addHierarchy()

static void addHierarchy ( hw::HierPathOp  path, FModuleOp  dut, InstanceOp  wrapperInst, StringAttr  oldDutNameAttr  )

static

Add an extra level of hierarchy to a hierarchical path that places the wrapper instance after the DUT.

This appends to the existing path immediately after the dut.

E.g., this is converting:

firrtl.hierpath [@Top::@dut, @DUT]

Into:

firrtl.hierpath [@Top::@dut, @DUT::@wrapper, @Wrapper]

The oldDutNameAttr parameter controls the insertion point. I.e., this is the location of a module wehre an insertion will happen. By separating this from the dut paramter, this allows this function to work for both the moveDut=false and moveDut=true cases. In the moveDut=false case the dut and oldDutNameAttr refer to the same module.
