setCaptureCondition(DC,name,enable,value)
configures a capture value comparison for the signal name.
DC is a customized data capture object. The
enable argument indicates whether this signal is part of the overall
capture condition.
This example uses a customized data capture object,
DC, that defines two signals for both trigger and data capture.
Signal A is 1 bit and signal B is 8 bits.
Enable capture condition logic.
DC.EnableCaptureCtrl = true;
To enable capture condition logic, you must select the Include capture
condition logic parameter while generating the data capture IP core using
the FPGA Data Capture Component Generator tool.
Set up a capture condition to capture data when the FPGA detects a high value on
signal A and a value 17 on signal B.
Name of the capture 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
Indication that the signal is part of the capture condition, specified as
true or false. To use this signal in the overall
capture condition, set this value to true. When you set this value to
false, the signal is not used for the overall capture
condition.
Value to compare the signal to as part of the capture condition, specified as one of
the following.
Decimal, binary, or hexadecimal value — For a multibit signal, specify
a value within the range of the data type associated with the signal. If you
specify a binary or hexadecimal value, you can use an X or
x to indicate signals for the function to ignore during the
value comparison.
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'.
'Low', 'High', 'Rising
edge', 'Falling edge', or 'Both
edges' — For a logical signal, specify a string that indicates
the level or edge to match. For more information, see Capture Conditions.
