Description

Currently dvsim cannot parse reports generated by MeridianCDC. Even for successful runs, dvsim exits with an error. The user can then use iDebug to analyze the results with a GUI. Once CDC for Earlgrey is clean, we may want to add CDC checks to nightly regressions, for which we would need dvsim to parse the reports and produce results (in HTML and JSON, as usual).

Before #24209, there was a report parser for VerixCDC, which could be used as a starting point for the report parser for MeridianCDC.

Research direction

Start by locating the dvsim report-parsing path and reviewing the former VerixCDC parser mentioned as the starting point before #24209. Compare it with MeridianCDC reports, then verify that successful runs produce the usual HTML and JSON results without errors.
