CAD means computer aided design. CAD tools are used to design chips virtually on a computer. Programming languages like VHDL, Verilog, System C, Syatem Verilog are used for this purpose. The successful designs of these languages can be fabricated into chips.
C is a high level language that is compiled into machine language for specific system. The system implements some sort of state machine that can process the compiled machine language. In VHDL you have to design the statemachine itself. Furthermore VHDL is compiled into logic primitives that could be built by logic gates which itself could be realized with transistors. C is a programming language. VHDL is a hardware description language.
The main differences between the Class 90 and Class 91 were comfort whereby Class 91 was more comfortable.
the inner format.

They are very much the same, except VHDL syntax is derived from Ada while Verilog syntax is derived from C. ==================================== moreover, VHDL is a system level language whereas verilog is a gate level (circuit level) language. Hence, verilog is easy to learn than VHDL.
Verilog HDL / VHDL is a hardware description language used to implement a hardware on a computer virtually. It means that we can append all the attributes of a hardware to a computer program and verify as to how it works. But there may be differences in its behavior when it is actually implemented physically. For example, there may be an unexpected time delay. So, it is required to verify the design physically. Hence, we dump this Verilog / VHDL code into an FPGA / CPLD and verify the design physically. In other words, Verilog HDL / VHDL program is used to verify the design on a computer where as FPGA / CPLD implementation is used to verify the design on an IC.
Distillation is a method of separation for components of a liquid based upon the differences between boiling points.
Thermoplastic elastomers (TPE) and polyvinyl chloride (PVC) are two commonly used materials in various applications. The key differences between TPE and PVC lie in their flexibility, durability, and chemical resistance. TPE is more flexible and elastic, making it suitable for applications requiring stretchability and impact resistance. On the other hand, PVC is known for its rigidity and chemical resistance, making it ideal for applications where strength and durability are important. These differences impact their performance in various applications, with TPE being preferred for products like seals, gaskets, and soft-touch grips, while PVC is commonly used in construction, plumbing, and electrical applications.
HDL means hardware description language. These are the computer programming languages used to describe hardware. By doing so one can virtually realize hardware and test it. Verilog HDL is one of several hardware description languages available.
PVDF and PTFE are both fluoropolymer materials, but they have key differences. PVDF is more rigid and has better chemical resistance, making it suitable for applications requiring durability and resistance to harsh chemicals. PTFE, on the other hand, is more flexible and has a lower coefficient of friction, making it ideal for applications where low friction and non-stick properties are important, such as in cookware or medical devices. The differences in their properties impact their suitability for specific applications based on the specific requirements of the application.
conceptual; what should work. practical; what does work for a given situation at a given time
PTFE and polyethylene are both types of plastics, but they have key differences. PTFE is known for its high heat resistance and low friction, making it ideal for applications like non-stick coatings and in high-temperature environments. Polyethylene, on the other hand, is more flexible and has good chemical resistance, making it commonly used in packaging, pipes, and insulation. These differences in properties impact their applications and performance, with PTFE excelling in high-temperature and low-friction applications, while polyethylene is better suited for flexible and chemical-resistant uses.
Thermoplastic rubber (TPR) and thermoplastic elastomer (TPE) materials differ in their chemical composition and properties. TPR is a blend of rubber and plastic, offering good flexibility and durability, while TPE is a versatile material with a softer feel and better resistance to chemicals and weathering. These differences impact their performance in various applications, with TPR being more suitable for applications requiring toughness and abrasion resistance, while TPE is preferred for applications needing flexibility and resistance to harsh environments.
PNP means positive negative positive and viceversa. while both can be used on a circuit its polarity application must be followed.
Registers are very small but are extremely fast. RAM is much larger and smaller memory that applications use as a scratch space.
Lead and tungsten are both heavy metals commonly used in various applications. Lead has a lower density compared to tungsten, which means it is less dense and lighter. Tungsten, on the other hand, is denser and heavier. The differences in density between lead and tungsten affect their performance in different applications. Lead is often used for radiation shielding due to its ability to absorb and block radiation effectively. Tungsten, with its higher density, is used in applications where a higher level of density and weight is required, such as in aerospace components and in the production of high-performance alloys. In summary, the differences in density between lead and tungsten impact their performance in various applications, with lead being lighter and better for radiation shielding, while tungsten's higher density makes it suitable for applications requiring greater weight and density.
