the separate items in the event expression must be separated by the keyword “or”. I have used the Verilog-1995 syntax in all the code examples so far. But here is the same flip-flop code example written with the Verilog
Verilog函数类似于软件函数(C或Pascal),是从表达式中调用的。函数接受一个或多个参数(输入)并返回一个结果。一个可以为字节范围的数据生成奇偶校验的可重用函数的例子如下所示。 示例2-5函数调用 DATA_OUT[6:0] = DATA_IN[6:0]; DATA_OUT[7] = par_gen_func(DATA_IN[6:0]); 2.4.2.2 任务 为每个任...
Real Intent derives its RTL linting rules from industry standards, including Reuse Methodology Manual and STARC, and well-researched papers, and provides a built-in policy to enable all of the lowRISC Verilog Coding Style rules. Real Intent uses its deep expertise to filter out only the relevant...
