| 09:07 | sagnikbasu95 | Hi Bertl..
|
| 09:08 | Bertl | hey, how's going?
|
| 09:11 | sagnikbasu95 | I was just wondering why do use Xilinx FPGA for your axiom..What about other small form factors like Microsemi Igloo?
|
| 09:12 | Bertl | we wanted to find a reasonably priced FPGA development board which also has a small size for the Beta
|
| 09:12 | Bertl | this narrowed the available options down to boards like the MicroZed and the Parallela
|
| 09:13 | Bertl | back then, it also was a bonus that we already knew the ZYNQ from the Zedboard (which was used on the AXIOM Alpha)
|
| 09:14 | sagnikbasu95 | Do you require any license agreement with Xilinx for using their FPGA for your product ?
|
| 09:14 | Bertl | but there is really no special reason for Xilinx, we also use the Lattice FPGAs on our boards for routing
|
| 09:14 | Bertl | all FPGAs can be used with the 'free' licenses (WebLicense, etc)
|
| 09:15 | sagnikbasu95 | Like as students we also use Nexys 4 and Zedboard but our institute had to buy student licenses for the software.
|
| 09:15 | Bertl | that is something we made sure, otherwise it wouldn't be very suitable for a FOSS/OH projects
|
| 09:16 | Bertl | actually both the Nexys and the Zedboard should be covered by the WebLicense IIRC
|
| 09:16 | Bertl | so you can program and use it, you won't get special Xilinx IP for free though
|
| 09:18 | Bertl | yeah, just checked, the Nexys 4 has an Artix XC7A100T in CSG324
|
| 09:18 | Bertl | which is covered by the free Web License
|
| 09:18 | arpu | left the channel |
| 09:19 | sagnikbasu95 | Yeah...I think maybe our institute brought the license to IP core...
|
| 09:19 | Bertl | that's possible, we don't use any of the Xilinx IP cores
|
| 09:20 | Bertl | although some of them come for free, but we didn't want to add any proprietary parts to the design
|
| 09:20 | Bertl | it just complicates things when you are searching for a bug
|
| 09:23 | Bertl | https://www.xilinx.com/support/documentation/sw_manuals/xilinx2016_4/ug973-vivado-release-notes-install-license.pdf (has a list of WebPack supported devices)
|
| 09:25 | Bertl | btw, the Microsemi devices are really interesting, but their toolchain is really bad, especially on Linux
|
| 09:25 | Bertl | (although, that might have changed since I last tried a year ago or so)
|
| 09:26 | Bertl | Altera has nice devices as well, but they do not provide any reasonably priced development boards at all
|
| 09:35 | Bertl | but we should definitely make a list of interesting FOSS/OH compatible FPGA boards somewhere on the wiki (with some details about price and features)
|
| 09:39 | sagnikbasu95 | yeah that would be nice...
|
| 09:41 | Bertl | well, we already have this page: https://wiki.apertus.org/index.php/Zynq_Development_Boards
|
| 09:41 | sagnikbasu95 | i always wanted to try a altera board...or the actel anti-fuse fpga...but their are too costly..only place i saw them
|
| 09:41 | sagnikbasu95 | are in R&D labs of big industries
|
| 09:41 | Bertl | so maybe generalize that and/or integrate it in a more general FPGA dev board page?
|
| 09:43 | Bertl | there is a good list of FPGA devel boards available here: https://joelw.id.au/FPGA/CheapFPGADevelopmentBoards
|
| 09:43 | Bertl | but it is unclear what licenses they use/require
|
| 09:43 | Bertl | and of course, stand alone boards (i.e. without carrier) are nice but usually not suitable for an AXIOM
