What are the main features of VHDL?

(3) VHDL has good readability, is close to high-level language, and is easy to understand.

(4) The system design has nothing to do with the hardware structure, which facilitates the conversion of the process, and does not make the description obsolete due to process changes.

(6) For a certain design completed with VHDL, the EDA tool can be used for logic synthesis and optimization, and the VHDL description can be automatically converted into a gate-level netlist file.

(7) The design is flexible, easy to modify, and also facilitates the exchange, preservation and reuse of design results, and the product development speed is fast and the cost is low.
