    We now have a download button in the "Project" view, which allows downloading all the register maps in a project at once.

    Hi Luca, thanks for your suggestion. In airhdl all registers are reset to their default values upon assertion of the axi_aresetn signal. Is that what you call the "software reset"?

    Thanks for your comment. May I ask what kind of bus or interconnect system you use in your embedded systems?

    Thanks for your suggestions. airhdl already supports write-one-to-clear (W1C) bits in registers of type "interrupt". Actually, all bits interrupt-type registers are W1C.

    That's correct. The interface only supports the AXI4-Lite protocol for now, which is limited to burst lengths of 1.

    Thanks for your suggestion! Do you have an example showing how such a driver could look like? Would it help to provide helper macros to set/extract the value of a given field from a given register, e.g. get_field_<reg>_<field>(), set_field_<reg>_<field>()?

    Guy.

    What I call an "interrupt" register is a register whose fields are set in the user logic, and reset by writing one from the bus. Do you actually use other modified write values than "oneToClear"?

    Actually, if you set a register's acces type to "interrupt", you should see the following elements in each <spirit:field> for that register:

    <spirit:volatile>true</spirit:volatile>
    <spirit:modifiedWriteValue>oneToClear</spirit:modifiedWriteValue>
