Use Comma Separated Values (.csv) files within stimulus profiles to stimulate, fault, and evaluate channels.

Format your CSV file.
Call the CSV file from a stimulus profile file as a real-time sequence or by reference from another real-time sequence file.

CSV files that you call as real-time sequences return a Boolean return value. This Boolean is false if the CSV file evaluates a channel that fails to meet any expected value defined within the CSV file. Otherwise, the Boolean returns true. CSV files that do not evaluate channels for pass/fail requirements always return true.
