Port I/O Size (Bit) Description
clkin

Input

1

Feeds clock signal to the chip ID block. The maximum supported frequencies are as follows:

  • For Intel® Arria® 10 and Intel® Cyclone® 10 GX: 30 MHz.
  • For Intel® MAX® 10, Stratix® V, Arria® V and Cyclone® V: 100 MHz.
reset

Input

1

Synchronous reset that resets the IP core.

To reset the IP core, assert the reset signal high for at least 10 clkin cycles1.

The chip_id [63:0]output port holds the value of the unique chip ID until you reconfigure the device or reset the IP core.

data_valid

Output

1

Indicates that the unique chip ID is ready for retrieval. If the signal is low, the IP core is in initial state or in progress to load data from a fuse ID. After the IP core asserts the signal, the data is ready for retrieval at the chip_id[63..0] output port.

chip_id

Output

64

Indicates the unique chip ID according to its respective fuse ID location. The data is only valid after the IP core asserts the data_valid signal.

The value at power-up resets to 0.

1 The Intel® MAX® 10 reset requires only one clock cycle.
