ASICs requirements

Lubricating oils and similar products—Modem mechanical engineering requires lubricants capable of more and more sophisticated performances and hence needing a large number of additives suited to the most varied applications. Many of these requirements may be satisfied by properly designed Mannich bases, in particular when the drawback represented by their polar asic features, which make them water extractable, can be partially overcome by using the corresponding carbonated salts." ... 

The cap sensor includes a direct connected sensor and a protection cap mounted to the hub. The clip sensor can be mounted by its special geometry without a flange and screw. Present wheel-speed sensors are manufactured by overmolding the sensor elements (ASICs) directly with polyamide thermoplastic material, which fulfills the current needs. The requirements regarding temperature will increase for future car projects. This means a challenge for the development of materials and joining methods. 

Because the 02 signal is derived from the interaction of pumping and Nernst cells, this sensor requires a special electronic controller circuit. This ASIC (application-specific integrated circuit) includes the basic pumping current control, internal resistance measurement, and extended hardware diagnostics for the sensor. 

As discussed by Freshwater and Null, energy requirements of low-tem-erature distillation operations can often be reduced by retaining a single effect nd using a heat pump to pump heat from the condenser to the reboiler. Three asic schemes given by Null are shown in Fig. 17.10. In all three an expansion alve and a compressor are used to alter condensing and/or boiling temperatures... 

Electronic circuits must be protected from the harsh environment of the human body. The packaging of implantable electronics uses various materials, including polymers, metals, and ceramics. The encapsulation method depends somewhat on the electronic circuit technology. Older devices may still use discrete components in a classical form, such as leaded transistors and resistors. The newer designs, depending on the sophistication of the implanted device, may employ application-specific integrated circuits (ASICs) and thick film hybrid circuitry for their implementation. Such circuits place considerable requirements for hermeticity and protection on the implanted circuit packaging.

Achieving timing closure for large modern ASIC designs requires the use of physical synthesis—a series of performance-driven optimizations that simultaneously alter the layout, the netlist and electrical parameters of logic gates. 

Application specific integrated circuits (ASICs), also called custom ICs, are chips specially designed to (1) perform a function that cannot be done using standard components, (2) improve the performance of a circuit, or (3) reduce the volume, weight, and power requirement and increase the reliability... 

The main distinguishing feature of semicustom ASICs, compared to full custom ones, is that the basic circuit building blocks, whether analog or digital, are already designed and proven to work. These basic circuits typically reside in libraries within a CAD system. The users simply select from the library the components needed, place them on their circuits, and interconnect them. Circuit simulation is also done at a much higher level than SPICE, and the designer is, therefore, not required to be familiar with either semiconductor or device physics. 

This promotes the basic requirements for design and development of E/E/PE systems including hardware and software architecture, sensor, actuators, and PE including embedded software, application specific integrated circuit (ASIC), etc. Major issues related to this shall include but not be limited to the following ...

The thresholds of acidity for damage and pain may be different. A higher addity is likely needed for damage to the epithelial cells compared to the acidity required for stimulation of the pain fibers. This is probably because the epithelial cells have add-recovery mechanisms (such as Na /H or anion exchange) mostly absent in the pain fibers. Also, pain fibers contain add-sensitive ion channels (ASICs) that respond to environmental acidity. Depending on the location of the pain fibers and access thereto of H% individuals have different sensitivities to luminal acidity. The therapeutic aims of acid control may vary, being elevation of mean diurnal pH for healing of erosions or prevention of acidic excursions for symptom relief, or both. 

The logic synthesis process consists of two steps - translation and optimization. Translation involves transforming a HDL (RTL) description to gates, while optimization involves selecting the optimal combination of ASIC technology library cells to achieve the required functionality. 

The most popular DFT technique in ASIC design is the Scan Design Technique. Scan techniques involve replacing sequential elements in the design with equivalent scan cells. There exist different styles of scan cells. Based on the scan style selected the design is required to meet certain design rules. The most commonly used scan style is the multiplexed flip flop.
