I couldn't believe that hyperlynx can't initialize, so I just googled and
found the Mentor Users Manual for Hyperlynx.
Check out Page 40 Table 3-4 in Document
http://olgas.wheelnt.ru/FTP-root/Photo%20archive/Busya%202010-03/REL_PADS9.2_BETA1/full_install/evaluation_documents/hla_user.pdf
This is exactly the function you need to use to initialize the cap to the
starting voltage.
Hope this helps.
BR,
Gert

Betreff: [SI-LIST] Re: XAUI simulation -help needed
There's no way in Hyperlynx to initialize coupling caps. We replace the caps
with resistors and ignore the common mode. Typically zero ohm resistors work
fine, but often we'll replace the caps with a resistor equal to the cap's
impedance at the fundamental frequency of the channel.
