|
| 17:05 | mithro | Oh, oh! If you are rewriting the apertus gateware in nmigen then we should certainly chat!
|
| 17:11 | Bertl_oO | definitely!
|
| 17:12 | Bertl_oO | felix_: look, somebody implemented SDI :)
|
| 17:47 | felix_ | don't see any fpga design code in there though
|
| 17:51 | Bertl_oO | maybe mithro knows more ...
|
| 18:07 | mithro | Bertl_oO: Sadly, no still uses closed source SDI cores
|
| 18:07 | Bertl_oO | that's a pity
|
| 18:12 | mithro | Bertl_oO: Still working on solving that problem
|
| 18:20 | felix_ | i've been quite busy with my new job at AMD working on coreboot and didn't get around to continue working on photonsdi yet :(
|
| 18:27 | mithro | Bertl_oO: We are getting a lot of zynq support into the open tools
|
| 18:28 | mithro | @Bertl_oO: And things like partial reconfigurable regions which let you use part of the design on Vivado and part in the open tools
|
| 18:29 | felix_ | that sounds awesome
|
| 18:30 | Bertl_oO | mithro: so do the open tools now support the zynq 7020 completely?
|
| 18:30 | Bertl_oO | (last time I checked not even the fuzzers worked as expected)
|
| 18:30 | mithro | Bertl_oO: Depends what you mean my "completely"?
|
| 18:31 | Bertl_oO | well, AXI, SERDES, delays, etc
|
| 18:31 | mithro | Bertl_oO: https://github.com/SymbiFlow/symbiflow-arch-defs/pull/1506
|
| 18:31 | mithro | [Merged] Zynq 7020 support #1506
|
| 18:32 | Bertl_oO | yay! not even a month ago \o/
|
| 18:32 | mithro | Bertl_oO: DSP / GTPs still need to be decoded -- but the PR flow enables you to keep parts in Vivado and incrementally move more and more into the open source tools
|
| 18:33 | mumptai | wonders if that finally makes the zynq self-synthesizing
| | 18:33 | Bertl_oO | mithro: parts in vivado? how does that work?
|
| 18:34 | mithro | mumptai: In theory -- in practice it needs a lot of work
|
| 18:34 | mithro | Bertl_oO: We can "stitch" together bitstreams from multiple sources
|
| 18:34 | Bertl_oO | does that support relocation as well?
|
| 18:34 | Bertl_oO | or how do I do that with e.g. DSPs?
|
| 18:35 | Bertl_oO | (we do a lot of stuff in DSPs :)
|
| 18:36 | mumptai | mithro, nice :-)
|
| 18:36 | mithro | Need someone to do -- https://github.com/SymbiFlow/symbiflow-examples/issues/26
|
| 18:37 | mithro | Bertl_oO: for the DSP stuff, we probably need to make that better
|
| 18:37 | mithro | Bertl_oO: you can also use Yosys --> Vivado
|
| 18:38 | Bertl_oO | does yosys do VHDL now?
|
| 18:39 | mithro | https://github.com/enjoy-digital/litex/pull/551 -- Add Symbiflow toolchain support for Xilinx 7-series #551
|
| 18:39 | Bertl_oO | ah yes, there seems to be a ghdl plugin ... but experimental
|
| 18:39 | mithro | Bertl_oO: The j-core and microwatt people are using it pretty heavily it appears
|
| 18:40 | Bertl_oO | definitely have to check that out
|
| 18:41 | mumptai | i don't understand why the fsbl config has to be fuzzed, is the documentation so bad? or some legal reason?
|
| 18:42 | mumptai | there is a lot of stuff to be configured, but most should be described in the reference? also everybody just uses the ps-init from the vivado projects
|
| 18:42 | Bertl_oO | mithro: so what's the interface between yosys and vivado?
|
| 18:43 | mithro | EDIF
|
| 18:43 | Bertl_oO | but pre routing/placement?
|
| 18:45 | mithro | Yes
|
| 18:45 | mithro | http://j.mp/symbiflow-status-doc
|
| 18:47 | Bertl_oO | so that is probably not a big advantage then
|
| 18:47 | Bertl_oO | as synthesis is pretty fast in vivado
|
| 18:48 | Bertl_oO | anyway, good to know that there is progress
|
| 19:15 | mithro | Bertl_oO: getting your design goes into Yosys is the first step to using the open source toolchain
|
| 19:15 | mithro | Also it lets you compare the open source PnR verse vivado
