#apertus IRC Channel Logs

off for now ... bbl

probably :)

hi Max

great you joined the channel immediately!

so what do you think about this?

bertl created all the AXIOM Beta hardware so far

maybe a plugin module

we mostly used Eagle for the current designs

Is something like Altium Designer and/or Cadencce Allegro acceptable? I own license for Altium

and if you want to change anything you need to pay big bucks as you probably know

sure, I understand this - maybe it's possible to use sort of 3d party format, something not CAD-specific?

let me investigate this

well, from what I can see there are importers from Altium to Kicad (http://www.eevblog.com/forum/kicad/importing-altium-pcb-into-kicad/)

from what I found at the moment it looks like even schematics can be imported

make sure it works fine, i.e. get a design you already did and convert it completely and check that everything is fine

alright, I'll test those importers later today and get back to you with results

ok, I'm leaving for now to finish some stuff and then proceed with mentioned things- so I hope we will talk soon:) BB

KiCad is a very promising open source EDA solution

ah!

Hi again Bertl - we've discussed today possibility of Altium to Kicad export in context of possible PCB design contribution

I've tried couple things with Kicad and failed :)- don't have any idea how to even proceed with that sort of guide from existing import links

that was what I feared ... :/

what I remember from the last time I read about it, that it requires the files to be written in a special ASCII version from altium

what seems bad also- a fact that guys which somehow managed to proceed with import, the report about bags and missing copper

well, we won't stop you from contributing to the project because you use altium

also I do not think that it is a good choice to store design data in a proprietary format which is mostly unknown

yes, I understand that - but probably it's worth to try, as I'm very proficient in Altium xD

never tried an Altium import in Eagle

maybe give that a try, we are working on an Eagle to KiCad export

there is a lot which can be worked on, for example we plan for a 4K HDMI out plugin module

but there are other areas as well, like for SDI

are you already familiar with the existing designs?

well, it would probably be a good start to get comfortable with it, as all the parts work together somehow and there is not much which can be completely separated

an SDI plugin is for sure something nobody is currently working on and everybody would like to see :)

so what will be the starting point? BTW, how collaborators are contacting each other? Do you have some "corporate standards" in design methodology, workflow etc.?

we try to conform with plugins, shields and boards to the OSHpark 2/4 layer standard

I see - so these : http://docs.oshpark.com/services/, are design rules for PCB, right?

but if there is a real need for going beyond that, we can make an exception, especially for more expensive plugins or addons

(e-Mail is also fine when it makes sense)

depends on how you define high-speed stuff

well, length matching is not a problem with OSHpark

but of course, you have to do the work on getting the impedance right

http://docs.oshpark.com/services/four-layer/

how desings are submitted and reviewed? Do you use versions control system of any kind?

we have a repository on github where we try to check in the designs when they are worked on by more than one party

gthub works good for me

for the SDI plugin, get intimate with the plugin interface and the size of those plugin modules

where I can get info about/project files this? It's in your repository?

http://vserver.13thfloor.at/Stuff/AXIOM/BETA/

check out the 1xHDMI and 3xPMOD plugins for the plugin sizes and connections

ok, I looked at that stuff - about that SDI module, what's current status if it? Any constraints, requirements, schematic drafts?

nobody started to work on that yet, so current status: planned

just ask if something is unclear

1)you have sort of board that is stacked with Microzed board 2) there are kind of expansion boards(modules)3) there should be kind of SDI expansion board

the rest is in dark :)

probably I could understand the main concept looking at this:http://vserver.13thfloor.at/Stuff/AXIOM/BETA/PCB-Stack-Concept-V03-02-nofan-50-Bertl.jpg

in relation to entire system of course

hi derek!

great to see you here

no worries

actual perfect timing as I just returned to the pc :)

excellent!

some things with the enclosure design are not obvious

I was just checking out the github

collecting the files together, creating a wiki page what to keep in mind

in case this is something you would want to do?

great

no thats the right one

the simple design is https://www.apertus.org/sites/default/files/AXIOM-Beta-Simple-Enclosure-Explosion01.jpg

great

version 2, skeleton, simple enclosure, etc....

What was the motivation for this project?

https://www.apertus.org/about

haha, touche

I guess, I meant more personal motivations? but I'll digest this more.

davidak: that is something which never works well and typically results in very bad designs :)

you can see how problematic this is with FPGA tools

maybe SI could solve that someday

yep, probably ... you can try it yourself with the autorouter on existing designs

the result is typically very sad :)

component placement is even more problematic and similar to chess/go the search space explodes very fast

back now ...
