Description

This block provides an interface to help the user generate the configuration data of the AOut Mapping & Adjustments CPU block. It is used to specify the origin and scaling of the signals driving each analog output channel controlled by its parent driver block.


Mask Parameters

General

AOMR Version: This parameter allows to choose between the two available versions of the AOMR block. The V1 allows to configure 1 or 2 lanes: lane 1 is parallel and lane 2 is serial. The V2 version allows to configure from 1 to 8 serial lanes.

Number of lanes: This parameter allows to choose how many lanes to configure. If 0 is selected, only CPU inputs are available.

Open Mapping Table: This button opens the Mapping Table view where the signals assignation, gain, offset, min and max can be tuned.

Lanes

The number of lanes sections displayed depends on the number of lanes parameter selected in the General box. The CPU inputs section is always available even if 0 lanes are selected.

A lane section contains :

Source: Dropdown to choose between Custom List and Unassigned. This choice enables the Signals List.

Signals List: Allows to enter the signals list going to the lane. This list has to be exhaustive and the order of the names must match the actual order of the signals in the wire

AOMR Mapping Table

Signal: This parameter sets the signal to be sent to the corresponding Analog Out.

Gain: This parameter sets the gain to be applied on the selected signal.

Offset: This parameter sets the offset to be applied on the selected signal.

Min (Volts): This parameter sets the AO channel output minimum voltage.

Max (Volts): This parameter sets the AO channel output maximum voltage.

The formula applied to the output signal is: Output AO voltage = saturate(signal*gain+offset,min,max)


Inputs

This block has no input.


Outputs

To_Aout: This output is used to connect to the Aout_Mapping&Adjustments block. It contains all the parameters (mapping, gains, offsets, maximums and minimums) of every signals.


Characteristics and limitations

The user must ensure that the gains, offsets and saturation threshold are consistent and fit any external hardware limitations. As an example, if the bottom saturation threshold is higher than the top saturation threshold, and both thresholds are trespassed simultaneously, a constant zero will be sent as the analog output signal.
