  1. Re: Why are poorly supported pcb layout packages so popular?

    So far, so good. I haven't had time to dig deep into the program yet but one positive right off the bat was I was able to go to the cadsoft website and download the program, then immediately...
  2. Re: Why are poorly supported pcb layout packages so popular?

    I have to admit you make a good point. I'm not an Eagle user, but often hear the same comments, and looking at some example designs done in Eagle, I jumped to the conclusion that it's not a "serious...
  3. Re: Why are poorly supported pcb layout packages so popular?

    I have givin Eagle a good look and honestly, it does seem best suited for hobbyists or students, and there is nothing wrong with that. A power user could very well do a fairly sophisticated design,...

    I never had any luck with the Altium autorouter and after seeing what a real autorouter looks like, Altium should dump the one they have and start over with a new one from scratch. Reading the...

    Not sure if this will help you but one option is to just import as DXF and assign to the appropriate layer of your design and don't forget to assign a net. As you may already know Altium isn't a...

    There are actually two types of eye diagrams: the usual digital eye diagram and there is also a I-Q eye diagram. It sounds like your looking for the digital eye diagram. ADS has some nice tools for...

    Does anyone have a semi up-to-date Altium Basic Training Manual? Altium used to have a big 20 chapter manual available for download on their website, but they removed it and now demand...

    Thank you for sharing! Looks like a very good one and indeed more reasonable over the very ridiculous pricing Altium charges.

    Thanks for confirming senilicus. I was fairly certain it was some sort of compressed file, kind of like gzip, but wasn't 100% sure.

    If I'm not mistaken, the .tgz file format is a compressed file. Maybe you should check first if you can extract the contents of this file and see what it has first? I'll take a guess it will be a...

    Thank you for the reply. I'm looking at the HFSS official quote and your right, the software is not over $100K. It's $95k, so I was off by about $5k. (Core program, Ansoft Links, Optimetrics, and...

    Closed: Does Feko have the same capabilities of HFSS?

    Feko says it provides multiple computation methods such as FEM, MOM. Having both these methods seems like a very powerful tool.

    HFSS uses FEM.

    Does Feko have the same capabilities as HFSS? ...
  19. Closed: Re: Current flow in a planar transmission line during a spurious mode

    Thank you so much for the follow up. Ok, I think I get this. It makes sense and can explain why with spurious modes, those can also be seen as dips in the frequency domain response. What got me...
  20. Closed: Re: Current flow in a planar transmission line during a spurious mode

    Thank you for the reply. It makes sense what you say. The thing I'm confused with is when hearing the perspective of a high-speed digital engineer focused on signal integrity. They have it...
