Conventionally, an FPGA-based design is often described by hardware description language (HDL) such as Verilog or VHDL. The design is specified at register-transfer level (RTL) by registers and combinational logics between these registers. It is a low-level abstraction and designers must appropriat...
For example, it is possible to describe a processor architecture using VHDL or Verilog, and to synthesize the design description using a set of design synthesis constraints into a logic description that can then be targeted to a specific FPGA device (design implementation, "place and route"). ...
