   6 <p>During the aggression detection stage, it is possible to specify that only one signal can switch at the same time among a set of signals. Theses sets are specified in CROSSTALK MUTEX section :</p>
   7 <code>
   8 <cl>CROSSTALK MUTEX</cl>
   9 <cl>BEGIN</cl>
  10 <cl>    MUXUP {sig1, sig2};</cl>
  11 <cl>    MUXDN {sig3, sig4, sig5};</cl>
  12 <cl>    MUXUP {sig7, sig8, ..., sig12};</cl>
  13 <cl>    ...;</cl>
  14 <cl>END;</cl>
  15 </code>
  16 <p>
  17 In each MUXUP (MUXDN) section, only one signal in the list can rise (fall) at the same time.
  18 A signal can be listed at most in one MUXUP and in one MUXDN section. If two or more signals of a same mutex
  19 appear in the aggressor list of a signal, the one with the bigger coupling capacitance between
  20 the victim and this aggressor is considered to be switching at the same time.</p>
