Issue: Error in RegblockExporter.export regarding buffer_writes

[xcfuisnewhere]

Hi everyone, can you please help me about this problem below:

1. When I use RegblockExporter.export() function to generate rtl code, I got an error like this:

   Traceback (most recent call last):
   File "C:\W_Work\2024_01_04_RegTool2.0\Tool\2.DATA\ipxact2rtl.py", line 42, in <module>
   rtl.export(

   self.ds = DesignState(top_node, kwargs)

   self.current_action = self.do_enter(node, listener)
   File "C:\Users\xcfu\AppData\Local\Programs\Python\Python310\lib\site-packages\systemrdl\walker.py", line 193, in do_enter
   new_action = listener.enter_Reg(node) or WalkerAction.Continue

   self.ds.has_buffered_write_regs = self.ds.has_buffered_write_regs or bool(node.get_property('buffer_writes'))
   File "C:\Users\xcfu\AppData\Local\Programs\Python\Python310\lib\site-packages\systemrdl\node.py", line 397, in get_property
   raise LookupError("Unknown property '%s'" % prop_name)
   LookupError: Unknown property 'buffer_writes'

2. My python code is as follows:

   
   rdlc = RDLCompiler()
   ipxact = IPXACTImporter(rdlc)

try: ipxact.import_file("xxxx.xml") root = rdlc.elaborate() regmap = root.find_by_path('cmsdk_apb_watchdog__APB_Watchdog_Slave_MM.addressBlock0') except RDLCompileError: sys.exit(1)

rtl= RegblockExporter() rtl.export( regmap, "./rtl/", cpuif_cls=AXI4Lite_Cpuif )

You are missing the step where UDPs required for the regblock generator get registered. See the example here: https://peakrdl-regblock.readthedocs.io/en/latest/api.html#example

Also, be sure to check out the PeakRDL command line tool - it ties together all of the PeakRDL tools into one easy to use toolchain.

Thank you so much for your help! I have another question to ask. When editing IP-XACT and SystemRDL files with a text editor, it doesn't feel very intuitive. I prefer to edit each entry in a more tabular format. Do you have any recommended editors or tools for this?

[amykyta3]

If you use VSCode, I have made a SystemRDL extension that adds syntax highlighting and templates. Its still a text editor, but at least it can be easier to read. Once you get used to the language, it becomes pretty intuitive. I have a tutorial here if you need some guidance: https://peakrdl.readthedocs.io/en/latest/systemrdl-tutorial.html

I dont have a good recommendation for a tabular method. Partly because I prefer just editing RDL directly.

Agree that editing IP-XACT files is an absolute pain. I avoid it whenever possible. I know of the Kactus2 tool which is a graphical editor for IP-XACT, but I have not used it too much. Usually I'll generate IP-XACT from a SystemRDL file if I absolutely need to. (via peakrdl ipxact)

Thank you very much！ Your suggestions have been immensely helpful to me.
