作用范围仅限于单个module 3)Systemverilog: 参数可以在多个模块里共同使用,可以用typedef 代替单调乏味的宏。
SystemVerilog 在通过不同类型的数组构建复杂的数据结构方面提供了很大的灵活性。 静态阵列 动态阵列 关联数组 队列 Static Arrays 静态数组是指其大小在编译时间之前已知的数组。在下面显示的示例中,声明了一个8位宽的静态数组,为其分配了一些值并循环访问以打印其值。 moduletb;bit[7:0] m_data;// A vector o...

SystemVerilog adds several enhancements to Verilog for representing large amounts of data. The Verilog array constructs are extended both in how data can be represented and for operations on arrays. Structure and union data types have been added to Verilog as a means to represent collections of ...
Arrays are allowed in Verilog for reg, wire, integer and real data types. reg y1 [11:0]; // y is an scalar reg array of depth=12, each 1-bit wide wire [0:7] y2 [3:0] // y is an 8-bit vector net with a depth of 4 reg [7:0] y3 [0:1][0:3]; // y is a 2D...
Verilog arrays are plain, simple, but quite limited. They really do not have many features beyond the basics of grouping signals together into a multidimensional structure. SystemVerilog arrays, on the other hand, are much more flexible and have a wide range of new features and uses. In the...
Edit, save, simulate, synthesize SystemVerilog, Verilog, VHDL and other HDLs from your web browser.
Designing FPGAs Into a System While there are many advantages to FPGAs, such as speed, reliability, and flexibility, there are also trade-offs associated with FPGAs. FPGAs do not have the driver ecosystem and code/IP base that microprocessor architectures and OSs do. In addition, microproces...
The following code snippet does not synthesize with the native Quartus synthesis tool, which supposedly supports System Verilog (The SV compile switch is set in Quartus): typedef struct packed{ bit[9:0] A; bit B; bit C; bit D; bit E; bit F; bit[9...
The adoption of FPGA technology continues to increase as higher-level tools such as LabVIEW are making FPGAs more accessible. It is still important, however, to look inside the FPGA and appreciate how much is actually happening when block diagrams are compiled down to execute in silicon. Compari...
