Functional validation of a packet management unit

A validation system for validating functions of a packet management unit (PMU) operationally coupled through a system interface to a stream processing unit of a packet processor, the validation system comprising:

• a model configured to emulate functions of the PMU, the system interface, and the stream processing unit;
• and
• evaluation software for checking results;
• wherein the model is further configured to:
• receive an input packet stream;
• process the input packet stream;
• and
• generate output activity;
• and
• wherein the evaluation software is configured to compare the output activity to criteria of a test code resulting in an indication of pass or failure.

A validation system comprising:

• a model configured to:
• emulate a packet processor including a packet management unit (PMU) coupled through a system interface to a stream processing unit;
• and
• generate an output packet stream in response to receiving an input packet stream;
• and
• a checker coupled to the model, wherein said checker is configured to:
• receive a test code including criteria for evaluating an output packet stream;
• receive a test output packet stream generated by the model;
• and
• compare the test output packet stream to the criteria to determine success or failure of a test of the model.

A method for validating functions of a packet-management unit (PMU) operationally coupled through a system interface to a stream processing unit of a packet processor, the method comprising:

• emulating functions of the PMU, the system interface, and the stream processing unit in a model;
• inputting a packet stream into the model;
• outputting from the model an output activity representing the packet stream after processing;
• and
• examining the output activity according to input parameters and criteria of a test code to determine if a concluded test has passed or failed.
