-d XR` (Cairo 2D graphics package) works.  In the early days of libcairo, when I was first using it, it could be substantially slower than OpenGL.  Recently, I haven't noticed any particular performance difference.
