Methods and systems for generating stimulation waveforms for a neurostimulation therapy

A system for generating a stimulation waveform for a neurostimulation therapy, the system comprising:

• a user interface configured to receive a user input indicative of a target stimulation waveform;
• a radio frequency (RF) subsystem configured to establish a communication link with a neurostimulation (NS) device that includes first, second, and third generator circuits configured to generate different first, second, and third types of stimulation waveforms, respectively;
• a controller circuit operably coupled to the user interface and the RF subsystem, the controller circuit is configured to:
• calculate a timing resolution of the target stimulation waveform;
• determine target amplitude resolutions of the target stimulation waveform;
• identify whether a mathematical relationship exists between the target amplitude resolutions;
• automatically designate one of the first, second, or third generator circuits based on at least one of the timing resolution, the target amplitude resolutions, or the mathematical relationship, wherein the first generator circuit generates electrical pulses of a fixed shape, the second generator circuit generates electrical pulses controlled by amplitude parameters retrieved using dynamic memory access (DMA) operations during pulse generation, and the third generator circuit produces an electrical waveform with non-linear or sinusoidal amplitude variations;
• and
• transmit the target stimulation waveform and an activation instruction for the designated one of the first, second, or third generator circuits along the communication link, wherein the activation instruction activates the second generator circuit that includes a tangible and non-transitory memory that is configured to activate individual switches of an array of switches to generate the target stimulation waveform.
