Error while running demo.py

[KushagraGupta02]

Hi,

Could you please let me know the possible reason for this error while running demo.py - I have followed all instructions on the README and installed yosys, iverilog on the PATH as well:

146 is 1 100% of the time
148 is 0 100% of the time

Yup the demo is broken and docs are a bit outdated. I'll actually be working this week to fix some bugs and improve the docs. Will comment here when that's done.

Hi @KushagraGupta02,

the repo has been updated and so the instructions to run the demo. Please, feel free to try it again and let us know if it is working for you.

Hi @jorge-castro-godinez @zkwinkle

Sorry for the delay in my response:
I tried to run it again and the issue is similar to #6: output_approx.txt is not in the directory

Traceback (most recent call last):
File "/home/user/AxLS2/AxLS/demo.py", line 114, in
error = our_circuit.simulate_and_compute_error(TB, EXACT_RESULT, APPROX_RESULT, "med")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

file = open(filename, 'r')
^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'ALS-benchmark-circuits/BK_16b/output_approx.txt'

Could you please help debug this?
Thanks a lot!

Hello, that's OK we're also not the quickest at replying.

Could you provide the steps to replicate your issue? Also please make sure you've downloaded the latest changes.

I just attempted cloning a fresh version of this repository and was able to execute demo.py succesfully.

I ran the following commands:

(I git clone through ssh)

git clone git@github.com:ECASLab/AxLS.git 
cd AxLS
git clone git@github.com:ECASLab/ALS-benchmark-circuits.git
python demo.py

and successfully executed the demo.
