Verilog – Combinational Logic Verilog for Synthesis. vlg • Icarus Verilog is a compiler called iverilog – Compiler output can be vvp fpga vhdl – A vvp file is executed by vvp, which is the Icarus Verilog runtime engine. DIGITAL SYSTEMS DESIGN USING VERILOG integrates coverage of logic design principles, Verilog as a hardware design language, and FPGA implementation to help electrical and computer engineering students master the process of designing and testing new hardware configurations. Test results 4. One of the major disadvantages of the Braun's multiplier is that the number of components required increases quadratically with the number of bits.
