The table below lists the user-configurable PS PUF parameters for Zynq UltraScale+ MPSoC devices.
| Macro Name | Description |
|---|---|
| XSK_PUF_INFO_ON_UART | Default = FALSE TRUE displays syndrome data on UART com port. FALSE displays any data on UART com port. |
| XSK_PUF_PROGRAM_EFUSE | Default = FALSE TRUE programs the generated syndrome data, CHash, and Auxilary values, Black key. FALSE does not program data into eFUSE. |
| XSK_PUF_IF_CONTRACT_MANUFACTURER | Default = FALSE Enable this macro when application is hand over to contract manufacturer. TRUE allows only authenticated application. FALSE authentication is not mandatory. |
| XSK_PUF_REG_MODE | Default = XSK_PUF_MODE4KPUF registration is performed in 4K mode. For only understanding it is provided in this file, but user is not supposed to modify this. |
| XSK_PUF_READ_SECUREBITS | Default = FALSE TRUE reads status of the puf secure bits from eFUSE and displayed on UART. FALSE does not read secure bits. |
| XSK_PUF_PROGRAM_SECUREBITS | Default = FALSE TRUE programs PUF secure bits based on the user input provided at XSK_PUF_SYN_INVALID, XSK_PUF_SYN_WRLK, and XSK_PUF_REGISTER_DISABLE. FALSE does not program any PUF secure bits. |
| XSK_PUF_SYN_INVALID | Default = FALSE TRUE permanently invalidates the already programmed syndrome data.FALSE will not modify anything |
| XSK_PUF_SYN_WRLK | Default = FALSE TRUE will permanently disable programming syndrome data into eFUSE.FALSE will not modify anything. |
| XSK_PUF_REGISTER_DISABLE | Default = FALSE TRUE permanently does not allow PUF syndrome data registration.FALSE will not modify anything. |
| XSK_PUF_RESERVED | Default = FALSE TRUE programs this reserved eFUSE bit. FALSE will not modify anything. |
| XSK_PUF_AES_KEY | Default = 0000000000000000000000000000000000000000000000000000000000000000
The
value mentioned in this is converted to hex buffer and encrypts this with PUF helper
data and generates a black key and written into the Zynq UltraScale+ MPSoC PS eFUSE
array when XSK_PUF_PROGRAM_EFUSE macro is TRUE. Provide this value in the string
format with 8 characters long. Valid characters are 0-9,a-f,A-F. Any other character
is considered as invalid string and does not AES key. Note:
Provide red key in this macro and application calculates the black key and programs
into eFUSE if XSK_PUF_PROGRAM_EFUSE macro is TRUE. To avoid programming eFUSE
results can be displayed on UART com port by making XSK_PUF_INFO_ON_UART to
TRUE.

| XSK_PUF_BLACK_KEY_IV | Default = 000000000000000000000000 The value mentioned here is converted to hex buffer. This is Initialization vector(IV) which is used to generated black key with provided AES key and generated PUF key. Provide this value in the string format with 24 characters long. Valid characters are 0-9,a-f,A-F. Any other character is considered as invalid string. |
