SlimLinkComponentManager Class

class ska_mid_cbf_mcs.slim.slim_link_component_manager.SlimLinkComponentManager(*args: Any, **kwargs: Any)[source]

Bases: CbfComponentManager

A component manager for a SLIM link, which is made up of a Tx and Rx device from the ds-slim-tx-rx HPS device server.

property tx_device_name: str

The name of the HPS tx device that the link is associated with.

Returns:: the tx device name.
Return type:: str

property rx_device_name: str

The name of the HPS rx device that the link is associated with.

Returns:: the rx device name.
Return type:: str

property link_name: str

The name of the SLIM link.

Returns:: the link name.
Return type:: str

property tx_idle_ctrl_word: int

The idle control word set in the tx device. Initially generated in the HPS by hashing the tx device’s FQDN.

Returns:: the tx idle control word.
Raises:: Tango exception – if the tx device is not set.
Return type:: int

property rx_idle_ctrl_word: int

The last idle control word received in the datastream by the HPS rx device.

Returns:: the rx idle control word.
Raises:: Tango exception – if the rx device is not set.
Return type:: int

property bit_error_rate: float

The bit-error rate in 66b-word-errors per second.

Returns:: The bit error rate.
Raises:: Tango exception – if the rx device is not set.
Return type:: float

property simulation_mode: Get the simulation mode.

read_counters() → list[int][source]

An array holding the counter values from the HPS tx and rx devices in the order: [0] rx_word_count [1] rx_packet_count [2] rx_idle_word_count [3] rx_idle_error_count [4] rx_block_lost_count [5] rx_cdr_lost_count [6] tx_word_count [7] tx_packet_count [8] tx_idle_word_count

Returns:: The read_counters array.
Raises:: Tango exception – if link is not enabled.
Return type:: list[int]

start_communicating() → None[source]: Establish communication with the component, then start monitoring.

stop_communicating() → None[source]: Stop communication with the component.

connect_slim_tx_rx() → tuple[ska_tango_base.commands.ResultCode, str][source]

Link the HPS tx and rx devices by synchronizing their idle control words and disabling serial loopback. Begin monitoring the Tx and Rx.

Returns:: A tuple containing a return code and a string message indicating status. The message is for information purpose only.
Return type:: (ResultCode, str)

verify_connection() → tuple[ska_tango_base.commands.ResultCode, str][source]

Performs a health check on the SLIM link. No check is done if the link is not active; instead, the health state is set to UNKNOWN.

Returns:: A tuple containing a return code and a string message indicating status. The message is for information purpose only.
Return type:: (ResultCode, str)

disconnect_slim_tx_rx() → tuple[ska_tango_base.commands.ResultCode, str][source]

Stops controlling and monitoring the HPS tx and rx devices. The link becomes inactive. Serial loopback is re-established.

Returns:: A tuple containing a return code and a string message indicating status. The message is for information purpose only.
Return type:: (ResultCode, str)

clear_counters() → tuple[ska_tango_base.commands.ResultCode, str][source]

Clears the HPS tx and rx device’s read counters.

Returns:: A tuple containing a return code and a string message indicating status. The message is for information purpose only.
Return type:: (ResultCode, str)
