如果你的代码试图从一个越界的地址中读取数据,那么system verilog将返回数组元素类型的缺省值。也就是说,对于一个元素为四状态类型的数组,例如logic,返回的是X,而对于双状态类型例如int或bit,则返回0。这适用于所有数组类型。 很多system verilog仿真器在存放数组元素时使用32bit的字边界,所以byte,shortint和int都是...
支持对数据库的SQL访问 将已打开的C文件句柄与Verilog文件标识符相关联。通过这种机制,将提供广泛的有趣的新功能,包括对临时文件的支持,以及通过TCP / IP套接字和其他网络机制的通信。 如果可以在SystemVerilog和诸如Python之类的脚本语言之间建立紧密的连接,将会产生大量激动人心的可能性。这个想法已经通过PyHVL项目以...
systemverilog parameter默认位宽 在SystemVerilog中,可以为parameter提供默认位宽。如果没有指定位宽,则默认为32位。例如: ```systemverilog module MyModule #(parameter WIDTH = 32); //模块定义 endmodule ``` 上述代码定义了一个名为MyModule的模块,具有一个名为WIDTH的parameter。如果未在模块的实例化中为WIDTH...

Public parameters in the SystemVerilog code may cause shadowing in the generated C++ code if its name happens to coincide with an autogenerated name. Obfuscating the autogenerated variable names or adding some prefix would help mitigate this issue. The fix for one collision is at #3855. Here'...
parameter在#后面是“可以提供给外部调用”的常数参数。这是VERILOG2001的新标准，实习系统级的抽象。
Vivado 2018.3 claims support for hierarchical names in SystemVerilog. This is certainly true for signals, and is also true for parameters inside of an interface - that is, an interface called "bus" with a localparam called "BYTES" can
I can't quite read the examples you posted. In any case, we're using Parameterized SystemVerilog interfaces now in Vivado. We're still tweaking our use-cases - the latest release of Vivado (2015.3) is supposed to include some better support.
In this work, a sigma-delta analog-to-digital converter (ADC), a voltage-controlled oscillator (VCO) and a digital phase-locked loop (PLL) are implemented as real number models using SystemVerilog. This paper is an extended version of work previously published by the authors. Herein, more ...
