flow I meet with problem about usage. Is there any small demo that similar to the following flow. Whether Magic can transfer .sp file to .gds?

Magic can generate a basic starting layout from a SPICE netlist if and only if there is a corresponding PDK with cell generator Tcl scripts. These exist for the open-source PDKs sky130 and gf180MCU. For those PDKs, if you start magic with the -rcfile <startup_script> option, then the startup script loads the device generators, and you can use the menu option File->Import SPICE or use the corresponding Tcl command in the Tcl interpreter.

But, assuming that you have Librecell-layout and Librecell-lib to take care of the top and bottom steps, then magic is capable of reading GDS and generating a full R-C parasitic extracted netlist.

When I run command "git submodule update", it always block at "Cloning into..." and no response just as the second image.

The main thing I see in the screenshot above is "permission denied" for writing into "/home/skywater-pdk".

But you do not need to be following those instructions. The skywater PDK will be cloned and installed automatically when you do

./configure --enable-sky130-pdk
make
sudo make install

in the open_pdks repository.
