VHDL-LS is one of the most popular free and open-source Language Servers for VHDL as measured by GitHub stars. With features such as syntax and type checking, code navigation, completion and many more, it boosts developers abilities to write VHDL code.

This talk dives deeper into the basics of language servers, presents the current state of VHDL-LS and demonstrates its capabilities such as semantic analysis, diagnostics, code navigation and editor integration. We will discuss how these features improve productivity and code quality for FPGA developers. Finally, we outline future ambitions for VHDL-LS, including the development of a language API and a broader ecosystem of VHDL tooling wit the aim of modernizing VHDL development, enabling new forms of automation and analysis.
