Watch routing PCB Layout with DDR3 & High Speed Interfaces

Thank you very much to Blaine for the music!

Hi Vladimir. Screenshots every 20 minutes of each layer during the whole design - and then merged into this video. Very big thank you to Martin who was doing it. BTW: your video is nice - THUMBS UP!

[RobertFeranec]

Thank you. I have learned a lot from design guides. I do not have any special electronic books - a lot of things I need during design are very specific and I just find them on the internet.

Who needs to take LSD when you can do PCB design :D

Man, this is fascinating. It kinda looks like a piece of art. I would definitely print that layout and hang on a wall !
I have only small experience with PCB design, but i am getting better. Maybe one day i will work on a project of this scale too.
Best regards Jan

you are the god of Altium Designer "Robert". You are awesome.

[prudvi]

This is beautiful! I can only dream to create such a masterpiece

[LeexTheFirst]

I've designed very simple PCB boards with KiKad using resistors, transistors, etc. Lemme tell you, it took me forever just to do a simple PCB haha. Never in a million years will I design any motherboard.

Thank you for sharing Robert! (How) did you do the Signal Integrity/Power Integrity?

[mquintus]

My god... I'm sitting here designing a "simple" microcontroller-board with filters and relays (2 layers max.) And almost giving up... Makes me really appreciate this video!

It might be little difficult to make such PCB at home, using iron and toner transfer paper.

This covers the layout, but what about simulation to ensure that the power delivery network works and also that the high speed interfaces work as they should?

[dmw]

excellent！could you tell me what‘s your reference when routing high speed signals like pci-e or ddr?

[عبدالعفوهقي]

Hello, Professor. Do you have an academy for teaching electronics?

[優さん-nm]

How many PCBs of this nature has Robert done in this career?
Doing dense PCB design takes a lot of time. Doing it together with writing firmware and other aspects of the project are likely not possible.

Hi, this design is just a piece of art.

i'm new with PCB Design using Altium Designer, are there any design rules, or guidelines/ best practice that you would advise me ? ... Thank you

When you're routing Address lines, you have different length traces in top and bottom layers (near RAM chips), compared to each address line. As an example, in this board A6 line has 6.83mm length in top and bottom layers (outer layers). but A0 has only 2.184mm in each outer layer trace. However, both A6 and A0 has length matched to 20milis.

What I'm wondering is, this mismatch in lengths in top layer portions of each address line trace, wouldn't it have different propagation delays? We know that the outer layer traces transmit significantly faster than inner layer traces. So even though the address and command lines are length matched to 20milis, wouldn't it still have a propagation delay mismatch? which is the main purpose of matching trace length?

Isn't the right thing to do is actually match the lengths of all traces in each layer?

Simply Art - thanks a lot! Learning to do DDR3 from you <3

Hi Robert, very impressive. Is this done with full autorouting or manual routing ?
(I have bad experiences using full auto routing in the old protel 99, very poor EMC results, and it never completed 100%. Maybe partly by not having enough rules)

[tcentolanza]

I’ve worked with FPGA/BGA Altera with Mentor Graphics, and this is really fascinating, auto router ( you must setup) creat all rules, amazing job !

[edlubitz]

I've always wondered how you keep the currents separate with all the overlapping, sounds lame I suppose but doesn't make a whole lot of sense to me.
