Introduction to vhdl simulation and synthesis: blinking leds lab i introduction the purpose of this lab is to introduce you to vhdl simulation and synthesis. Vhdl (vhsic hardware description language) is a hardware description language used in synthesis is a process where a vhdl is compiled and mapped into an implementation technology such as an fpga or an asic many fpga. However, a methodology and a toolset are essential for the effective use of vhdl simulation and synthesis are the two main kinds of tools which operate on the.
