Moreover, argue appellants, Bolcato does not provide for the
deficiency of Popescu because Bolcato injects a deterministic
current source for each noisy element with the frequencies and
amplitudes picked to emulate a physical noise spectrum, then
performs N + 1 simulation runs, first without the current sources
and then N times using the current sources with the phases of the
sinusoids varied between runs, citing page 889, left column.
Thus, appellants contend, Bolcato has no noise generation during
a simulation run but, rather, current source phase increments at
the beginning of each simulation run (see brief-page 3).
Appellants conclude that “Bolcato does not suggest putting a
noise source with each circuit element for simulation in Popescu
because Bolcato really does not use noise sources (i.e.,
something that is random during a simulation run). In fact,
Bolcato page 888, right column, fourth paragraphs of section A)
specifically avoids them” (brief, pages 3-4).
The examiner’s response is to agree with appellants that
Popescu teaches a circuit simulation using a single noise source
for an entire circuit. However, pointing to the same portion of
Popescu as do appellants (page 554, section 2), the examiner
argues that Popescu does not add precomputed noise after
generating the circuit output and that Popescu, in fact, adds the
