Abstract

Systems and techniques are provided for a multichannel waveform synthesis engine. A phase counter module counts to a value corresponding to a number of phases available, outputs a phase counter value indicating a current phase, and resets the phase counter value when the phase counter value reaches a phase counter reset value. Several channels each output a waveform. Each channel includes a phase module that receives the phase counter value output from the phase counter module, and activates an activation signal when the phase counter value indicates a phase assigned to the channel from the number of phases available. Each channel includes a pulse width module that receives the activation signal, and when the activation signal is activated, activates a waveform for a period of time indicated by a pulse width assigned to the channel, and deactivates the waveform after the period of time indicated by the pulse width assigned to the channel.
