verilog: Verilog (A Verilog simulation and synthesis tool) verilog: verilog: Icarus Verilog is a Verilog simulation and synthesis tool. It operates verilog: as a compiler, compiling source code writen in Verilog (IEEE-1364) verilog: into some target format. For batch simulation, the compiler can verilog: generate an intermediate form called vvp assembly. verilog: verilog: verilog: verilog: verilog:
