Without layering, you won’t be able to draw a board [Copy link]

 

I am used to AD hierarchical schematics and harnesses, and now I can’t live without them anymore. The most prominent advantage is that it is much more efficient to check design errors with hierarchical diagrams than with flat schematics. Although the page spans of flat schematics can also show which pages the network is connected to, it is still inconvenient to check them one by one. Moreover, some relatively disabled software (mentor EE) does not support displaying the page number next to the page span. In this case, if you want to ensure that all networks are correctly connected and the board is successful, you can only pray for God’s blessing.

AD This feature is really good, and the schematic is clear and beautiful.

The schematics I draw now are simple, and I have not yet experienced the hierarchical diagram function of AD.

I have to process a 32-page schematic, and the page span cannot display the page number. I am about to explode.

How big a board is, how many pages of schematics are needed? Can several people work together to draw a schematic for a board?

More complex embedded systems and general desktop hardware are of this scale

I haven't used AD to draw for many years, and I have never drawn a hierarchical schematic diagram.

What is the success rate of one board?

Fortunately, there were no mistakes. The main reason is that my board is not that complicated.

There is a 1000 pin or more board, and it can guarantee 100% success without a hierarchy diagram, which is amazing.

It depends on the situation. If the circuit board is relatively simple, a hierarchical diagram is still required. AD also supports module reuse.

KICAD has the same function, and it is open source and does not often receive lawyers' letters.

I don't like reusing modules, I always have to make a lot of rooms

If you don't design the schematic diagram according to the hierarchy diagram, you will sometimes have to search for related principles on multiple pages, which is really frustrating.

It seems that AD already has the function of drawing schematics with multiple people working together

Your board is quite advanced.

Actually, it is nothing. Only when everyone's computer can display other people's actions in real time like playing games can it be true collaborative operation. Current PCB software does not do this. Cadence and Mentor claim to have done it, but watching their demonstration videos, they are still stuck. It takes 2-3 seconds for one person to operate something before it is displayed on other people's computers.

This function is really useful. By the way, I would like to ask why RS485 and W5500 have a triangular shear mark?

The arrow indicates that this is a schematic submodule that has been made into a device sheet, which means module reuse. But I don't like this thing very much. The component position numbers and network names of the device sheet cannot be modified, and the component numbers also need to be marked at the board level to avoid conflicts, which is not conducive to reading the diagram. I still prefer to convert the device sheet back to a normal schematic.
