Functional Verification Requirements

Solution focus

Listing the functions to check and their decision conditions creates a common reference for later verification requirements.

Engineering basis

IPC-2581 covers data exchange for manufacturing, assembly and inspection, and the IPC checklist places netlist, BOM and test-related information in one package. Functional verification should therefore begin with executable inputs, expected results and a recording method.

Design focus

• Break checks into repeatable functional items
• State input condition, expected output and decision method for each item
• Identify required interfaces, test points and external equipment early

Recommended information

• Functions that need to be checked
• Input conditions and expected results
• Recording method and criteria still to confirm

Handoff and verification

• Functional test checklist
• Input/output and decision-condition table
• Test connection, record format and open thresholds

Next collaboration step

After the information for functional verification requirements is confirmed, align the functional, interface, material, assembly and revision information before the next solution discussion.
