For example, in aircraft manufacturing process, from design, performance testing and characterization until the flight simulation, may be related to EDA technology. This article refers to the EDA technology, mainly for electronic circuit design, PCB design and IC design. EDA design can be divided into system-level, circuit level and physical implementation level. Second, the design methods and techniques Method (1) front-end design (RTL-level description of system modeling) back-end design (FPGAASIC) System Modeling (2) IP reuse
 (3) front-end design (4) System Description: create a system of mathematical models. (5) Description: Describes the behavior of the system or between the various sub-module data flow diagram. (6) Logic Design: The functional structure of the system, usually text, schematics, logic diagrams, Boolean expressions to represent the design results.
 (7) simulation: functional simulation and timing simulation, including the main function of the correctness of the verification system and timing characteristics. Skill (1) lock in the input circuit KEYB 0ARD.VHD frequency for various signal / signal sequence design is unique. The design, using a variety of free counters to generate the desired frequency, that is, first create an N-bit counter, N the size of the circuit according to the needs of the decision. The higher the value of N, the number of circuits can be in addition to the more frequent, so you get greater frequency in order to provide a variety of different frequency clock signals. If the input clock CLK, N-bit counter output Q [N-1, 0], then Q (0) 2 for the CLK frequency pulse signal, Q (1) of CLK is divided by 4 pulse signal, Q ( 2) CLK divided by 8 pulse signal, ... ... Q (N-1) as the CLK frequency of 2N pulses; Q (5 DOWNT04) is achieved by a pulse waveform sequence, its value is in accordance with 00-01-10 -11-00-01 cyclical changes, and its frequency of change in frequency of CLK 25, which is divided by 32. We use the above rules we need to get the frequency of the signal or signal sequence.
