Methods to avoid frequency locking in a multi-channel neurostimulation system using pulse placement

A multi-channel neurostimulation system, comprising:

• a plurality of electrical terminals configured for being respectively coupled to a plurality of electrodes;
• analog output circuitry configured for delivering a plurality of pulsed electrical waveforms respectively within a plurality of timing channels to the electrical terminals;
• and
• control circuitry configured for predicting sets of stimulation pulses within the pulsed electrical waveforms that will potentially overlap temporally, and substituting each of the potentially overlapping pulse sets with a replacement stimulation pulse, such that each replacement stimulation pulse is delivered within at least one of the respective timing channels, thereby preventing temporal overlap between the stimulation pulses of the respective pulsed electrical waveforms.
