in

configure

scripts the

--prefix <dir>

is the root directory where software usually installs its stuff, usually in the

<dir>/share

,

<dir>/bin

,

<dir>/lib

,

<dir>/etc

,

<dir>/include

directories, so the question is probably whether to use

share/pdk/sky130A

or

share/sky130A

. SInce i think open_pdks is not limited to just one pdk, using

share/pdk/sky130A

looks correct, where

share

is standard installation for shared files,

pdk

identifies the software (open_pdks) and

sky130A

identifies the specific process node/foundry.
