Updated for:
Intel® Quartus® Prime Design Suite 19.4
IP Version 19.1.0

The Remote Update Intel® FPGA IP core implements a device reconfiguration using dedicated remote system upgrade circuitry available in supported devices. Remote system upgrade helps you deliver feature enhancements and bug fixes without recalling your product, reduces time-to-market, and extends product life. The Remote Update Intel® FPGA IP core commands the configuration circuitry to start a reconfiguration cycle.

The dedicated circuitry performs error detection during and after the configuration process. When the dedicated circuitry detects errors, the circuitry facilitates system recovery by reverting back to a safe, default factory configuration image and then provides error status information.

The following figures shows a functional diagram for a typical remote system upgrade process.

Note: Intel® recommends that you use the following Remote Update Intel® FPGA IP core input clock (fMAX) values:
  • 10 MHz—for Arria® II and Stratix® IV devices
  • 20 MHz—for other supported devices
