Hi

I encountered an error when using the latest CoSA (both the master branch on github and the latest from pip3 seems to produce the same error message).

Here is the error message (on the AXI example):

~/case-studies/axi$ CoSA --problems problem.txt

I have CoSA installed in the virtual environment and the installed packages are:

bit-vector (0.39a0) coreir (2.0.19) CoSA (0.4) Cython (0.29.2) gmpy2 (2.0.8) hwtypes (1.0.13) Jinja2 (2.10) MarkupSafe (1.0) numpy (1.15.3) pip (9.0.1) pkg-resources (0.0.0) pyparsing (2.4.0) PySMT (0.8.0) pyverilog (1.1.2) setuptools (39.0.1) six (1.12.0) wheel (0.32.2) z3-solver (4.8.5.0)

I have Python 3.6.8 on Ubuntu 18.04

Please don't hesitate to tell me if there is any additional information that I can provide.

Hi,

That looks like a version issue with Yosys actually. There were some updates to the btor output of Yosys, so I updated CoSA accordingly. However, you’ll need to update your version of Yosys so they match. Let me know if that still doesn’t fix your issue!
