eq or = equal to
ne or <> not equal to

lt or < less than
ge or >= greater than or equal to

IO redirection is disabled for the stop command, since the relational operations conflict with it (it doesn't produce any output anyway). The values above may be node names in the running circuit, or real values. If more than one condition is given, e.g. stop after 4 when v(1) > 4 when v(2) < 2, the conjunction of the conditions is implied.
