Pin names

It is important to note that pin names do not specify net names or connectivity. In other words, commonly named pins are not automatically connected, and the net to which they are connected is not named the same as the pin names. Thus, as shown above, none of the blocks are connected. To connect the blocks, we need to wire them together. The schematic shown below shows the blocks wired together. Note that some wires are labeled with the text Vcc and Vee. This was done using net aliases as described in section l.H. Note also the wire fragments used for Vee. These wires are all given the same net name (Vee) and thus are connected. This is a shorthand method for connecting components without drawing wires all over your schematic ... 

Next, we need to modify the graphic symbol. You can move the pins, but do not change them or rename them. You can hide the pin names (Vp, Vm, or Vo) if you wish, but you cannot change their names because they correspond to the calling nodes used in the subcircuit netlist. You can delete the box and then add any graphics you wish using the place menu. My modified symbol is shown below ... 

The symbol is now useable. However, I do not like the location of the pin names so I will turn off their display. This is done using the same method we used to hide the pin numbers. (Select Options and then Part Properties from the menu and change property Pin Names Visible to False.)The result is shown below ... 

The output pin is obvious to a user of this part but the input pins are not. I will add + and - symbols to the symbol. I know which is which because a few moments ago, the pin names where displayed on the symbol. You can place text by selecting Place and then Text from the menus ... 

I want the pin names to be displayed, but I do not want to display the pin numbers. To change the display, select Options and then Part Properties ... 

FIGURE 18.7 Example of a netlist (a) this part represents a physical netlist with X and y coordinates (the first line translates as Kn U5 of component IC52 is connected to net LDIN 47 and is at location [11.0078, 3.0997] (b) this part represents the same netlist but at schematic stage with only component and pin names the electric signal identified as LDIN 47 connects IC52 pin V5 to ICIO pin J2 through two vias. 

The technology and symbol libraries must exactly match in case for the cell names and their pin names. In other words, if the pin names of the IVA cell in the technology library do not match the pin names of the cell IVA in the symbol library, the tool will not be able to use the IVA symbol. In such a scenario, the tool uses symbols from the synopsys default generic library. The comparejib command in DC, is a fast check mechanism to determine any differences between the symbol library and the technology library that might exist. 

If DA still shows boxes instead of symbols, it is likely that the symbol library and the technology library do not match in case for the pin names or cell names. Execute the comparejib command to verify the same as shown in sectionl.2.3. 

STRUCTURAL employs only Nand components. The logic synthesized circuit is shown in Figure 4.24. Each block represents a single instantiated component, as indicated by its label. The signals 10 to 15 are declared in the architecture for internal routing between components. The pin names allocated to each top-level block correspond to the ports declared in the components entities. The external input and output signals are as declared in the Port statement of the entity MUX4TOI.

This inward force has a real agent, namely, a tension of the cord, which is applied to the body. The same cord acts on the pin with a force, which has the same magnitude as that of the centripetal one but opposite direction. This force has the same physical origin, (deformation of cord) and it is called the centrifugal force. The term centrifugal means literally fleeing a center . Centripetal and centrifugal forces always form a pair of action and reaction and they are applied to different parts of the system. In our case these parts are a small body and a pin. 

Another material based on the crown ether extractant 4,4 (5 )-bis(t-butyl-cyclohexano)-18 crown-6, marketed under the name Sr-Spec, is useful for separations involving divalent cations including Pb, Ba, and Ra (Horwitz et al. 1991). For Ra analysis by TIMS, Ra-Ba separations are required because the presence of Ba drastically decreases the ionization efficiency of fg Ra samples from 10% to <1%. This material has been widely used for separations of Ra from Ba (e.g., Chabaux et al. 1994 Lundstrom et al. 1998 Rihs et al. 2000 Joannon and Pin 2001 Pietruszka et al. 2002) and is a complement or alternative to cation exchange separations for EDTA complexes of these elements (Volpe et al. 1991 Cohen and O Nions 1991). Sr-Spec material would also be useful for °Pb analysis, since Pb has a greater distribution coefficient than Sr with this extractant. 

For specially chosen pressure P- there is a unique solution of the Einstein equations in Eqs. (6)-(9), namely T = 0. In this case Eqs. (6)-(8) can be solved separately with = 0 and then the last Eq. (9) gives P5. Although these solutions do not differ formally from the 4 dimensional neutron star solution (except for P5), but the extra dimension will have its influence on e(n) and Pin) [7],... 

As the name suggests, indeterminate errors cannot be pin-pointed to any specific well-defined reasons. They are usually manifested due to the minute variations which take place inadvertently in several successive measurements performed by the same analyst, using utmost care, under almost identical experimental parameters. These errors are mostly random in nature and ultimately give rise to high as well as low results with equal probability. They can neither be corrected nor eliminated, and therefore, form the ultimate limitation on the specific measurements. It has been observed that by performing repeated measurement of the same variable, the subsequent statistical treatment of the results would have a positive impact of reducing their importance to a considerable extent. 

Williams and coworkers preliminarily reported that CO oxidation on Pt/Al203 is faster in the presence of water solvent than in the presence of ethanol [141]. We then studied CO oxidation on platinum surface in the presence of different solvents, and identified obvious solvent effects, namely, CO oxidation takes place the most easily with water solvent, the least easily with carbon tetrachloride solvent, and follows the overall trend of water > ethanol > methanol > cyclohexane > benzene carbon tetrachloride [67]. We subsequently took advantage of the solvent effect to design a diagnosing tool to pin down low-coverage CO at the liquid-solid interface, by flushing the liquid-solid interface with water and carbon tetrachloride individually [67].

The most important applications of nickel metal involve its use in numerous alloys. Such alloys are used to construct various equipment, reaction vessels, plumbing parts, missile, and aerospace components. Such nickel-based alloys include Monel, Inconel, HasteUoy, Nichrome, Duranickel, Udinet, Incoloy and many other alloys under various other trade names. The metal itself has some major uses. Nickel anodes are used for nickel plating of many base metals to enhance their resistance to corrosion. Nickel-plated metals are used in various equipment, machine parts, printing plates, and many household items such as scissors, keys, clips, pins, and decorative pieces. Nickel powder is used as porous electrodes in storage batteries and fuel cells.
