Hitless Update

The hitless update feature avoids glitches on the I/Os during reconfiguration to keep the operation of downstream devices unaffected.

The MAX® 10 devices support the following hitless update modes:

  • JTAG mode—requires access to external JTAG pins
  • Non-JTAG mode—does not require access to external JTAG pins and accessible through the internal JTAG interface and FPGA fabric (e.g., I2C soft IP)

The hitless update feature freezes the I/Os during reconfiguration and reconfigures the new image with the pre-defined I/O states. You can perform the hitless update through a series of instructions using JTAG (internal or external) and the Dual Configuration Intel® FPGA IP for non-JTAG mode respectively. For more information refer to AN 904: MAX® 10 Hitless Update Implementation Guidelines and AN 963: MAX® 10 Hitless Update Implementation Guidelines Using Internal JTAG Interface.
