| Veera | Hi | 07:02 |
|---|---|---|
| Veera | I am trying to install symbiflow without conda | 07:02 |
| Veera | I used vtr version 8.0.0 | 07:03 |
| Veera | While compiling artix7_100t it fails with --allow_dangling_combinational_nodes error | 07:03 |
| Veera | Can you guys tell which vtr git commit to use; what does conda litex-hub vtr git commit uses | 07:05 |
| Veera | linux-64/vtr-optimized-8.0.0_4673_g0010a7374-20211005_122659.tar.bz2 | 07:06 |
| Veera | what does g0010a7374 in it stand for? | 07:06 |
| Veera | I checked git log; it does not appears there in any commit | 07:07 |
| Veera | acomodi: need help | 07:24 |
| sf-slack | <tahmed> Hello I am Talha Ahmed, an Undergraduate Software Engineering Student.

| kgugala | @Veera the `g0010a7374` is a commit hash - `g` means it's git and later you have a hash | 07:54 |
| kgugala | this particular one points to https://github.com/verilog-to-routing/vtr-verilog-to-routing/commit/0010a7374e17b6d81dac97fd4c9757b23ff0eea0 | 07:54 |
| Veera | kgugala: thanks | 07:55 |

| Veera | acomodi: I am trying to install symbiflow without conda | 08:20 |
| Veera | acomodi: which git version of yosys, vtr I should use for latest symbiflow-arch-def | 08:20 |
| sf-slack | <acomodi> Hi @tahmed, I have tried to reproduce the issue locally, but couldn't get the error and the flow continued pass the synthesis step. Can you please verify your packages are up-to-date? | 08:21 |
| Veera | acomodi: I was able to successfully install symbiflow-arch-defs with an old git commit | 08:21 |
| acomodi | Veera, at the moment the tested versions of yosys and vtr can be taken from the environment.yml files | 08:23 |
| acomodi | e.g. litex-hub::vtr-optimized=8.0.0_4118_g06317d042=20210813_070938 -> the commit for VTR in this case is `06317d042` | 08:23 |
| Veera | and for yosys | 08:24 |
| acomodi | 539d4ee9 | 08:24 |
| acomodi | you can check those from here | 08:24 |
| acomodi | https://github.com/SymbiFlow/symbiflow-examples/blob/master/xc7/environment.yml | 08:24 |
| Veera | oh symbiflow-arch-defs have removed the specific versions | 08:25 |
| acomodi | yeah, that because there is a conda locking bot, so that the newer versions get updated regularly, and, once verified, a conda lock file is generated | 08:27 |
| acomodi | https://github.com/SymbiFlow/symbiflow-arch-defs/blob/master/conda_lock.yml | 08:27 |
| Veera | acomodi: thanks for explaining | 08:29 |

| kgugala | @tahmed this seems to be an issue with xdc plugin (https://github.com/SymbiFlow/yosys-symbiflow-plugins/blob/master/xdc-plugin/xdc.cc) | 08:50 |

| Veera | acomodi: in symbiflow-examples TARGET="arty_35" make -C counter_test | 09:15 |
| Veera | acomodi: does not works with default symbiflow-arch-defs artix7 target | 09:15 |
| Veera | acomodi: there is no configuration oir installation for arty_35; only for arty_50 | 09:16 |
| acomodi | Veera: the a35 and a50 devices have the same fabric internally, so only the a50 is needed. What error are you getting? | 09:41 |
| Veera | I do not have pinmaps for a35 | 09:44 |
| acomodi | Veera: you mean the pinmap.csv in the installation files? in that case those are available. | 09:56 |
| acomodi | for two parts actually, xc7a35tcpg236-1 and xc7a35tcsg324-1 | 09:57 |
| Veera | acomodi: i will try to manage | 09:57 |
| Veera | acomodi: am quiting for now | 09:58 |
