Hello,

I would like to delay and invert a differential signal w.r.t to
another in HSPICE. I have attached the spice code I tried to get this
to work but the sim seems to hang when I run it. With the lines
starting with "Etin1" and "Etnin1" commented out or the nodes "in1"
and "nin1" held static I do not seem to have the problem.

Thanks in advance for your suggestions/help.

Vipul.
