Answer: 1. Basically, it is right to divide and isolate the modulus/number. It should be noted that the signal line should not be crossed through a separate place (moat), or the returning current path of the power supply and signal should be too large.2. the crystal oscillator is a simulated posit

Answers to four questions about the shielded Cabling System
In integrated wiring, two types of wiring are classified from the largest category: unshielded wiring and unshielded wiring. the unshielded wiring was first originated in Europe, it mainly adds a metal shielding layer to the external of a common unshielded wiring system. The principle is to use the emission, absorption, and skin effect of the metal shielding layer to prevent electromagnetic interference and electromagnetic radiation, t

This is an exciting news! With the importance of verification in icdesign being paid more and more attention, EDA giants are launching new strategies to attract potential customers. From AVM open source to OVM open source to vmm open source, we can see a series of positive initiatives that are constantly pushing for

There are many available structure types, including the XML class of the Jakarta Element construction kit (ECS) project to a parser that fully complies with Dom specifications, such as xerces, usually, the smaller the version, the simpler the XML output method. List B is an example of using ECS.
Listing B provides a concise method for outputting data. In fact, you can combine two output rows into o

Problems related to shielding systems in Integrated Wiring
In the Integrated Wiring System, unshielded and unshielded systems are widely used. The shielding system comprehensively utilizes the balanced principle of twisted pair wires and the shielding effect of the shielding layer. It has good electromagnetic compatibility and can prevent electromagnetic interference and electromagnetic radiation.
The advantages of shielded cabling can help the rapid development of the Internet. Many large dat
