Methods and systems for generating functional test patterns for manufacture test

A computer system for verifying functional test patterns for diagnostics, characterization and manufacture test comprising a memory having computer executable instructions;

• and a processor for executing the computer executable instructions, the computer executable instructions including:
• manually generating, by a system designer, a plurality of verification sequences selected from a verification sequence data to test system functional design, the plurality of verification sequences including a plurality of initial traces;
• adding custom information, via a trace processor module, to the plurality traces to generate a plurality of modified traces;
• executing the plurality of verification sequences received at a functional exerciser module of a functional test pattern generation (FTPG) system against a device to generate a plurality of traces;
• processing, via the trace processor module, the plurality of modified traces, the processing including parsing the plurality of modified traces captured;
• verifying data integrity of the plurality of traces captured, and summarizing statistics of the plurality of traces captured;
• generating, via an emulated pattern generator module of the FTPG system, a plurality of emulated test patterns having tester independent format streams of data compatible with a device test port, the generating based on output of the trace processor module;
• and
• verifying, via test pattern verification and debug module, plurality of emulated test patterns generated by the emulated pattern generator module.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor located on a computer system to cause the processor to perform a method of verifying functional test patterns for diagnostics, characterization and manufacture test, the method comprising:
