#CHIP DESIGN FLOW VERIFICATION#

Define a Clear Line Between SoC and IP:В During the development of the SoC level verification plan, you have to clearly define/identify the functionalities, which needs to be verified at the SoC level and at the sub-block or sub-IP or sub-cluster level.At this stage, a thorough understanding of SoC functionality and its architecture is required because misunderstanding of the specification can become the leading cause of bugs, and due to this, you may waste unnecessary time on issues which are not real RTL design problems. SoC Level/Top Level view (Feature Extractions)Дuring SoC design verification, you must view the design at the top level and extract its SoC level functionality/features during specification study phase for its verification.

Further, dividing the 4-bit adder into 1-bit adder or half adder. Here, the whole chip of 16 bit adder is divided into four modules of 4-bit adders. To understand this, letвЂ™s take an example of designing a 16-bit adder, as shown in the figure below. We can design the given task into the design flow process's domain (Behavioral, Structural, and Geometrical). This process is most suitable because the last evolution of design has become so simple that its manufacturing becomes easier. The design hierarchy involves the principle of 'Divide and Conquer.' It is nothing but dividing the task into smaller tasks until it reaches to its simplest level. Each of the domains can be divided into levels of abstraction, using concentric rings.ДЄt the top level (outer ring), we consider the architecture of the chip at the lower levels (inner rings), we successively refine the design into finer detailed implementation в€’Д¬reating a structural description from a behavioral one is achieved through the processes of high-level synthesis or logical synthesis.Д¬reating a physical description from a structural one is achieved through layout synthesis. The three domains of the Gajski-Kuhn Y-chart are on radial axes. The Gajski-Kuhn Y-chart is a model, which captures the considerations in designing semiconductor devices. A gatelevel netlist is a description of the circuit in terms of gates and connections between them, which are made in such a way that they meet the timing, power and area specifications.ДЇinally, a physical layout is made, which will be verified and then sent to fabrication. RTL description is then converted to a gate-level netlist using logic synthesis tools. From here onwards we need the help of EDA tools. This RTL description is simulated to test functionality. Specifications comes first, they describe abstractly, the functionality, interface, and the architecture of the digital IC circuit to be designed.Д«ehavioral description is then created to analyze the design in terms of functionality, performance, compliance to given standards, and other specifications. The various levels of design are numbered and the blocks show processes in the design flow. The VLSI IC circuits design flow is shown in the figure below. This trend is expected to grow rapidly, with very important implications on VLSI design and systems design. The current cutting-edge technologies such as high resolution and low bit-rate video and cellular communications provide the end-users a marvelous amount of applications, processing power and portability. With the advent of very large scale integration (VLSI) designs, the number of applications of integrated circuits (ICs) in high-performance computing, controls, telecommunications, image and video processing, and consumer electronics has been rising at a very fast pace. The electronics industry has achieved a phenomenal growth over the last few decades, mainly due to the rapid advances in large scale integration technologies and system design applications. VLSI lets IC designers add all of these into one chip. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. The microprocessor is a VLSI device.Д«efore the introduction of VLSI technology, most ICs had a limited set of functions they could perform. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip.
