Class definition outside module and package

Rama Kishore

Hi,

I'm new to SV verfication and hence appreciate your help on this.

Usually I've seen SV class definitions inside a module / package . I remember having read before that class definitions cannot exist outside these, and as such cannot be compiled standalone.

But strangely, I've seen IUS14.1 successfully compiling a  .sv file which contains only class definition. Do not see module/package constructs inside the file.

Am I missing something in my understanding? Thanks for your suggestions and help in advance.

Regards

Kishore

  • Thanks Stephen, for the very good explanation. That really helped my understanding.

     

    So, can I assume CU scope as analogous to Global scope in C/C++ ? Also, can you please elaborate a bit on "type is visible in all files that are compiled at the same time". What do you mean by the phrase "same time" in this context  - same .sv file that includes other .sv/.svh files  or  one compilation-tool invocation?
