Perform the export!
Parameters
----------
node: systemrdl.Node
Top-level node to export. Can be the top-level `RootNode` or any
internal `AddrmapNode`.
path: str
Output file.
export_as_package: bool
If True (Default), UVM register model is exported as a SystemVerilog
package. Package name is based on the output file name.
If False, register model is exported as an includable header.
reuse_class_definitions: bool
If True (Default), exporter attempts to re-use class definitions
where possible. Class names are based on the lexical scope of the
original SystemRDL definitions.
If False, class definitions are not reused. Class names are based on
the instance's hierarchical path.
use_uvm_factory: bool
If True, class definitions and class instances are created using the
UVM factory.
If False (Default), UVM factory is disabled. Classes are created
directly via new() constructors.
