DC plugin doesn't work

[exhaust-create]

I wanted to use DC to conduct synthesis but an error occurred.
I have done the actions below:

1. Add the dc plugin from the hammer-synopsys-plugins to the direction: hammer/synthesis(installed by pip);
2. Add class (SynopsysTool) to the file: hammer/vlsi/hammer-vlsi-impl.py.(installed by pip)

And the error showed:

File "/home/rfic/chipyard/.conda-env/lib/python3.10/site-packages/hammer/vlsi/hammer_vlsi_impl.py", line 2377, in load_tool
    tool: HammerTool = tool_class()
TypeError: Can't instantiate abstract class DC with abstract methods post_synth_sdc, version_number

How can I solve this problem?

Unfortunately, we haven't maintained the DC plugin since 2017 or so, hence it has been orphaned in hammer-synopsys-plugins repository when other Synopsys plugins have already been merged into this repository. Some years ago, @harikumar27399 updated the ICC plugin, but I'm not sure if he was able to use DC successfully then or not.

Are you willing to use Genus instead, or help update the DC plugin? If you'd like to try to update it, I can help you.

I don't have Genus package, so I turned to OpenRoad with ASAP7. I could produce hammer.d after running "make buildfile". However, when I ran synthesis using OpenRoad and asap7 with command "make syn tutorial=asap7-openroad", a new problem came out:  ERROR: Can't open ABC output file. What should I do for this problem? Or where could I find reference to overcome it? The details are shown in ucb-bar/chipyard#1936.
