| sf-slack | <ajinkyaraghuwanshi> I am trying to run the test model in the SymbiFlow-arch-defs, I created a test model ,ran this code and got this output: " make -f CMakeLists.txt CMakeLists.txt:1: *** missing separator. Stop.". Now I am not able to understand what was the supposed output as I am getting the same output for all the test files in it. | 09:22 |
| sf-slack | <ajinkyaraghuwanshi> I am getting this same output for all the make files in SymbiFlow-arch-defs | 09:28 |
| sf-slack | <ajinkyaraghuwanshi> I am also not able to build the pre-existing models after making the env, in the getting started manual of the SymbiFlow-arch-defs | 09:30 |
| sf-slack | <ajinkyaraghuwanshi> Can anybody help? | 09:31 |
| sf-slack | <fdarling> @ajinkyaraghuwanshi maybe I am misinterpreting what you've written, but you should't run `make` directly on a CMakeLists.txt file, but rather you should run `cmake` on it. You typically create a `build` subdirectory, and run `cmake ..` which pulls in the `CMakeLists.txt` file from the parent directory. | 12:40 |
| sf-slack | <ajinkyaraghuwanshi> yes that I misspelled but the problem that none of my make files are working | 12:47 |
| sf-slack | <ajinkyaraghuwanshi> basically after the make env , none of the build and other make files are working, I have also tried to clean and repeated the process which took hours but I am still getting some errors | 12:52 |
| sf-slack | <ajinkyaraghuwanshi> | 12:53 |
| sf-slack | <fdarling> @ajinkyaraghuwanshi walk me through what you're trying to do, I just cloned https://github.com/SymbiFlow/symbiflow-arch-defs.git myself so I can test whatever it may be | 12:59 |
| tpb | <https://x0.no/4uwwk> (at github.com) | 13:00 |
| sf-slack | <ajinkyaraghuwanshi> I am trying to make a test program in the system to be ran by yosys | 13:02 |
| sf-slack | <fdarling> is your goal to set up Yosys for a particular family of FPGA, or is it to test something specifically within that git repository? | 13:03 |
| sf-slack | <ajinkyaraghuwanshi> I want to test the in the repo itself later it will be based for artix7 board | 13:05 |
| sf-slack | <fdarling> all right, so you are using that same repository that I linked you to, right? | 13:07 |
| sf-slack | <fdarling> I am confused because in that log_inst.txt you posted, you run `make -f Makefile` (equivalent of just `make`) first, and then you do `make all_demos` before running `make env`, even though the README.md file says to run `make env` first | 13:09 |
| sf-slack | <ajinkyaraghuwanshi> Yes | 13:11 |
| sf-slack | <ajinkyaraghuwanshi> I have followed the same steps before also | 13:12 |
| sf-slack | <fdarling> for me `make env` runs a *lot* of stuff, downloading git repositories, installing python pip dependencies, etc. | 13:12 |
| sf-slack | <ajinkyaraghuwanshi> here I was trying to again run them so it looks as if I am trying to run all_demos before env | 13:13 |
| sf-slack | <ajinkyaraghuwanshi> yes it is same for me too | 13:13 |

