Verilog 的数据类型主要是线网和变量,即 wire, reg, integer,都是四值逻辑(0、1、x、z) 在verilog基础上,SV增加了二值逻辑(0、1)变量来简化运算, 包含 bit, byte, shortint, int, longint 变量。 SV中logic与verilog中的reg变量对应,为四值逻辑的无符号数;bit为二值逻辑的无符号数; byte, int, short...
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...

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 ...
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

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 ...
“ chip IP integrator. This paper shares the approach, methodology and the results on a real-life system comprising several RTL design blocks in Verilog each having around a quarter of million instances as well as on an ARM 4 CPU test chip design. The tool maintains two dynamic views â...
