[dvsim] Question: Where to find a handbook including all the keywords available in hjson and core file about opentitan HOT 1 CLOSED

Hey @desorya,

The .core files are Fusesoc core files, which have a complete API documentation page here.

The .hjson files used throughout OpenTitan have a number of different uses, so there isn't one schema that covers everything. However, I can give you a few examples:

• Files defining Comportable IP HWIP blocks (e.g. hw/ip/i2c/data/i2c.hjson) have keys defined in the Comportatbility Specification (e.g. here), as well as register definition fields from the reggen/regtool tooling docs.
• .hjson files for DV simulations have some documentation available. Files defining testplans (e.g. hw/ip/i2c/data/i2c_testplan.hjson) are documented, but the configuration files that drive our simulation runner dvsim (e.g. hw/ip/i2c/dv/i2c_sim_cfg.hjson) are not.
• Files defining top-level assemblies (e.g. hw/top_earlgrey/data/top_earlgrey.hjson) are ingested by the topgen tool, but the schema here is not formally documented afaik.

This is something we should improve in the future. In the meantime, I suggest trying to find keywords using the search on the documentation site (click the magnifying glass in the topbar or use the keyboard shortcut s). Otherwise, grepping the codebase while limiting your search to python files may bring up some code comments around where a particular keyword is parsed.

I hope that was helpful. If so, would you mind closing the issue? Thanks

from opentitan.
