VHDL模型结构分析

Analysis of the VHDL model structure and its applications

介绍了新型硬件描述语言ＶＨＤＬ的发展及特点；分析了该语言中的３大结构模型，即性能状态、定时、结构化模型；讨论了贯穿语言始终的２个核心——进程和信号；

The development and its features of a new type hardware description language, VHDL, is introduced. Its three structure models, behavioural timing and modeling, are analyzed and two key problems, process and signal, are discussed also. Finally, several circuit description examples are given.