| sf-slack | <ajinkyaraghuwanshi> no | 13:17 |
| sf-slack | <ajinkyaraghuwanshi> I checked it is still 3.3GB free for that drive | 13:18 |
| sf-slack | <fdarling> "sqlite3.OperationalError: database or disk is full" that is concerning | 13:18 |
| sf-slack | <ajinkyaraghuwanshi> yes I thought too but when I checked it showed 3.3GB space avaiable | 13:18 |
| sf-slack | <fdarling> would you please show me the output of `df -h` ? | 13:19 |
| sf-slack | <ajinkyaraghuwanshi> ok it will take 2 min | 13:19 |
| sf-slack | <ajinkyaraghuwanshi> | 13:23 |
| sf-slack | <ajinkyaraghuwanshi> | 13:23 |
| sf-slack | <fdarling> you say that there was free space, but if you notice it says "make[2]: *** Deleting file 'xc/xc7/archs/zynq7_z020/devices/xc7z020-virt/channels.db'" after the error message, so it may have cleaned up after itself and hidden the fact that it was using 100% disk space | 13:24 |
| sf-slack | <fdarling> I assume you're operating with a VirtualBox VM. If so, I suggest shutting it down and growing the virtual disk size to be larger, then use a "live CD" with `gparted` to resize/move the partitions to take up the newly available space | 13:30 |
| sf-slack | <fdarling> so far the symbiflow-arch-defs directory on my system is taking up 6.1GB, but it seems a long way off from being finished | 13:31 |
| sf-slack | <fdarling> I'll let it finish and report how much space it took up | 13:31 |
| sf-slack | <ajinkyaraghuwanshi> Actually I am using ubuntu, in my dual boot system | 13:34 |
| sf-slack | <ajinkyaraghuwanshi> so increasing the space is a problem | 13:34 |
| sf-slack | <fdarling> I am running Xubuntu 20.04 for the record | 13:36 |
| sf-slack | <ajinkyaraghuwanshi> I am working on the project-XRAY and I wanted to know that the git prjxray and the folder in the symbiflow-arch-defs, are they same? | 13:37 |
| sf-slack | <ajinkyaraghuwanshi> So, did you complete the installation? | 14:28 |
| sf-slack | <ajinkyaraghuwanshi> So was the installation complete? | 14:33 |

| sf-slack | <nelson> I saw above some comments yesterday or the day before regarding initialization of flip flops to either a 0 or 1 on power up with the tool flow, and I wanted to weigh in. We are seeing similar issues --- in the designs my student is running through the symbiflow-examples flow they have confirmed that if a Verilog signal is declared with an initializer as in: “reg[3:0] cnt = 0;” and that signal is the register for | 20:20 |
| sf-slack | a counter, then the counter will power up to 0000. But, if they just do: “reg[3:0] cnt;” the counter will power up to 1111. I don’t know if any standards document describes the required behavior. But, it is in contrast to other FPGA design tools I have used over many years with Xilinx FPGAs. I am not stating that I rely on this but just that it is different from anything else I have ever seen. I would be curious | 20:20 |
| sf-slack | regarding others’ thoughts on why this was chosen as the behavior for the tool flow (or if it wasn’t chosen and this is perhaps a bug). | 20:20 |
| tpb | <gatecat> I think this is probably happening because a synchronous set is being inferred for the flipflop. Older Xilinx FPGAs couldn't have the SR and init values set differently; so an async set means a default init of 1 if not overriden in Yosys, this reduces the code path differences between the different Xilinx families | 20:26 |
| tpb | <gatecat> Initialisation in synthesis isn't really defined at all (because it doesn't apply to ASICs); but it's certainly the case that in simulation an uninitialised register will initialise to x's | 20:27 |
| tpb | <gatecat> there's a whole host of behaviour in practice across different tooling, including in one case ignoring the initial value and always initialising flops to 0 | 20:27 |

| sf-slack | <fdarling> mine ultimately failed here: | 21:05 |
| sf-slack | <fdarling> ```$ du -hcs symbiflow-arch-defs/ 23Gsymbiflow-arch-defs/ 23Gtotal``` | 21:05 |
| sf-slack | <fdarling> so it did grow to quite a large size first | 21:05 |
| sf-slack | <fdarling> ```$ find -type f -name channels.db | xargs du -hcs 4.3G./build/xc/xc7/archs/artix7_100t/devices/xc7a100t-virt/channels.db 1.5G./build/xc/xc7/archs/artix7_100t/channels/xc7a100tfgg676-1/channels.db``` | 21:07 |
| sf-slack | <fdarling> those channels.db files can get pretty big, I seriously think it may have been the problem | 21:08 |
