65. What are the constraints? Is all constraints are bidirectional? 约束是什么?所有的约束都是双向的吗? 约束是用于限制随机变量生成的条件。它们可以确保生成的随机值满足某些特定的要求。并不是所有的约束都是双向的;有些约束是单向的,只对特定变量起作用。双向约束意味着两个变量之间的关系是相互依赖的,但大...
Yes, it's possible to override existing constraints in SystemVerilog using inline constraints or inheritance. 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 no...

You can write constraints in a variety of ways. Constraints should not contradict each other, else randomization will fail at run-time. classmyPacket;randbit[7:0]mode;randcbit[7:0]key;intlow,high;constraintc_simple{mode>2;key==3;}// This won't work, because it contradicts c_simple -...
