3004202330-1-Wang Huiquan-1. How to weld the smd ic on the chip adapter board? Prepare tools for welding the integrated circuit of the table, such as a good soldering iron (the finer the head, the better) and solder paste. For fine pin spacing, first apply a layer of solder paste on the clean pad, and then use a clean constant temperature soldering iron to thin a layer of Solder Pad (according to observation, some transfer board has been painted for t

and cannot be changed. Block 0, Block 1, and block 2 of other sectors are data blocks used to store user data. Block 3 is the control block of each sector, it is used to store Password A, access control condition settings, and password B. The structure of each region's control block is the same. The size shown in 1 is 16: zone * 4*16 bytes = 1024 bytes. 1. Shows the storage structure: Block 0 IC card manufact

emerged, just meet the Cloud,the DevOps era of the new network needs, the two-tier network is not either, but must wing, together to support new applications and users. North-South Network (core network) is the responsibility of carrying traffic, reliable, safe is the key. Things to the network (application Network) responsible for production flow, need and application of close cooperation, elasticity, security is the key. By constructing dc2t network Architecture, we can help enterprises to me

. But these so-called "Internet +" enterprises to carry out a large area, a large number of human flesh promotion, in fact, has violated the "Internet +" the original intention. This kind of enterprise only wears "the Internet +" The cloak, does the qishidaoming dream, finally becomes "the Internet-" The model and dies, such example is a plethora of examples ...Any business that does not aim to make money is bullying, but the business cannot be born for money alone. No line of people scary, no b

state of the inductor, switch on-time (current rise) of the number of volts seconds must be switched off (current drop segment) when the number of volts seconds is equal, although the two symbols opposite.Formula:Δvon Ton =δvoff ToffSo we can exit the buck circuit:(VIN-VO) *dt=vo* (1-d) Tvo=vin *DD is the duty ratio, which is expressed here is the inductance charge voltage (Vin-vo) and the product of the charge time equals the voltage of the inductive discharge (VoMultiplied by the discharge ti

, in fact, it does not save the memory. I recommend it because of the speed of the operation. In this example, we can see the difference between the unsigned operation and the signed operation on the digital path, that is to say, if only Int Is Used in C/C ++, signed operation will be run in the hardware, and unsigned int will run unsigned operation, which is fast, therefore, the estimation is based on the speed consideration using the unsigned Int. ReferenceExample of Digital Circuit Design i

dominated by Synopsys, and OVM is developed by Cadence and mentor. 6. assert is a good thing. Assert is very powerful and easy to use. It is precisely because of its advantages that it can discover design errors and locate problems accurately, so the verification engineer cannot use it very easily, because the verification engineer generally can verify the design module without having to know too much design details, but assert needs to have a clear understanding of the internal signal, to co

, the relationship is still stuck in the relationship between object Orientation Analysis and Design. After all, the tool will complete the practices of COM + and Web Service. The same is true for SoC Development. with EDA tool, more and more integrated, the more integrated the design IC is, in addition, most of the actual work has been completed by EDA tool. Only analysis and design can be performed by humans. In order to conquer the attention and re
