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, @Tim Edwards 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.
