The NOPAL Language Specification and User Manual

As the maintenance cost continues to soar, the application of computer program for testing components becomes necessary. This report describes the specification and usage of automatic computer program generation for Automatic Test Equipment (ATE). The function of the automatic generated program is to validate UUT (Unit Under Test) design test point availability, and packaging. The system is referred to as NOPAL, an acronym for Non-procedural Operational Performance Analysis Language. Non-proceduralness is the essential feature of the NOPAL language; in that test modules are specified modularly, and independently, one upon another. Therefore, the additions and/or modifications of tests can be incorporated easily and they are automatically attached in the proper places in the program. The report consists of five sections. Introduction, EBNF Specification, Test Module Specification, UUT Specification, and ATE Specification. For each NOPAL statement, its EBNF definition, syntax diagram and examples are provided.
