tf = isLocked(DC) returns the locked status, of the specified hdlverifier.FPGADataReader System object™.

isLocked returns a logical value that indicates whether input attributes and nontunable properties for the object are locked. The object performs an internal initialization the first time that you call the object. This initialization locks nontunable properties and input specifications, such as the dimensions, complexity, and data type of the input data. After locking, isLocked returns a true value.

Input Arguments

Data capture System object, specified as an hdlverifier.FPGADataReader System object. You can create this type of System object by using the FPGA Data Capture Component Generator app.

Output Arguments

collapse all

True or false result indicating the locked status of the input System object DC, returned as a 1 or 0 of data type logical. A 1 indicates the System object is locked.
