In the PCB design method based on signal integrity computer analysis, the most core part is the establishment of the PCB board-level signal integrity model, which is the main difference from the traditional design method. The accuracy of the SI model will determine the correctness of the design, and the buildability of the SI model determines the feasibility of this design method.

In the design of high-speed pcb, a large part of the work is to carry out the noise budget and plan the noise level generated by various noise sources of the system. This involves a very basic but very important concept: voltage tolerance.

2021-08-25

Many people are very vague about the concept of the critical length of lines on the PCB, and even many people don’t know this concept at all. If you design a high-speed circuit board but don’t know this concept, you can be sure that the final circuit board may not work stably. , But you are at a loss and have no way of debugging.

Signal rise time is critical to signal integrity,high speed PCB design problems are mostly related to it, need to pay attention to.

2021-08-25

I mentioned in the previous article that we should pay attention to the signal rise time. Many signal integrity problems are caused by the short signal rise time. This article will talk about a basic concept: the relationship between signal rise time and signal bandwidth.

2021-08-25

Signal integrity issues involve a wide range of aspects, here is just a brief introduction to a few phenomena, I hope this article will give you a preliminary understanding of signal integrity. Signal integrity will be a required course for every hardware engineer. Contact one day earlier and benefit one day earlier.
