I'm wondering what the purpose of your post is.

- Advertising your USB scopes?

- Advertising or just recommending PCBCAD51 as a happy user?

- Sharing some of the things you've learned about layout involving high speed signals? (But in that case, please share links to some of the websites or other materials you've found helpful for high speed signal layout.)

Just curious. It's all fine with me, including advertising. Last time I read the rules for this newsgroup (probably 15 years ago!) I think it said one advertisement per month for things relevant to this group is OK.

You might also consider posting to the electronics101 Yahoo group.

Re high speed signal design and layout: I'm currently taking the online, self-paced training for Mentor HyperLynx SI and PI (Signal Integrity and Power Integrity) packages??. It's an amazing bit of software, useful for designing and laying out multi Gb/s signals. For example, you can specify a board stackup, enter a schematic of a trace (including driver and receiver characteristics, trace (transmission line) lengths and impedances, vias and their characteristics, branches, terminators, etc... and then run simulations and see simulated oscilloscope traces of the signals. That's a pre-layout activity. Post layout, you can extract the trace schematics from the layout and run the simulations again to verify that the layout will work. The simulations can also account for crosstalk.

Mentor makes makes their online, self-paced training available for free to unemployed engineers. Bravo to Mentor for doing that! Of course it's in their self-interest to do that, since people who take that training will spread the word about the product (as I did above) and want to use the software in future jobs.

I've received free training from several other software and semiconductor companies as well. It pays to ask!
