電子書-RTL Design Style Guide for Verilog HDL540頁(yè)A FF having a fixed input value is generated from the description in the upper portion of
Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input,
and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at
the power supply, since the typical value ’1’ is output following the rise of the START
signal.
When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementing a scan design and converting to a scan FF, the scan
may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower
part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that
the clock signal is input to the clock pin of the FF.
Other than the sample shown in Example 2-21, there are situations where for certain
control signals, those that had been switched due to the conditions of an external input
will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a
fixed value is input from an upper level, the input value of the FF may also end up being
fixed as the result of optimization with logic synthesis tools. In a situation like this, while
perhaps difficult to completely eliminate, the problem should be avoided as much as Possible.
如果在調(diào)諧器或電視機(jī)附近使用本機(jī)或任何其他使用微處理器的電子設(shè)備，則可能會(huì)產(chǎn)生圖像的噪聲或干擾。如果發(fā)生這種情況，請(qǐng)采取以下步驟將本機(jī)安裝在盡可能遠(yuǎn)離調(diào)諧器或T的地方。遠(yuǎn)離調(diào)諧器或T，遠(yuǎn)離本機(jī)的電源線和輸入/輸出連接電纜。尤其在使用室內(nèi)天線或300歐姆饋線。我們建議使用室外天線和75 Q / ohm同軸電纜Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV If this happens, take the following stepsInstall this unit as far away as Possible from the tuner or T Run the antenna wires from the tuner or T away from this unit ' s power supply cord and input/output connection cables. Noise or disturbance tends to occur particularly when using indoor antennas or300 ohm feeder wires. We recommend using outdoor antennas and 75 Q/ohm coaxial cables
Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder resolution, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what happens of fast systems or, vice versa, speed up slow process.Because National Instruments is a unique company in the fact the we provide a fullhardware solution couple with a full development platform, we can use this tools in very particular ways For example, it is Possible to combine the LabVIEW Control Design and Simulation Module along with the FPGA module to quickly prototype a controller. One of the main benefits of this approach is that there is no need to compile the FPGA code, which allows for a quick algorithm design turnaround and debugging.
