top_refgen	The REFGEN block (sky130_fd_io__top_refgen) is used to provide the input trip point (VINREF) for the differential input buffer in SIO and also the output buffer regulated output level (VOUTREF). Verilog HDL for “sky130_fd_io”, “sky130_fd_io_top_refgen” “behavioral_tmp”.	cell	sky130_fd_io__top_refgen
top_refgen_new	The REFGEN block (sky130_fd_io__top_refgen) is used to provide the input trip point (VINREF) for the differential input buffer in SIO and also the output buffer regulated output level (VOUTREF).	cell	sky130_fd_io__top_refgen_new
top_sio	Special I/O PAD that provides additionally a regulated output buffer and a differential input buffer. SIO cells are ONLY available IN pairs (see top_sio_macro).	cell	sky130_fd_io__top_sio
top_sio_macro	sky130_fd_io__sio_macro consists of two SIO cells and a reference generator cell.	cell	sky130_fd_io__top_sio_macro
top_xres4v2	XRES (Input buffer with Glitch filter).	cell	sky130_fd_io__top_xres4v2
