Is it possible to use sky130_fd_sc_hvl with openlane? I want to make a design that has 3.3V for some parts of it.

yes @User .In config.tcl add the following 
set ::env(STD_CELL_LIBRARY) sky130_fd_sc_hvl
c
Do you know if there are any examples of this. I made a copy of the inverter example from openlane and added that line to config.tcl but when I run the flow the synthesis gives me an error.
