Fast boot systems and methods for programmable logic devices

A method comprising:

• receiving configuration data associated with a programmable logic device (PLD), wherein the PLD comprises an array of configuration memory cells comprising a plurality of logic block memory cells associated with a logic fabric of the PLD and a plurality of input/output (I/O) block memory cells associated with an I/O fabric of the PLD;
• programming a subset of the I/O block memory cells with a first portion of the configuration data;
• providing a first wakeup signal to wake up functionality associated with a portion of the I/O fabric associated with the subset of the I/O block memory cells;
• in response to the first wakeup signal, providing, by the portion of the I/O fabric, a first functionality;
• programming remaining configuration memory cells of the array with a second portion of the configuration data, wherein the remaining configuration memory cells comprise at least a subset of the logic block memory cells;
• providing a second wakeup signal to wake up functionality associated with at least a portion of the logic fabric associated with the subset of the logic block memory cells;
• and
• in response to the second wakeup signal, transitioning the portion of the I/O fabric and the portion of the logic fabric into a system operation mode, wherein:
• within a predetermined amount of time after the transitioning into the system operation mode, maintaining, by the portion of the I/O fabric, the first functionality;
• and
• after the predetermined amount of time, providing, by the portion of the I/O fabric, a second functionality.
