What is modularity in VLSI design?
Modularity allows that each block or module can be designed relatively independently from each other, since there is no ambiguity about the function and the signal interface of these blocks. All of the blocks can be combined with ease at the end of the design process, to form the large system.
What are CMOS design rules?
No Diffusion can cross demarcation line. Only poly and metal can cross demarcation line □ N-diffusion and p-diffusion are joined using a metal wire. Place all PMOS above and NMOS below demarcation line. Connect them using wires (metal).
What do you understand by modularity and locality?
The concept of modularity enables the parallelisation of the. design process. 3) Locality: The concept of locality also ensures that connections are mostly. between neighboring modules, avoiding long-distance connections as much as possible.
What are the two types of layout design rules?
Layout design rules: Contacts rules metal to p-active (p-diffusion) metal to n-active (n-diffusion)
What does the modularity mean?
Modularity is a system property which measures the degree to which densely connected compartments within a system can be decoupled into separate communities or clusters which interact more among themselves rather than other communities.
What is the need of scaling in VLSI?
Abstract. Device scaling is an important part of the very large scale integration (VLSI) design to boost up the success path of VLSI industry, which results in denser and faster integration of the devices.
What are the rules of design?
The principles of design are the rules a designer must follow to create an effective and attractive composition. The fundamental principles of design are: Emphasis, Balance and Alignment, Contrast, Repetition, Proportion, Movement and White Space.
What are the three design domains in VLSI?
A single hierarchy may not be sufficient to describe the VLSI design process. There are three design domains namely behavioral domain, structural domain and physical domain each with its own hierarchy.
What is CMOS layout?
Layout is “encoding” the physical realization of circuits. CMOS processing (manufacturing) is done in layers, so is layout. Photolithography (litho) is used to define regions for each layer. For each processing step, we need to transfer the mask onto the wafer (selectively coat/shield part of the wafer).
What is the role of modularity?
Modularity facilitates upgrades, adaptations, modifications and product assembly and disassembly, it also increases product variety, enables economies of scale and reduces production time.
