It is said that ： How many good answers , I've been waiting for a good question all my life . Today, Mr. expressway is not normal , Ask only questions, not answers , See if the following question can attract some good answers .

Recently, I found such a dialogue in a customer communication group , It triggered my idea of building a high-speed Mr. Q & a Hall . The previous articles have always been written by us , Fans also allow me to steal a little lazy in this issue . In addition, at the successful headquarters seminar last week , We felt the enthusiasm and professionalism of the friends at the scene in answering questions , I believe that there must be many experts in Mr. Expressway's fan group , Just don't speak normally , The ability of fans has been suppressed for too long , You should also screw it out occasionally to bask in the sun ！

In fact, the customer didn't want to meet our Mr. Expressway team at the beginning , Oh, No , Yes , First of all, the customer found the marketing manager of one of our branches , So there is a simple and efficient dialogue between the customer and our marketing manager ！

Then most of our marketing managers are experienced , After a brief review of the data , And realized that “ The seriousness of the problem ”, At the first time, our Mr. Expressway team and customers will be brought into a communication group ！
Then Mr. Expressway succeeded in taking over the group , The conversation started between Mr. Gao and the customer .

Originally, the customer came prepared , They're doing this PCIE4.0 Before the project , It has been successfully completed 3.0 Commissioning of the project , And according to them ,4.0 The version of is basically the same in structure 3.0 The versions don't differ much , So the customer felt that they could directly “copy” Just design , There is no significance of simulation . After Mr. Gao listened to the customer's description , Or get it first PCIE3.0 Version of PCB file , Evaluate and then draw a conclusion .

When Mr. Gao carefully evaluates what the customer said demo Behind the plate , Continue the conversation with the customer .

Through dialogue with customers , It is found that customers still understand some conventional high-speed theories , It seems that it is not necessary to simulate this project , But the customer showed enough grace , Or did he say he would patiently listen to Mr. Gao's views .

Therefore, Mr. Gao made a specific analysis and risk point prompt on the design details from a very objective position , The dialogue is as follows ：

feed , Is the editor wrong , Give the mosaics the most important content ！ Uh , sorry , That's what Mr. Expressway meant, huh , We want to take the content of this mosaic as a question for the majority of fans to answer , The purpose is to improve everyone's interaction （ Reply answer -- Official account of Mr. high speed ）！

As long as we can give reasonable reasons , Customers will also be on the rational side , Choose to consider our suggestions .

All right. , The chat is over , I said before. , In this issue, we mainly let the fans speak , So in theory, everyone replied that we could do anything , Mr. Gao gives you some references to reply ： 

1. Discuss what might go wrong , Or there are risks ;

2. Discuss your views and ideas on this issue ;

3. Or limit some conditions , Then it is concluded that under such conditions , The design can ensure the signal quality ;

4. You can also not answer questions , Instead, ask your questions ;

5. Anything you want to say is OK .
