Hey @joamatab, do you know of a comprehensive syntax specification for these files? Regards JD

[das-dias]

Is the parser for SPICE already implemented within gdsfactory? If not I think a literal conversion between the two formats using a parser is possible and advised I think. Since YAML is a data-driven language supporting only assignment of variables (much like SPICE is), a literal conversion would be preferred, to keep the parsing between the two easy! This way YAML becomes just SPICE with tabs and newlines.

We have a Layout to SPICE using klayout

i added a proof of concept here
