Integrated Circuit Design

Simulation versus Emulation

　　Simulation: Simulation is the imitation of some real thing, state of affairs, or process.

　　　　　　Flight Simulator: 模拟飞行操作的过程，反映各个过程时的系统状态。

　　Emulation: An emulator in computing duplicates (provides an emulation of) the functions of one system using a different system, so that the second system behaves like (and appears to be) the first system.

　　　　　　If Flight Emulator Exists: 那么Flight Emulator应该像正真的Flight，将你带到目的地。

　　　　　　对于系统A，存在输入X，输出Y。那么在系统B上实现的A的Emulator：A'。A'同样能处理输入X，输出Y。

VHDL = VHSIC hardware description language, where VHSIC was a 1980s U.S. government program to develop very-high-speed integrated circuits

Verilog

SystemVerilog = SystemVerilog is a superset of Verilog-2005

IC Design

　　　　　　　　　　　　Fig. Traditional ASIC Design Flow

ASIC = application-specific integrated circuit

　　The various cost function for an ASIC chip could be "Area, Timing, Power" Targets.

RTL = Register Transfer Level
