Introduction:

High-Level Synthesis (HLS) has emerged as a powerful technique in semiconductor design, enabling designers to efficiently transform abstract behavioral descriptions into optimized hardware implementations. VHDL (Very High-Speed Integrated Circuit Hardware Description Language) serves as a key language for HLS, offering numerous benefits and opportunities. This blog post explores the advantages and applications of using VHDL in the context of HLS for semiconductor design.
