What is VHDL


VHSIC Hardware Description Language (VHDL) is language for designing digital system, it is use to program FPGA,it is parallel programming language.The three type of modeling structural, data flow and behavioral. 


VHDL is developed 1983 for department of Defense (DoD) under the Very High Speed Integrated Circuit (VHSIC) program.
