Read Online Vlsi Chip Design With The Hardware Description Language Verilog An Introduction Based On A Large Risc Processor Design To be precise about Very-large-scale integration is the procedure of creating a combined circuit by merging hundreds of thousands of transistors or devices into a single chip. In this way, verification is a form of testing, but verification tends to be trickier as you test something before the product actually exists, be it in software or hardware. The validation process involves activities like unit testing, integration testing, system testing and user acceptance testing. Instructor: Professor Jim Plusquellic . KEY DIFFERENCE Verification process includes checking of documents, design, code and program whereas Validation process includes testing and validation of the actual product. If any single transistor inside a chip becomes faulty, then the whole chip needs to be discarded. • Today, most testing circuits and testing vectors are generated automatically by CAD tools. While pre-silicon verification runs the test cases on the design on the simulator, post-silicon validation is executed on a few initial hardware prototypes of the design on the silicon chip in a real environment. 02 … Instructor: Virendra Singh .
