Unable to write coverage via UCIS API (Cadence)

[penguali]

I am trying to write out the coverage from a testbench written in cocotb using this line:

vsc.write_coverage_db('cov.db', fmt='libucis', libucis='libucis.so')

However, I am getting an AttributeError from ucis:

vsc.write_coverage_db('cov.db', fmt='libucis', libucis='libucis.so')
File "/path/to/venv/lib/python3.12/site-packages/vsc/__init__.py", line 113, in write_coverage_db
                                                            LibFactory.load_ucis_library(libucis)
File "/path/to/venv/lib/python3.12/site-packages/ucis/lib/LibFactory.py", line 42, in load_ucis_library
                                                            libucis.load_ucis_library(lib)
File "/path/to/venv/lib/python3.12/site-packages/ucis/lib/libucis.py", line 146, in load_ucis_library
                                                            func = proto((f, _lib), attr)
                                                                   ^^^^^^^^^^^^^^^^^^^^^^
AttributeError: /path/to/libucis.so: undefined symbol: ucis_CreateHistoryNode

Any idea what could be going wrong here? Is there anything that I must configure prior to writing the coverage data?
I am able to write the coverage in the XML format though.

Thanks in advance.

I recommend checking in with your Cadence Application Engineer. Different vendors have different preferred approaches to bringing in coverage data -- and these may even change over time. I seem to recall that there was a utility for importing coverage data. But, again, this may have changed.

Ok thanks for the reply. I will keep this issue open for a while until I find a way to import the coverage with Cadence.
If I find any solution, I will post it here. If not then I will just close it :)
