Set toolChain in .vscode/property.json, place the caret inside the device string and type a prefix or press Ctrl+Space.

Select family → chip → package → full part/speed grade. Intermediate selections reopen suggestions; longer prefixes skip directly to a matching stage. Suggestions use unsaved toolChain edits as well.

Toolchain	Bundled catalog
xilinx	4,131 real Vivado 2022.2 parts across 41 returned families/variants
efinity	360 parts from Efinity June 2024, covering Trion and Titanium; completion also accepts efinix

No local vendor installation is needed for suggestions. device remains free-form: requesting suggestions does not validate parts, save the document or rewrite other fields. Type newer parts manually when needed; actual support depends on the installed tool. Use efinity for hardware builds.
