uHAL Register Map Tool

This is a python package designed to convert a uHAL-compatible XML address table into a set of hierarchical VHDL records who structure mirrors the XML address table itself.

It runs on python2 or python3 and can create either AXI or Wishbone decoders.

Required packages

lxml argparse

Basic Usage

build_vhdl_packages.py
    [--simple SIMPLE]
    [--verbose VERBOSE]
    [--debug DEBUG]
    [--mapTemplate MAPTEMPLATE]
    [--pkgTemplate PKGTEMPLATE]
    [--outpath OUTPATH]
    [--xmlpath XMLPATH] name

Examples

MEM_TEST.xml

Generate MEM_TEST_map.vhd and MEM_TEST_pkg.vhd in ./test/simple using the xmlfile ./example_xml/MEM_TEST.xml using the map template file templates/axi_generic/template_map_withbram.vhd

• with the simple parser (i.e. no uHAL)

./build_vhdl_packages.py -s True -x example_xml/MEM_TEST.xml -o test/simple \
    --mapTemplate templates/axi_generic/template_map_withbram.vhd MEM_TEST

• with the normal uHAL parser (working python uHAL must be installed)

./build_vhdl_packages.py -x example_xml/MEM_TEST.xml -o test/uHAL/ \
    --mapTemplate templates/axi_generic/template_map_withbram.vhd MEM_TEST

CM_USP.xml

Generate CM_USP_map.vhd and CM_USP_pkg.vhd in ./test/simple using the xmlfile ./example_xml/CM_USP.xml using the map template file templates/axi_generic/template_map_withbram.vhd

• with the simple parser (i.e. no uHAL)

./build_vhdl_packages.py -s True -x example_xml/CM_USP.xml -o test/simple  CM_USP

• with the normal uHAL parser (working python uHAL must be installed)

./build_vhdl_packages.py -x example_xml/CM_USP.xml -o test/uHAL CM_USP
