2.3.10. Configuring an External Host for Intel® Arria® 10 or Intel® Cyclone® 10 GX Designs

When using external host configuration, the external host initiates partial reconfiguration, and monitors the PR status using the external PR dedicated pins during user mode. In this mode, the external host must respond appropriately to the handshake signals for successful partial reconfiguration. The external host writes the partial bitstream data from external memory into the Intel® Arria® 10 or Intel® Cyclone® 10 GX device. Co-ordinate system-level partial reconfiguration by ensuring that you prepare the correct PR region for partial reconfiguration. After reconfiguration, return the PR region into operating state.

To use an external host for your design:

  1. Click Assignments > Device > Device & Pin Options.
  2. Select the Enable PR Pins option in the Device & Pin Options dialog box. This option automatically creates the special partial reconfiguration pins, and defines the pins in the device pin-out. This option also automatically connects the pins to PR control block internal path.
    Note: If you do not select this option, you must use an internal or HPS host. You do not need to define pins in your design top-level entity.
  3. Connect these top-level pins to the specific ports in the PR control block.

The following table lists the PR pins that automatically constrain when you turn on Enable PR Pins, and the specific PR control block port connection to the pin:

Table 31.  Partial Reconfiguration Dedicated Pins
Pin Name Type PR Control Block Port Name Description
PR_REQUEST Input prrequest Logic high on this pin indicates that the PR host is requesting partial reconfiguration.
PR_READY Output ready Logic high on this pin indicates that the PR control block is ready to begin partial reconfiguration.
PR_DONE Output done Logic high on this pin indicates that the partial reconfiguration is complete.
PR_ERROR Output error Logic high on this pin indicates an error in the device during partial reconfiguration.
DATA[31:0] Input data These pins provide connectivity for PR_DATA to transfer the PR bitstream to the PR controller.
DCLK Input clk Receives synchronous PR_DATA.
Note:
  1. PR_DATA can be 8, 16, or 32-bits in width.
  2. Ensure that you connect the corectl port of the PR control block to 0.
