Pad cell

Arkhe s PLA fibres are used to produce a range of novelty goods including calendar cases, bags, clips, name card holders, mouse pads, cell phone straps, diary covers and stationery. They have been certified as fully biodegradable under the Japanese GreenPla system. 

Adding pads to your design is an essential part of the design process. One option is to instantiate pads after the core of the design has been implemented and simulated. Figure 5.4 shows an ASIC core with the pad cells. DC provides a means for automatic pad insertion. However, this is entirely dependent on Ae ASIC vendor library having appropriately modeled pad cells. A pad cell in the Synopsys library is one which has... 

If DC issues a message that it is unable to find the library libA.db, execute the list -libraries command at the dc shell prompt. This command should list the UNIX file name and the actual name of the library. Having determined the pad cells available in the library, the next step is to find the pin on the pad cell (say padA) that has the is pad attribute. This can be done using the following command ... 

This is a veiy common scenario. Most often, one might need to swap a buffer, a particular cell or maybe a pad cell. In each of these cases, the changejink command is very useful. If you are familiar with the capabilities of the cells in the technology library, then changejink command can be used very effectively to address issues such as, Tf DC used the X cell in the Z path instead of the Y cell, then it should be able to meet the timing requirements. ... 

How can I check if my technology library supports automatic pad synthesis. What commands can be used to list all the pad cells in the library. 

The pad cell attribute is used to identify a cell as an I/O pad cell. DC filters pad cells out of the normal core optimization and treats them differently during technology translation. Also, each cell that is identified as an I/O pad must have a pin that represents the pad. Such pins are identified by the is pad attribute. Additionally the direction attribute indicates whether the cell is an input, output, or bidirectional pad. The following command can be used to find all the I/O pad cells in the lsi 1 Ok library ... 

If this command returns a list of pad cells, your library supports automatic pad synthesis and the insert pads command can be used to insert pads in your design. 

Perform JTAG insertion with the required options. Use the -no pads option if the ASIC vendor library does not support automatic pad synthesis. In general, to have complete control over the pad cells, it is recommended that you instantiate pad cells in your design. 

In order to control and specify the characteristics of the desired pad cell, use the set pad type command. DC inserts pads for all ports in the design which have the portJs pad attribute. This attribute can be applied using the set portJs pad command.

As a vessel is loaded, it moves downward because of deflection of the load cells and support stmcture. Pipes rigidly attached to a vessel restrict its free movement and assume some portion of the load that cannot be measured by the load cells. This is very detrimental to scale accuracy. Deflection of the load cell is unavoidable deflection of the vessel support stmcture should be minimized. Anything which increases vessel deflection, eg, mbber pads used for shock protection, must be avoided. The total number of pipes should be minimized and be of the smallest diameter, thinnest wall possible. Pipe mns to weigh vessels must be horizontal and the first pipe support should be as far as possible from the vessel. Alternatively, a section of mbber hose or flexible bellows should be used to make the final connection to the vessel. The scale should be caUbrated using weights, not by means of an electrical simulation method, which cannot account for the effects of the piping or test the correct functioning of the scale. 

Air-Filter Types Air filters may be broadly divided into two classes (1) panel, or unit, filters and (2) automatic, or continuous, filters. Panel filters are constructed in units of convenient size (commonly 20- by 20-in or 24- by 24-in face area) to facilitate installation, maintenance, and cleaning. Each unit consists of a cleanable or replaceable cell or filter pad in a substantial frame that may be bolted to the frames of similar units to form an airtight partition between the source of the dusty air and the destination of the cleaned air.

Co concentration was determined by spectrophotometer (Varian Cary 500) at 692 nm wave length, with the sample diluted with a 9 mol/L concentrated HCl solution. NO content in gas phase was obtained by an on-line Fourier transform infrared spectrometer (Nicolet E.S.P. 460 FT-IR) equipped with a gas cell and a quantitative package, Quant Pad. 

A number of workers have described methods for the determination of mercury in which the mercury is first reduced to the element or collected as the sulfide on a cadmium sulfide pad. It is then volatilized into a chamber for measurement. These techniques are extremely sensitive. Thillez108) recently described a procedure for urinary mercury in which the mercury is collected on platinum and then volatilized into an air stream. Rathje109) treated 2 ml of urine with 5 ml of nitric acid for 3 min, diluted to 50 ml, and added stannuous chloride to reduce the mercury to the element. A drop of Antifoam 60 was added and nitrogen was blown through the solution to carry the mercury vapor into a quartz end cell where it is measured. Six nanograms of mercury can be detected. Willis 93) employed more conventional methods to determine 0.04 ppm of mercury in urine by extracting it with APDC into methyl-n-amyl ketone. Berman n°) extracted mercury with APDC into MIBK to determine 0.01 ppm. 

Celite or hyflo super cell (20 g) was added to the suspension which was then filtered through a pad of hyflo in a wide-sinter funnel the pad was washed with water (100 mL). The filtrate was saturated with sodium chloride and then extracted with ethyl acetate (5 x 500 mL). The combined extracts were dried over magnesium sulfate, filtered and the solvent was removed under reduced pressure to afford a pale viscous oil.
