Integrate IC618 with FreePDK45

xiangumass

Hello, I am setting up tools for a couruse now. I have followed steps to set up IC618 base and FreePDK45. The OS is Rocky Linux 8.6.  However, I have no way to make the layout display work. I can only see cross bars as shown below. I know FreePDK45 is pycell and I also installed pycell studio. The information shows :

*WARNING* (DB-220706): The Pcell plug-in for super master 'NCSU_TechLib_FreePDK45/nmos_vtl/layout' could not be loaded: Cannot find IPcell 'cnDloPcell': Pcell evaluator 'cnDloPcell' not found: Shared Library Not Found: Error loading library 'libcnDloPcell.so'. /opt/cadence/ic618/tools/lib/64bit/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /home/xiang/PyCellStudio_installer_OnePackage_S-2021.09/temp/linux64/lib/python-26/libcnUtilPy26.so)...

My understanding is that the pycell is not compatible with the GLIBCXX used by IC618. Could you please let me know if there is any solution to this or if my understanding is correct? Thank you very much for your help.
