The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from OVM (Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) for the e verification language developed by Verisity Design in 2001.
In the design verification role, SystemVerilog is widely used in the chip-design industry. The three largest EDA vendors (Cadence Design Systems, Mentor Graphics, Synopsys) have incorporated SystemVerilog into their mixed-language HDL simulators.
The Open Verification Methodology (OVM) is a documented methodology with a supporting building-block library for the verification of semiconductor chip designs. The initial version, OVM 1.0, was released in January, 2008, [1] and regular updates have expanded its functionality.
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
Verilog was created by Prabhu Goel, Phil Moorby and Chi-Lai Huang between late 1983 and early 1984. [3] Chi-Lai Huang had earlier worked on a hardware description LALSD, a language developed by Professor S.Y.H. Su, for his PhD work. [4]
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]
Functional verification is very difficult because of the sheer volume of possible test-cases that exist in even a simple design. Frequently there are more than 10^80 possible tests to comprehensively verify a design – a number that is impossible to achieve in a lifetime.
Physical verification is a process whereby an integrated circuit layout (IC layout) design is verified via EDA software tools to ensure correct electrical and logical functionality and manufacturability.
