Bertl_oO: will a 7 bitslips be the same as 1 bitslip in a xilinx 6:1 iserdes?
00:23
anuejn
context: i have a 2:1 fabric gearbox after the iserdes
00:24
Bertl_oO
good question!
00:25
Bertl_oO
let's see what ug471 says about it ...
00:25
anuejn
it only talks about repetitive patterns :(
00:26
Bertl_oO
page 158 Bitslip Operation
00:29
Bertl_oO
the example on page 160 shows that at least for 4 outputs the pattern has a 4 slip cycle
00:30
Bertl_oO
so I'd conclude that on a 6:1 gearing, the cycle length would indeed be 6
00:32
anuejn
hm... i wouldnt conclude that from the example on page 160
00:32
Bertl_oO
but, I remember that there are certain limitations to the modes
00:33
anuejn
since they have a 4 bit training pattern
00:33
Bertl_oO
i.e. the documentation clearly states that the bitslip only works in network mode
00:36
Bertl_oO
well, there are two options how the explanation can be interpreted
00:36
Bertl_oO
either the bitslip operation has _always_ 8 steps in a cycle
00:36
Bertl_oO
or it does have as many steps as the data width is
00:37
Bertl_oO
with a given test pattern, and any odd data width this should be trivial to verify, no?
00:37
anuejn
more or less
00:37
anuejn
but not today...
00:38
anuejn
thanks anyways :)
00:38
anuejn
good night
00:38
Bertl_oO
no problem and sorry that I couldn't help much
00:38
Bertl_oO
btw, you can directly connect an OSERDES to the ISERDES
00:38
Bertl_oO
so this might be the simplest way to test this

morning folks!
09:32
Xaxamiun
mornings, new here.
09:32
Xaxamiun
Be interesting to see if I can contribute to this project in some way in the future
09:33
Bertl
hello Xaxamiun! sounds good!
09:34
Xaxamiun
As a heads up. I am a Javascript developer (React.JS, NodeJS, MongoDB)
09:37
Bertl
best check with se6ast1an then ... I'm the hardware person :)
09:38
se6ast1an
Currently at lunch, will be back in 20 minutes
10:03
se6ast1an
hi Xaxamiun!
10:03
se6ast1an
back now
10:04
se6ast1an
what would interest you in general?
10:04
se6ast1an
did you already have a look at the task in our taskmanagement system?
10:04
se6ast1an
https://lab.apertus.org/
10:05
se6ast1an
I know there are a lot and it can be overwhelming at first
10:05
se6ast1an
but maybe you still find an area that would spark your interest
10:13
anuejn
also there is https://github.com/apertus-open-source-cinema/webui which is our current attempt to build a webui for the beta
10:14
se6ast1an
yes that would be a good match for javascript, etc.
10:14
anuejn
the wip sections from the readme are things that are not yet implemented but definitely planed :)
10:15
anuejn
and nice to work on
10:22
anuejn
(the dashboard is already implemented)
11:05
Xaxamiun
Hey, sorry was AFK.
11:05
Xaxamiun
Will definitely take a look at the webUI project as well as the forums
11:11
Xaxamiun
the WebUI seems like it might be a good place to start, I see it uses Reactjs
