### Setup
|
|
|
|
|
A template `.magicrc` file can be found in `magic/.magic_tech`. This
|
|
|
|
|
config file works with the SKY130 technology. Changes will need to be made to
|
|
|
|
|
the .magicrc file so that `PDK_ROOT` points to this repo. All the
|
|
|
|
|
relevant Magic tech files are also found in `magic/.magic_tech`.
|
|
|
|
|
|
|
|
|
|
The SKY130 model files are found in `sky130A/` which are used when
|
|
|
|
|
simulating a SPICE file in Ngspice.
|
|
|
|
|
|
|
|
|
|
A tcl script to generate SPICE from Magic layout can be found in
|
|
|
|
|
`magic/magic_spice_extract.tcl`. A tcl script to run LVS can be
|
|
|
|
|
found in `lvs/runlvs_single.sh`.
