Hi, what is the recommended way for updating an open_pdk installation? Or is reinstalling with make the best way to go? I have a snapshot from last July and I am assuming the sky130 repo would have been updated since…

Running

make pdk

in your openlane directory will delete your current

$PDK_ROOT

before creating a new one. I assume that that's the standard way. If you need the SRAM macros,

export INSTALL_SRAM=enable

first. If you're using standard cell libraries other than

sky130_fd_sc_hd

, it's

make full-pdk

. You can set

export SKYWATER_COMMIT=xxxxxx

or

export SKYWATER_COMMIT=xxxxxx

if you want to use a specific commit, otherwise the version in

dependencies/tool_metadata.yml

will be used.
