Vies to answer the first design based on the EDA technology's intelligence competition
Abstract:
With a tool for answer devices, which has been widely used in all kinds of intelligence and knowledge contest occasions. But answer devices is used for lower frequency, and some production complex or low reliability, and reduced interest. As a unit, if the purchase is a answer devices. Although the economy can bear, each year the number is extremely small, because often the long-term storage causes to answer devices damage, the purchase of a mew one, the activities will be affected, so this answer devices is designed.
This design is eight roads Answer devices as the basic concept. From practical application, Complex programmable logic devices (CPLD) were used to design a competitive answer machine by use of EDA technique. The design of the Answer devices the use of Protel99 to complete the schematic diagram and the use of VHDL to complete the main control circuit design, including digital display circuit, countdown display and coding and decoding circuits. The ALTERA MAX+PLUS Ⅱsoftware tool was used for compilation emulation verification. The ALTERA EPF10K10LC84 was chosen in the hardware system to realize the system functions. The design of the competitive answer machine is easily expandable and provides good application results.
