ptp module

PTP (Precision Time Protocol) Peripheral ICL (Instrument Control Layer). Abstracts the FPGA registers into a more user-friendly interface, including a wrapper for configuration registers inside the IP core.

class ptp.Ptp(*args: Any, **kwargs: Any)

Bases: FpgaPeripheral

ICL for Base PTP Peripheral Configuration

command(cmd: PtpCommand) → None

Execute a PTP command

property mac_address: ska_low_cbf_fpga.IclField.<class 'str'>

Get MAC address

startup(mac_address: int = 66051, domain: int = 1) → None

Start PTP

Parameters:

• mac_address (int) – MAC address, only the low 3 bytes are used.

• domain (int) – PTP domain

property user_mac_address: ska_low_cbf_fpga.IclField.<class 'int'>

Get the user-configurable portion of the MAC address (lower 3 bytes)
