again, ideally adjustments are done all the time, e.g during idle periods
00:03
Bertl
but for a start, that's probably fine

I will try making DDRx4 work again as handling 64bits words from 5 channels is going to be difficult i think

morning folks!
13:51
aSobhy
Good morning Bertl :)
13:54
aSobhy
I've a question: how can I trace the wire from the MaxhXO2 to ZYNQ?
13:56
aSobhy
I want to connect the LVDS wires and the reset from the pins I specified at the MachXO2 side to the corresponding ZYNQ pins
13:58
Bertl
ah, you need to check the wire names on the schematic
13:58
Bertl
they use similar names to the MicroZed names
13:59
aSobhy
that's great :)
13:59
Bertl
for the RFW it is BANK13_01_{P,N}
14:00
Bertl
for the RFE JX1_05_{P,N} and JX2_04_{P,N}
14:00
Bertl
(for the LVDS)
14:00
aSobhy
yes yes I found them
14:01
Bertl
for the MicroZed there is a pinout table
14:01
Bertl
where you can see the Zynq Pin numbers for each name
14:02
Bertl
there the names are slightly longer with _LVDS_ between JX1/JX2/BANK13 and the number
14:03
aSobhy
OK
14:04
Bertl
all sorted or something still missing?
14:05
aSobhy
yeah their is another question
14:05
Bertl
let's hear then
14:07
aSobhy
I cant find the pins name of the top module as to continue assigning as in the user guide
14:07
aSobhy
the top module doesn't show its pins in the Netlist
14:09
aSobhy
I've created a top file top hold the train file(main) and the output was the same
14:09
aSobhy
It makes it nested and didn't show the pins?!!
14:10
aSobhy
I'm following that
14:10

https://www.xilinx.com/support/documentation/sw_manuals/xilinx2012_2/ug945-vivado-using-constraints-tutorial.pdf
14:10
Bertl
okay, please upload/commit the project, I'll take a look
14:10
Bertl
(paste a link here or via pm)
14:12
aSobhy
yeah Its up to date

14:28
Bertl
the tcl script fails here for me
14:28
Bertl
ERROR: [Common 17-53] User Exception: No open project. Please use Save Project As to save your work and re-do this operation.
14:28
Bertl
what vivado version do you use and how do you build it?
14:30
aSobhy
17.4
14:31
Bertl
okay, that's the same here
14:32
Bertl
vivado -mode tcl -source vivado.tcl
14:32
Bertl
(is what I used)
14:35
aSobhy
actually I don't use the tcl for now
14:35
aSobhy
its doing the same thing at my side
14:35
Bertl
so how do you build it?
14:36
aSobhy
from the GUI
14:36
Bertl
don't see any project file either
14:37
Bertl
please give some instructions how to replicate your issue
14:40
aSobhy
OK I'll fix the TCL file

aSobhy: what's the status?
21:16
aSobhy
I generated the TCL using:
21:16
aSobhy
write_project_tcl top.tcl
21:16
aSobhy
It generates the tcl but It is for my pc only with my paths I tried with absolute_path It is the same with little changes
21:17
Bertl
so what is the plan now?
21:18
aSobhy
I'm trying to set them like in that file https://github.com/apertus-open-source-cinema/axiom-beta-firmware/blob/master/peripherals/soc_main/pin_spi_ibc.xdc
21:18
Bertl
which obviously works
21:20
aSobhy
and Its running now I'll tell you if it fails or pass after it finishes
21:20
aSobhy
ok I hope so
21:20
BAndiT1983
changed nick to: BAndiT1983|away
21:20
Bertl
so I'm more curious, how do you plan to address the 'nobody except you can build your project' part?
21:22
aSobhy
I didn't catch !
21:22
Bertl
currently your repository is useless as nobody (except you) can rebuild it
21:22
Bertl
how do you plan to change this?
21:26
aSobhy
It took alot of time and I managed to fix it after that test
21:26
Bertl
so it can now be built by somebody else?
21:26
aSobhy
should it differ from windows to Linux
21:27
aSobhy
I think no
21:27
Bertl
depends on what you did :)
21:28
Bertl
in any case, it would be a good idea to setup a Linux VM and install the tools there to simply test your repository when you think it 'should work'
21:29
aSobhy
but "write_project_tcl" generates the tcl with the local paths from my pc
21:29
aSobhy
should I remove it manually ?
21:30
aSobhy
by comparing it with the file vivado.tcl it has the absolute paths
21:31
Bertl
personally I'd suggest you write the build tcl yourself
21:31
aSobhy
I have linux beside windows but I failed to install it
21:31
Bertl
similar to the vivado.tcl used in the AXIOM Beta sources
21:32
Bertl
but of course you can adjust the generated tcl as well as long as it works
21:36
aSobhy
ok I'll give a try that night
21:36
Bertl
"but I failed to install it": what didn't work?
21:37
aSobhy
It takes too much time installation comparing to the time it takes on windows
21:37
aSobhy
and its the offline version
21:39
Bertl
I don't know how long the Microsoft Windows version takes, but the Linux version took about 8 minutes for a complete install here
21:39
Bertl
(talking about Vivado)
21:40
aSobhy
it take about 2 hours so I terminate it on ubuntu
21:40
aSobhy
yes I'm talking about Vivado
21:41
Bertl
was that in a VM or on real hardware?
21:42
aSobhy
real HW
21:42
aSobhy
windows along side with ubuntu 18
21:42
Bertl
that sounds very unusual, you sure you didn't run out of memory or disk space?
21:43
Bertl
I know that Vivado is quite demanding (space wise)
21:43
aSobhy
I give ubuntu 100 GB
21:43
aSobhy
gave*
21:44
Bertl
that should suffice
21:44
aSobhy
and tried with ubuntu 16 & 18
21:45
Bertl
maybe next time try with a different distro
21:46
Bertl
also check the Xilinx forum for installation issues
21:46
Bertl
I remember that there have been some problems with certain releases

the run failed :/
22:14
aSobhy
the pins didn't change from their places
22:14
aSobhy
I'll fix the tcl file so you can help me
22:15
Bertl
please do so
22:15
Bertl
let me know when you encounter issues with the tcl
22:17
aSobhy
OK I'm on it now
