First of all to know what you are doing? Digital circuit (fpga/asic) design is the realization of the logic circuit, so that is too narrow, because there a lot of asic simulation, huh . We only discuss digital circuit design here. Is actually how we use the logic the classroom to use the schematic diagram (very few people use this pull), or hardware description language (Verilog/VHDL) to achieve, perhaps you think this is too simple, in fact, complex design That is, with the logic gate to build up. When you learn the logic of the circuit may be for the Karata, flip-flop state of the formula and feel confused, but in fact there is one thing can be assured that the actual design only requires you to understand the interface timing and function can be, and not so complicated Down the formula, as long as you can use the language to express the logical relationship can be clear, the specific logical relationship with what the door to take, you can not care, comprehensive tools (syn
