Resistor-capacitor transistor logic (RCTL), Emitter coupled logic (ECL) also known as Current-mode logic (CML), Transistor-transistor logic (TTL) and variants, P-type Metal Oxide Semiconductor logic (PMOS), N-type Metal Oxide Semiconductor logic (NMOS), Complementary Metal-Oxide Semiconductor logic (CMOS), Bipolar Complementary Metal-Oxide Semiconductor logic (BiCMOS). The push for reduced cost, more compact circuit boards, and added customer features has provided incentives for the inclusion of analog functions on primarily digital MOS integrated circuits (ICs) forming mixed-signal ICs. I write many articles, blogs to make people aware of any kind of education they are looking For. Most of the modifications are handled by EDA tools based on directives given by a designer. An Asic design engineer works within a team that are responsible for all aspects of design activities including architecture definition, design specification, design flow development, logic design and verifications. If the connection to silicon does not exist, charges may build up on the interconnect to the point at which rapid discharge does take place and permanent physical damage results to thin transistor gate oxide. Since this function is vital to the operation of a synchronous system, much attention has been given to the characteristics of these clock signals and the electrical networks used in their distribution.

Ques.1-What is an Application-Specific Integrated Circuit (ASIC)? The clock distribution network often takes a significant fraction of the power consumed by a chip. Clock gating is one of the power-saving techniques used on many synchronous circuits including the Pentium 4 processor. It then generates a netlist from each one and compares them. If you want to witty books, lots of novels, tale, jokes, and more fictions collections are also Besides their names, they might otherwise be identical. Phone : 080-51484444. Clock signals are typically loaded with the greatest fanout, travel over the greatest distances, and operate at the highest speeds of any signal, either control or data, within the entire synchronous system. Brodcomm Campus 3A, 5th Floor, RMZ Eco Space, Bellandur Village, Varthur Hobli, BANGALORE -- 560 037. Furthermore, significant power can be wasted in transitions within blocks, even when their output is not needed. Ans-These are the application specific integrated circuits in which a little change can be made during manufacturing so that they can be used for general applications of similar types although the masks for the diffused layers are already fully defined. Net-based netlists usually describe all the instances and their attributes, then describe each net, and say which port they are connected on each instance.

Platform ASICs are made from predefined platform slices, where each slice is a pre manufactured device, platform logic or entire system. During a latchup when one of the transistors is conducting, the other one begins conducting too. 1. draw a circuit to divide a clock by 2. Nets are the "wires" that connect things together in the circuit. Though it is expensive particularly if only a few pieces are required. ASIC INTERVIEW QUESTIONS-Ques.1-What is an Application-Specific Integrated Circuit (ASIC)? but error/split/retry is two cycles, why?

Functionality of .lib files will be taken from spice models and added as an attribute to the .lib file. 9- Which is the initially used technology for ASICs. Furthermore, these clock signals are particularly affected by technology scaling (see Moore's law), in that long global interconnect lines become significantly more resistive as line dimensions are decreased. Best IAS Coaching Institutes in Coimbatore. Application-specific integrated Circuit which is abbreviated as ASIC is the circuit which is designed to perform a specific and particular task. The Antenna ratio is defined as the ratio between the physical area of the conductors making up the antenna to the total gate oxide area to which the antenna is electrically connected. I guide people for the choice of thr Right Career Path as per their Interests. ERC steps can also involve checks for unconnected inputs or shorted outputs. In the case of a vacuum cleaner, these ports would be the three metal prongs in the plug. Netlists are connectivity information and provide nothing more than instances, nets, and perhaps some attributes. Each time a part is used in a netlist, this is called an "instance."

The parasitic structure is usually equivalent to a thyristor (or SCR), a PNPN structure which acts as a PNP and an NPN transistor stacked next to each other. The goal is to make single-chip radio frequency integrated circuits (RFICs) on silicon, where all the blocks are fabricated on the same chip. Usually, each instance will have a unique name, so that if you have two instances of vacuum cleaners, one might be "vac1" and the other "vac2". Article 2187 PDF Download.

You just have to know the real deal to survive a job interview. SPICE is perhaps the most famous of instance-based netlists. What is Synthesis? Others include Bipolar, BiCMOS and GaAs. One of the advantages of this integration is low power dissipation for portability due to a reduction in the number of package pins and associated bond wire capacitance. Ans.-CMOS is currently the dominant application specific integrated circuits fabrication technology due to its many advantages including cost, performance, density, and manufacturing / designer experience. ASIC's provide the path to creating miniature devices that can do a lot of diverse functions. All photolithographic layers of these ASICs are predefined and there is no room for change during manufacturing. If they express much more than this, they are usually considered to be a hardware description language such as Verilog, VHDL, or any one of several specific languages designed for input to simulators. This is a list of processing techniques that are employed numerous times in a modern electronic device and do not necessarily imply a specific order.
