Application of VHDL in EDA

The very high integrated circuit HW description language (VHDL), its basic features and one of its powerful simulation tool, Active VHDL, are introduced. With an example, The important role played by VHDL in the simulative test of digital circuit design is described. The synthesis is needed to complete the design after simulation. A real chip design by EDA with VHDL simulation and synthesis tools is successfully fulfilled and satisfied result is achieved.
