Capture one buffer of data from HDL IP core running on FPGA
Alternatively, instead of using the
function to perform the operation defined by the System object™, you can call the System object with arguments, as if it were a function.
y = step(obj,x) and
y = obj(x)
perform equivalent operations.
captures live signal data from a design running on an FPGA. The FPGA must contain an HDL IP
core generated from the FPGA Data
Capture Component Generator tool.
dataOut = step(
dataOut is a structure that
contains a field for each signal captured. Call the
setDataType object function to specify the data type of each captured signal.
If at least one signal is enabled as part of the trigger condition, the HDL IP core
waits for a match of the trigger condition and captures the data. If no signals are enabled
as part of the trigger condition, the HDL IP core captures and returns the buffered data
immediately. When you create the object, no trigger condition is set by default. Call the
setTriggerCombinationOperator object functions to configure a trigger
dataOut— Captured data
Captured data, returned as a structure containing a field for each signal captured by FPGA Data Capture. A vector of Sample depth values for each signal requested for data capture at generation time. The fields of the structure have the names you specified for the signals.
