        FPGA and SoC hardware design overview and basics for a Xilinx Zynq-based System-on-Module (SoM). What circuitry is required and what to pay attention to (decoupling, configuration, voltages, sequencing, pull-ups/pull-downs, etc.) when designing more advanced hardware. Example design for Xilinx Zynq XC7Z007S System-on-Chip (SoC) in a CSG225 BGa package. Including multi-voltage buck converters, DDR termination regulators, DDR3L memory, QSPI and EMMC memory, and more!
