@User @User I am trying to install specific liberty files sky130_fd_sc_hd__ss_025C_1V80.lib and sky130_fd_sc_hd__ff_025C_1V80.lib for my work as a part of vsd hdp program. Can you kindly guide me on how should I proceed. I already have the pdk install using using openlane build script provided by vsd.

They would go into the installed PDK, which would be, for example,

${PDK_ROOT}/sky130A/libs.ref/sky130_fd_sc_hd/lib/

.
