Flow error that dc is unsupported for job runtime extraction

[gzyangcs]

I ran a dc synthesis flow but dvsim gives report below.
The command i ran is "./util/dvsim/dvsim.py -t dc hw/top_earlgrey/syn/chip_earlgrey_asic_syn_cfg.hjson --purge --local" , which found at readme "OpenTitan Synthesis Flow".

I saw the issue #16295 and tried the fixes proposed in #16501 , but it's not work for me.

[sriyerg]

The dc is unsupported for job runtime extraction is a benign warning that can be ignored. The real issue appears to be elsewhere. Perhaps there is a syntax error in one of your fusesoc core files?

Please see these warnings:

WARNING: Parse error. Ignoring file /home/guozhiyang/work/opentitan/bazel-opentitan/fusesoc/tests/capi2_cores/misc/empty.core: Missing 'name' parameter
WARNING: Parse error. Ignoring file /home/guozhiyang/work/opentitan/fusesoc/tests/capi2_cores/misc/empty.core: Missing 'name' parameter

And this error:
