Hi @Stefan Schippers, @Tim Edwards , Thank you for your help and suggestions. I believe there is an issue during the installation and it seems like to be some threads related to Magic since another user @Saul Rodriguez is facing the same issue. Systems seem to be hanged after make command is executed (step 13 in http://opencircuitdesign.com/open_pdks/index.html ) : ..... git submodule init libraries/sky130_fd_sc_ls/latest git submodule init libraries/sky130_fd_sc_lp/latest git submodule update make timing May I ask for any recommendations at this point? What would be the best way to install open_pdks at the moment? Best Regards, Milad

The issue with magic only applies to version 8.3.305 which was only posted for half a day. "make timing" is known to be very slow, though.
