VHDL Models of Hardware

VHDL supports the three necessary facets for system modeling. Behavior is necessary to describe how system components respond to stimuli. Structure describes how the various subcomponents are connected to each other. The timing model provides a framework so that system events can occur in the correct order.

VHDL makes no assumptions about the underlying hardware. While the designer can add as many specifics as needed, VHDL will also operate with a general description only.
