Today, small-scale digital integrated circuits will be eliminated. As an electrical major graduate, one should be familiar with VHDL language and the design of CPLD and FPGA devices. The new textbook compiled by Professor Shi Yan also includes VHDL language. It can be seen that the integration of digital systems into integrated circuits by VHDL language is an important content of digital electronic technology teaching.
In order for students to learn VHDL, teachers should first teach themselves, but learning VHDL requires a language environment that can provide file input, logic synthesis, compilation and simulation. Now I recommend a language environment-Max+plusⅱII II software of ——ALTERA company, which can input digital circuit design files in graphic mode, text mode and waveform mode. Among them, the text mode supports VHDL, AHDL and VERILOG hardware description languages. The software has multiple component libraries (full-range TTL, macro function and macro function library), which can specify two ALTERA devices of MAX7000 and 10K 10 series, device pins and logic synthesis modes. The compiled download file can be programmed by programming hardware, and the software can be used for error location and design rule checking.
The software supports VHDL, 87 and 93 versions, and has all VHDL support libraries.
This software can help you learn to use CPLD products of ALTERA Company. ALTERA's CPLD products represent the development direction of PLD, which is comparable to XILINX's FPGA products, especially the company's AHDL language makes it easier to design digital systems.
The software is the 7.2 student version of the software series (the current industrial version is 8.0, and the price is 2000 yuan, which can only be used by one user). It has been decrypted and can be easily installed on any computer, especially suitable for teaching.
The software can complete the whole process of inputting design documents, specifying devices and pins, compiling, simulating and downloading (required by hardware). If there is no hardware, all steps can be carried out except downloading, which shows that it is a very good teaching software.
The software supports WINDOWS 95 platform, takes up about 60 megabytes of hard disk space, has simple menu and is easy to use, which is really a rare environment for learning VHDL language.
In order to make it convenient for teachers to use the software, a supporting textbook, Digital System Design, has been compiled for the software. The textbook *** 170 contains four parts: VHDL language, CPLD introduction, AHDL language and Max+plusⅱ Ⅱ software. There are many examples about the use of VHDL and AHDL in the textbook, especially the examples of learning software step by step and using VHDL and AHDL will be helpful.
Every example in the textbook has been written with MAX+PLUS Ⅱ Ⅱ software, which proves the correctness of the example, and most of the examples give simulation results.
Software and teaching materials can help you learn VHDL language and teach CPLD, so that teaching can reach a higher level and meet the needs of cultivating cross-century talents.
