HECTARE - Hamburg Elegant CreaTor from Accellera™ systemrdl™ to REgisters

This is a tool which generates AXI4-Lite slave from a description in SystemRDL.

It uses systemrdl-compiler as a front end and a custom backend to generate a VHDL module.

The HECTARE tool is developed by MicroTCA Tech Lab at DESY.

Tests

Several tests are provided in test folder

00_unit_test

This is a simple unit test based on the Python [] framework.

01_uvvm_simple

UVVM version: v2019.12.04

Regenerating the output products (in shell, from folder hdl):

$ ./gen_output.sh
Parsing finished.
generate_package
Generating mymodule.vhd ...
Generating mymodule_pkg.vhd ...
Done.

Running the test (in ModelSim, from folder work)

do ../scripts/compile_uvvm.do
do ../scripts/sim.do

02_hdlparse

Requires hdlparse from a fork (the one from pip is missing some features) available from https://github.com/andresmanelli/hdlparse on branch entity.

03_ordt_equivalence

Compares the output of HECTARE against Juniper® ordt.

Alias to ordt should be created, as explained here.
