This Section describes in brief about Diodes and Different Mosfets. section describes about Verilog i.e. Verilog is a hardware description language (HDL) that is used to describe digital systems and circuits in the form of code. It is widely used for design and verification of digital and mixed-signal systems, including both application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs). It supports a range of levels of abstraction, from structural to behavioral, and is used for both simulation-based design and synthesis-based design  System Verilog is an extension of Verilog that adds many features and capabilities for hardware design and verification. It is a hardware description and hardware verification language that is used to model, design, simulate, test, and implement electronic systems. ⦁ System Verilog supports object-oriented programming, constrained randomization, functional coverage, assertions, and other techniques that make it easier and faster to verify complex digital logic and circuits The operations that govern a neural network are, by nature, heavily parallel, whereas a CPU is mostly sequential – even for ones with multiple cores. Modern machine-learning architectures take advantage of the massively parallel processing power of the GPU to accelerate the training and computing process, but recent benchmarks show that as more parallelism is required, smaller scale, breadth-centric computing devices such as FPGAs can outperform GPUs; indeed, unlike GPUs that require external computing interfaces, full custom IC can be a efficient and independent alternative to the task of training the neural network and computing predictions. Front end design in VLSI is the process of creating the functional and logical model of a system using high-level design languages such as Verilog or VHDL. It involves defining the inputs and outputs, the data flow, and the overall architecture of the system. Front end design is typically done by architects and RTL designers, who use tools such as simulators, debuggers, and synthesizers to verify and optimize the design. Front end design is also known as RTL (register-transfer level) design
