Re: talking about switch branches...

I am fairly sure the LRM prohibits contributions inside events.
In fact, you (Sri) reported this as Mantis item 815.
http://www.eda.org/mantis/bug_view_page.php?bug_id=0000815

I know many users have gotten themselves in trouble, trying to
contribute in an event like this:

  @(cross(...,+1))
    V(branch) <+ -1;
  @(cross(...,-1))
    V(branch) <+ +1;

when what they really wanted was
  @(initial_step)
    vout = 1;
  @(cross(...,+1))
    vout <+ -1;
  @(cross(...,-1))
    vout <+ +1;
  V(branch) <+ vout;

that is, they expected the contribution to be "persistent."
