An open source waveform generator based on Pulseq (open-source pulse sequence programming environment) for emerging matrix coils was developed, with the channel count of up to 64. The FPGA development board integrated with USB3.0 is used to store the waveform data and generate the waveform in real-time when external trigger signal is activated. The generator software was written in Python 2.7 with a queue structure.
