Error encountered with FASM, antlr_to_tuple, running xc7 counter example #108

tcal-x · 2020-12-20T06:38:23Z

After a clean install of xc7 tools according to the symbiflow-examples instructions, I get to the first example to run (https://symbiflow-examples.readthedocs.io/en/latest/building-examples.html):

TARGET="arty_35" make -C counter_test

and this runs Symbiflow but ends with this error:

The ANTLR parser has some dependencies outside of PyPI, which is why the fallback parser is necessary.

Could you please post the results of:

sudo apt install cmake default-jre-headless uuid-dev
https://github.com/SymbiFlow/fasm.git
cd fasm
make build

Thanks.

I also run into the same issue with antlr_to_tuple, so it's not an isolated issue.

mithro · 2020-12-20T22:15:07Z

Any idea why this isn't appearing in the CI?

HackerFoo · 2020-12-20T22:16:38Z

You'll definitely need cmake. Once you have a working cmake, pip install -v git+https://github.com/SymbiFlow/fasm.git should install the Cython requirement automatically.

You'll definitely need cmake.

I do have cmake -- as a Python module.

$ which cmake
/home/tim/.local/bin/cmake
$ pip list | grep cmake
cmake                  3.16.3
$ pip3 list | grep cmake
cmake                  3.16.3

In other instructions that asked me to sudo apt install cmake <other packages>, I'd just skip the cmake and it would be ok.

But, let me get to the bottom of why the apt install of cmake doesn't work for me.

HackerFoo · 2020-12-20T22:33:53Z

@andrewb1999 I can see that cmake failed, but unfortunately not why. This should print the output from cmake:

git clone https://github.com/SymbiFlow/fasm.git
cd fasm
make build

andrewb1999 · 2020-12-20T22:41:01Z

@HackerFoo Looks like it's not getting the cython dependency correctly (same issue as @tcal-x )

if [ -e env/bin/activate ]; then . env/bin/activate; fi; python setup.py build

mithro · 2020-12-20T23:15:23Z

python setup.py won't install dependencies, all dependencies must be preinstalled. You probably want something like pip install . if you want packages to be installed.

tcal-x · 2020-12-21T01:17:36Z

My problems installing cmake with apt seem to have originated from having "kitware" as a source. After I removed that, I was able to install cmake. I'll try the install again and see if it goes any better.

tcal-x · 2020-12-21T05:23:47Z

I ran this to take care of the Cython requirement:

pip3 install cython

Then I followed the instructions on the page https://github.com/symbiflow/fasm#build-instructions including the sudo apt install ... libantlr4-runtime-dev and the git submodule update --init, and after that, the make build succeeded. I did this install (also from the page mentioned earlier) while still in the conda environment ("xc7"):

pip install . --install-option="--antlr-runtime=shared" --no-use-pep517

and then the original SymbiFlow build of the counter example worked.

HackerFoo · 2021-01-05T19:36:40Z

It looks like the install instructions specify an older version of the toolchain. Should this be automatically updated somehow? There are "latest" text files that specify the latest URL: https://github.com/litex-hub/litex-conda-eda/blob/master/pnr/vtr-optimized/build.sh#L34-L53

I've assigned this to myself to check if the issue has been resolved.

tcal-x · 2021-01-20T08:26:19Z

Nothing has changed; I still see the original error.

It seems we either need to address #115, or, as a band-aid, manually update the versions.

tcal-x · 2021-01-24T07:47:09Z

Correction: the final warning from fasm looks like failure, but in fact a bitstream is produced, and it works correctly on the Arty 35T board (counter_test example).

I had noticed in Quicklogic guides for QORC, they specifically describe this warning and tell the user that it's ok.

This is the warning:

@tcal-x - Yes, that is a warning but means the command will be much slower. We should make sure the fast path is what most people get by default.

jgoeders · 2021-02-01T22:00:44Z

I was also running into this. Although there is a fallback, the warning would be printed to my fasm file, which would then break things:

Please install all dependencies and reinstall with:
  pip uninstall
  pip install -v fasm

I followed @HackerFoo 's instructions and did the following:

git clone https://github.com/SymbiFlow/fasm.git
cd fasm
make build

After which I realized I needed to:

Make python point to python3. (I'm using Ubuntu 20 where python points to nothing by default. I just added alias python=python3 to my ~/.bashrc).
sudo apt install python3-venv

This fixed thing for me and the fasm.parser ImportError is gone. Hope this helps others.

Couple things. First, we have an PyPi account setup, so if someone adds a PyPi publish to https://github.com/symbiflow/fasm, this issue becomes must easier to solve!

Second, there are instructions in https://github.com/SymbiFlow/fasm/blob/master/README.md on how to build FASM with the ANTLR parser.

Issue with more details: f4pga/f4pga-arch-defs#1846

Ok, I think it is resolved. I was able to generate the bitstream without the fallback warning:

Incr Criticality updates 0 in 0 sec
Full Criticality updates 1 in 4.2928e-05 sec
Writing Implementation FASM: top.fasm
The entire flow of VPR took 19.0512 seconds.
FASM extra: top_fasm_extra.fasm
writing final fasm
cd build/arty_35 && symbiflow_write_bitstream -d artix7 -f top.fasm -p xc7a35tcsg324-1 -b top.bit
Writing bitstream ...
