| cr1901 | Wow, the uhdm plugin is next-to-impossible to compile locally | 04:44 |
|---|---|---|
| cr1901 | I give up... I hope I don't need it | 04:44 |
| cr1901 | can't find uhdm, can't find surelog, recompile with -fPIC | 04:45 |
| cr1901 | Ahhh finally... need to pass -DCMAKE_POSITION_INDEPENDENT_CODE=ON to Surelog and use Surelog's copy of UHDM | 05:00 |

| sf-slack | <tgorochowik> cr1901: we use this integration repo to build everything: https://github.com/antmicro/yosys-uhdm-plugin-integration it contains all the dependencies as submodules and has a build script that puts everything together | 09:29 |
| sf-slack | <tgorochowik> a proper readme/manual is needed though! we certainly plan to write one | 09:29 |

| cr1901 | tgorochowik: For development purposes it's easier if I use my own personal copy of yosys and have the plugins be loaded by my copy/branch | 16:18 |
| cr1901 | However, this didn't go to plan b/c I managed to make dram_test_64x1d_bit segfault | 16:19 |
| cr1901 | My copy of yosys isn't that far off the conda copy... is the conda copy patched in some way that's not upstream? | 16:19 |
| cr1901 | But I did manage to get it compiled/wrote it down | 16:21 |
| sf-slack | <tgorochowik> yes and no, we do have a patched yosys that adds some new features, however the plugin should also work with mainline yosys (to which we also contribute things we need for better systemverilog support) | 16:22 |
| sf-slack | <mkurc> cr1901: The version string of the conda package contains SHA of the git revision. I'm not aware of any changes to it made during packaging. | 16:22 |
| sf-slack | <tgorochowik> what is important though is that you use compatible surelog/uhdm/plugin repos, this flow is still under heavy development so if you take everything from mainline it may not work - that's why the integration repo holds proper submodules with those | 16:23 |
| cr1901 | I don't think the uhdm plugin is crashing | 16:24 |
| cr1901 | Something's not right on my end, hmmm... | 16:25 |
| sf-slack | <tgorochowik> we'll be happy if you file a bug in case you find any issues with the plugin or yosys with the plugin, we'll take a look at it then to help you push it forward | 16:26 |
| cr1901 | I can do that, will have to minimize first tho :D | 16:26 |
| sf-slack | <tgorochowik> but just to be on the safe side, you can use the repo I mentioned above, the script has a --skip-yosys arg (https://github.com/antmicro/yosys-uhdm-plugin-integration/blob/master/build_binaries.sh#L11) meant specifically for a use-case similar to yours (externally provided yosys) | 16:27 |
| cr1901 | ""make dram_test_64x1d_bin" with my own copy of yosys and plugins crashes" isn't exactly helpful | 16:28 |
| cr1901 | tgorochowik: Ack: re skip-yosys | 16:28 |
| cr1901 | The only thing that's different from my install so far is I pass BUILD_UPSTREAM=1 to the plugin | 16:29 |
| cr1901 | because BUILD_UPSTREAM=0 assumes yosys installs frontend/verilog/verilog_frontend.h to the dest, and my copy doesn't | 16:30 |
| sf-slack | <tgorochowik> yeah, the build process is quite simple, but the important thing are the versions of the submodules | 16:30 |
| cr1901 | (and forcing it to be installed gets errors like "the class member 'is_packed' isn't found" | 16:30 |
| sf-slack | <mkurc> cr1901: Could you explain how you are running the "dram_test_64x1d_bin" test? Where does it come from? | 16:39 |
| cr1901 | I built symbiflow by running "make env" with the following environment variables set (h/o): | 16:41 |
| cr1901 | http://gopher.wdj-consulting.com:70/paste/1d361514-1404-47e6-9e45-e844e1bbcb10.txt | 16:41 |
| cr1901 | make CMAKE_FLAGS="-GNinja \ | 16:42 |
| cr1901 | -DTRELLIS_LIBDIR=/home/william/Projects/FPGA/prjtrellis/libtrellis \ | 16:42 |
| cr1901 | -DTRELLIS_DATADIR=/home/william/Projects/FPGA/prjtrellis \ | 16:42 |
| cr1901 | -DYOSYS_DATADIR=/home/william/Projects/FPGA/yosys/share" env | 16:42 |
| cr1901 | Yosys 0.11+47 (git sha1 113c94384, sccache gcc 9.3.0-17ubuntu1~20.04 -fPIC -Os) | 16:42 |
| cr1901 | After conda is finished being set up via make env, I cd to my build/ directory and run | 16:43 |
| cr1901 | ninja -j4 dram_test_64x1d_bit (sic... sorry I typo'd) | 16:44 |
| cr1901 | Eventually, after most of the build runs successfully, yosys will die with a segfault: http://gopher.wdj-consulting.com:70/paste/e5174237-0957-4424-b3d3-5b203262cba6.txt | 16:45 |
| sf-slack | <mkurc> cr1901: So you basically running the test from symbiflow-arch-defs but you are "injecting" a locally build Yosys binary. | 16:45 |
| sf-slack | <mkurc> I don't think that the way you run that actually uses surelog/UHDM | 16:45 |
| cr1901 | mkurc: Correct. I may need to do dev against my machxo2 yosys branch | 16:45 |
| cr1901 | AHhh I see, well... still a bug :P? | 16:46 |
| sf-slack | <mkurc> Maybe it is a problem with the yosys revision being incompatible with symbiflow-arch-defs | 16:47 |
| sf-slack | <mkurc> The revision used on master (conda pkg) is yosys=0.11_7_g4bf8deacb=20211005_122659_py37 | 16:47 |
| cr1901 | Rebuilding/reconf'ing now | 17:00 |
| cr1901 | No, that revision of yosys still fails... what version of yosys-plugins are used? | 17:03 |
