Syntax

setTriggerCombinationOperator(hub,operator)
setTriggerCombinationOperator(hub,operator,Name=Value)

Description

setTriggerCombinationOperator(hub,operator) configures the logical operator that combines comparisons of individual signals into an overall trigger condition in trigger stage 1 for the first data capture IP. hub is a customized data capture object.

example

setTriggerCombinationOperator(hub,operator,Name=Value) configures the logical operator specifies options using one or more name-value arguments. For example, TriggerStageIndex=2 sets the trigger stage to 2.

Examples

This example uses a customized data capture hub object, hub, that connects with two data capture IPs. The first data capture IP is datacapture1 and the second data capture IP is datacapture2. Each IP defines two signals for both trigger and data capture. Signal A is 1 bit and signal B is 8 bits. The maximum number of trigger stages is set to 2.

Set number of trigger stages to 2 for both the IPs.

setNumberofTriggerStages(hub,2,DataCaptureName="datacapture1");
setNumberofTriggerStages(hub,2,DataCaptureName="datacapture2");

Set up a trigger condition to capture data when the FPGA detects a high value on signal A at the same time as signal B is equal to 17. Set this condition in trigger stage 2 for the datacapture1 IP.

setTriggerCondition(hub,'A',true,'High',TriggerStageIndex=2);
setTriggerCondition(hub,'B',true,uint8(17),TriggerStageIndex=2);

Combine comparisons of signals A and B into an overall trigger condition using an AND operator.

setTriggerCombinationOperator(DC,'AND',TriggerStageIndex=2);

Set up a trigger condition to capture data when the FPGA detects a high value on signal A at the same time as signal B is equal to 17. Set this condition in trigger stage 2 for the datacapture2 IP.

setTriggerCondition(hub,'A',true,'High', ...
TriggerStageIndex=2,DataCaptureName="datacapture2");
setTriggerCondition(hub,'B',true,uint8(17), ...
TriggerStageIndex=2,DataCaptureName="datacapture2");

Combine comparisons of signals A and B into an overall trigger condition using an AND operator.

setTriggerCombinationOperator(hub,'AND', ...
TriggerStageIndex=2,DataCaptureName="datacapture2");

Input Arguments

collapse all

Data capture hub object that interacts with each data capture IP, specified as a dataCaptureHub object.

Logical operator to combine comparisons of individual signals into a trigger condition, specified as 'AND' or 'OR'. The trigger condition comprises value comparisons of one or more signals. To combine value comparisons, you can use only one type of logical operator. For example, suppose three signals, A, B, and C, make up the trigger condition. The options are:

  • A == 10 AND B == 'Falling edge' AND C == 0
  • A == 10 OR B == 'Falling edge' OR C == 0

You cannot mix and match the combination operators. For details on trigger conditions, see Triggers.

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: setTriggerCombinationOperator(hub,'AND',DataCaptureName="datacapture1");

Trigger stage, specified as an integer from 1 to M, where M is set by the Max trigger stages parameter of the FPGA Data Capture Component Generator tool.

Name of the data capture IP, specified as a character vector or string scalar. The default value for this argument is "generatedIPName1", where generatedIPName1 is the name of the first data capture IP set by the Generated IP name parameter of the FPGA Data Capture Component Generator tool.
