UVM project topology

Posted on Edited on In

Most user-defined UVM classes are placed in separate files

Classes can only be compiled from a module or package scope

Recommendation:

  • Include related class files into a package
  • Import the package into modules where required

The UVM library is supplied in the package uvm_pkg

  • Import package to access library
  • The macro file uvm_macros.svh must be included separately
