通过使用rand和constraint关键字,可以在测试平台中定义随机变量及其约束条件,从而生成多样化的测试用例,提高验证覆盖率。 7. in SystemVerilog which array type is preferred for memory declaration and why? 在SystemVerilog中,哪种数组类型最适合内存声明,为什么? 对于内存声明,通常推荐使用静态数组(static arrays)。
classABC;randbit[3:0]data;constraintc_data{datainside{[5:10]};}endclassmoduletb;initialbeginABC abc=new;// Use inline constraint to override with new value// Note that this should not contradict the hard constraints in ABCabc.randomize()with{data==8;};endendmodule ...

In verilog there are no constructs to constraint randomization. Fallowing example demonstrated how to generate random number between 0 to 10.Using % operation, the remainder of any number is always between 0 to 10.EXAMPLE: module Tb(); integer add_1;...
