setTriggerCondition

Configure each signal value comparison

Syntax

setTriggerCondition(DC,name,enable,value)

setTriggerCondition(DC,name,enable,value,N)

Description

setTriggerCondition(DC,name,enable,value) configures a trigger value comparison for signal name in trigger stage 1. DC is a customized data capture object. The enable argument indicates whether this signal is part of the overall trigger condition.

setTriggerCondition(DC,name,enable,value,N) configures a trigger value comparison for signal name in a trigger stage specified by N. DC is a customized data capture object. The enable argument indicates whether this signal is part of the overall trigger condition.

Input Arguments

DC — Customized data capture object

hdlverifier.FPGADataReader System object™

Customized data capture object, specified as an hdlverifier.FPGADataReader System object.

name — Name of trigger component signal

character vector

Name of trigger component signal, specified as a character vector.

This name must match one of the signal names configured on creation of the input System object DC. The signal must be configured as a possible trigger signal.

Data Types: char

enable — Indication that signal is part of trigger condition

true or 1 | false or 0

Indication that the signal is part of the trigger condition, specified as a numeric or logical 1 (true) or 0 (false). To use this signal in the overall trigger condition, set this value to 1 (true). When you set this value to 0 (false), the signal is not used for the overall trigger condition.

value — Value to compare this signal to as part of the trigger condition

decimal | binary | hexadecimal | 'Low' | 'High' | 'Rising edge' | 'Falling edge' | 'Both edges'

The trigger condition comprises value comparisons of one or more signals. This input specifies the value to match for each signal.

For a multibit signal, specify a decimal, binary, or a hexadecimal value within the range of the data type associated with the signal. While providing hexadecimal or binary values, you can provide values with a combination of X or x (don't care value) to enable bit masking. That means, while comparing the values, the trigger condition ignores the place values with X or x and provides the output.

To separate a group of bits for better readability, you can use _ between bits. For example, you can represent a 32-bit binary value as '0b1010_XXXX_1011_XXXX_1110_XXXX_1111XXXX' and a 32-bit hexadecimal value as '0xAB_CDEXFX'.

For logical signals, specify a string that indicates the level or edge to match. For more information, see Triggers.

N — Trigger stage

integer from 1 to M

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. Use N to set the trigger condition in Nth trigger stage. If you do not specify N, by default, the function sets the trigger condition in trigger stage 1.
