Hierarchical Reference 可以看到,a模块的XMR方式是从顶层的tb开始,根据Instance name找到的例化的a模块;这种根据结构和Instance Name跨模块调用的方式叫做Hierarchical Reference, 这也是最常见的方式。 优缺点如下: 在Verilog的一个module中,Instance Name是唯一的,所以该种方式指向性很明确,支持精细化地控制同一个module...

(2) items that are defined inside of a package are not permitted to make hierarchical references to items outside of that package. (this is also why we need virtual interface) Another thing is that wildcard import statement import pkg::*; doesn't import any identifiers (just make them can...
Verilog has the concept of hierarchical names that could be helpful for your intentions. But it's unsupported by Quartus in the general form (across modules). So there's no other option than wiring the arithmetic ports through all hierarchies, e.g. using a kind of bus. Generally...

“Verilog hierarchical reference” to see how to access module internal signals from the top/testbench module. Please only use hierarchical reference in verification, never use it in design. To get started, you could look at this:https://github.com/SymbioticEDA/riscv-formal/blob/master/docs/...
