System Verilog (3) 枚举 (2) Enumeration 枚举类型,类似状态机 写了三个例子,包含枚举的声明、变量类型以及一些操作。 自定义一个枚举类型(traffic_lights),然后例化一个状态变量,monitor函数监控变量变化的时间($time)、变量名(.name),变量值 moduleenumeration_basic;//enum {red, green, yellow} traffic_light...

Verilogevent regions Arace conditionis a flaw in a system or process that is characterized by an output that exhibits an unexpected dependenceon the relative timing or ordering of events. It has two types: Hardware races and simulation induced races (unavoidable for event-driven simulation algorithm...
SystemVerilog allows you to create modules and classes that are parameterized. This makes them more flexible, and able to work on a range of data types
2.0 Verilog & SystemVerilog case statement modifiers Before going into detail about all of the case statement modifiers, we should look at the big picture as it relates to full_case, parallel_case, priority and unique. First ask yourself the questions: Why are the full_case parallel_case ...
The Verilog language, for example, was designed as an input language for a discrete-event simulator. The VHDL language also has an underlying discrete-event model of computation. Discrete-event modeling can be expensive–sorting time stamps can be time-consuming. Moreover, ironically, although ...

The chip integrator tool has been implemented in C++ and was tested on different Verilog RTL designs with extensive V2K syntax. The design blocks ranged from 250,000 to 500,000 instances and had up to half of million lines of Verilog. The tool dumps only the modified design files and copie...
