    hInst is hierarchical instance. Usually equivalent to a hierarchical module in Verilog. Type "dbSchema hInst" for more information.

    If you have a hierarchy such as the following then U0 and instA/U1 are insts and instA is an hInst. hInsts are hierarchical modules which have insts inside them.

    module top(...);

    ...

         modA instA(...);

         INVXL U0(...) ;

    endmodule

    module modA(...);

    ...

       BUFXL U1(...);

    endmodule
