Learning the importance of VHDL

In the past decade, the rapid development of ultra-large scale integrated circuits and software technologies has made it possible to integrate digital systems into an integrated circuit, altera, Xilinx, AMD, and other companies have launched excellent CPLD and FPGA products, and are equipped with design and download software for these products, in addition to the graphic design of digital systems, these software also supports the Design of Multiple digital system design languages, making it easier to design digital systems. It can be said that the design of digital electronic technology has entered a new era.

Today, small-scale digital integrated circuits will be eliminated. As an electrical graduates, we should be familiar with the design of VHDL, CPLD, and FPGA Devices, YAN Shi Professor's new teaching materials have also added the content of the VHDL language. It can be seen that the use of VHDL to integrate the digital system into an integrated circuit is now an important part of digital electronic technology teaching.

To enable students to learn VHDL, teachers should first learn it by themselves, but learning the VHDL language requires a language environment that provides file input, logical synthesis, compilation, and simulation, I would like to recommend a language environment-the MAX + plus ⅱ software of Altera, which can be used to input digital circuit design files in graphics, text, and waveforms, the text format supports the VHDL, ahdl, and OpenGL Hardware Description Languages. The software has multiple component libraries (full series of TTL, macro functions, and giant function libraries ), you can specify two Altera devices, device pins, and logic Integration Methods of the max7000 and 10k10 series. After compilation, the downloaded files can be programmed using programming hardware, the software can locate errors and check design rules, making the design easier and easier.

The software supports both versions of VHDL, 87 and 93, and has all the support libraries of VHDL.

This software can help you learn and use the CPLD product of Altera Corporation. The CPLD product of Altera Corporation represents the development direction of PLD, and shows the level of FPGA products of Xilinx Corporation, in particular, the company's ahdl language makes it easier to design digital systems.

The software can complete the entire process of input design files, specified devices and pins, compilation, simulation and download (hardware required. If no hardware is available, download is not available, and other steps can be performed. It can be seen that it is a very good software for teaching.

The software is supported by the Windows platform, provides refined menus, and is easy to use. It is really an environment for learning the VHDL language.
