Open Drain, Open Sink, Open Source Buffers
All rules given in “Output Buffer Syntax” on page 5-2 apply
with the following exceptions:
• Because open drain and open sink buffers do not have pullup
circuitry, do not specify the option xv_pu=nd_state_pu.
• Similarly, because open source buffers do not have
pulldown circuitry, do not specify the option
xv_pd=nd_state_pd.
See “Open Drain, Open Sink, Open Source Buffers” in the
Star-Hspice Manual.
