/**
 * fakediode: Antenna tie-down diode with no connection between the DIODE
 * pin and the diode.  This is just the sky130_fd_sc_hd__diode_2 cell with
 * the contacts removed between the diode and the pin.  It is used by the
 * openlane synthesis flow to preemptively put antenna tie-downs close to
 * every pin without making a connection.  If the net needs an antenna
 * tiedown, the fakediode cell can be replaced by the real diode cell.
 *
 * Verilog wrapper for diode with size of 2 units.  Note that the wrapper
 * is around the original SkyWater diode base cell;  because the diode
 * has no function in verilog, there is no difference between the verilog
 * definitions of the diode and fake diode other than the cell name.
