Software Design Based on PLD High-Speed Data Acquisition System

Data collection in the important position of modern industrial production and scientific research is increasingly outstanding, as well as the real-time collection, real-time transmission and real-time processing of high speed data acquisition requirements are constantly improve. In addition, for different occasions, the data acquisition system of data sampling parameters are different. PLD as a universal integrated circuit, its logic function according to user's programming on the device, this paper introduces the high-speed data acquisition system based on PLD, mainly expounds the software design of the system, this paper introduces a simple PLD system, using FPGA as the data acquisition chip, the main measure the infrared remote control code acquisition, based on EDA technology to design a core, using DMA access to data, to achieve high-speed system requirements.

Study on Mechanical and Electrical Automation with System Design of Frequency Meter Based on EDA Technology

Frequency meter as a kind of electronic measuring instruments, have been widely applied in the field of Mechanical and Electrical automation. The design of a frequency meter based on EDA technology, is implemented in EDA software platform of Quartus II, using hardware description language (HDL) editor can also be seasonal schematic, design, system hardware circuit compiler, simulation, system is divided into five modules: frequency module, control module, counting module, range switching module and display module, the hardware design requires a download chip EPM7128S and input and output circuit.

The Design of Governing System of DC Motor Based on EDA Technology

Applying EDA technology, the dc speed governing system was designed, which produces digital signal of PWM waveform. These produced signals can be directly added to the dc machines, by changing the duty ratio of impulse wave, to realize speed regulation, not needing D/A transformation. With a high reliability and strong antijamming capability, this design is used widely. The simulation results of MAX + plus II software indicates that the desired effect is achieved for this design.

The Study of Electronic Design Public Elective Courses Teaching in Colleges and Universities by Tina Pro

With the continuous development of EDA technology, its advantage in electronic courses teaching in college and universities is becoming increasingly prominent. The introduction of Tina Pro technology into the teaching of Electronic Design public elective courses in colleges and universities can improve the non electronic students’ interesting in learning Electronic Design, let the Electronic Design get a more effective and wider promotion, and improve the students’ innovation ability and manipulative ability.

The Design of Electronic Code Lock

In this paper, by using EDA technology, Quartus II6.0 working platform and VHDL hardware description language, an electronic code lock based on the programmable gate array FPGA is designed with a top-down design.

An Auto-Switched Chaos System

In order to generate complex chaotic attractor, an atuo-switched chaotic system which consists of two subsystems is constructed. The switched chaotic system can change its behavior automatically from one to another via a data selector. The system is also implemented based on FPGA by EDA Technology, and the experiments shows a good agree with simulation.

Application of EDA technology and µClinux operating system in the earthquake precursor instruments

Using Altera’s Quartus II, Nios II IDE and Sopc Builder development tools, the proton precession magnetometer principle host hardware platform is designed in a cyclone II series FPGA chip (EP2C35). The proton precession magnetometer principle host core circuit’s single-chip system-logic design is achieved by building and configuring the Nios II soft-core processor, developing the IO interface and sensor control circuits, programming some hardware units’ VHDL code, for example the equal precision cymometer and the DPLL. Through researching the embedded operating system configuration technology and building the NIOS II soft-core processor’s µClinux cross-compile environment, the µClinux system is transplanted to the NIOS II environment. Another important task is writing the device drivers’ and user programs’ code. Through these work, the design realize the host function and achieve the expected target.

Flare mitigation strategies in extreme ultraviolet lithography

This study investigates various approaches to flare mitigation in EUVL. We evaluate the effectiveness of rule-based correction by defining a design where the critical dimension uniformity is used as a measure of the quality of the correction. We also describe the outcome of a model-based correction and the limits of this approach. Finally, we discuss the calculation of accurate full-chip flare maps which are required to implement a rule-based solution. Our results clearly indicate that it is possible to implement an effective flare variation compensation using rule-base correction with current EDA technology, provided that highly accurate full-chip flare maps having the required resolution are available.
