Hi, I was trying on the level shifter and the simulations went on an error. Is there any problem with the simulations?

When you use the level shifter, you need an extra line in your testbench to include the HVL standard cell library:

Copy code

.lib {PDK_ROOT}/{PDK}/libs.ref/sky130_fd_sc_hvl/spice/sky130_fd_sc_hvl.spice

There is an example of this in my example at https://github.com/RTimothyEdwards/sky130_ef_ip__rdac3v_8bit
