A Vim plugin that facilitates Verilog netlist tracing. It is called Birdie because this name sounds like the commercial tool V**d*, and the user can hop like a bird going from one place to another in the Verilog netlist forrest.
pip install hdlConvertor
If you cannot acces the network, you can install using the included Python Wheel file converted from the official Egg file:
pip install python/hdlConverter/hdlConvertor-2.3-py38-cp38-linux_x86_64.whl
# If the above command does not work, try using the the following build
pip install python/hdlConverter/hdlConvertor-2.3-cp311-cp311-linux_x86_64.whl
Just :source the given vim_plugin/birdie.vim
Commands should be invoked in the window showing the netlist.
Parse a Verilog netlist using the closed source parser:
:Parse
:ParseAll
The parser is a binary compatible with x86_64 Linux distros with kernel > = 2.6.32. :Parse just extracts the user-defined Verilog modules and instances; whereas :ParseAll extracts everything.
Show the information of the module under the cursor:
:Module
Go to the definition of the module whose name matches with the given regular expression:
:GoToModule <module name regex, e.g. free.*dom>
Go to the declaration of the instance whose instance path matches with the given regular expression:
:GoToInstance <instance path regex, e.g. /top_module_name/path/to/instanc.*>
Extract the definition of a module and put it on a separate buffer/window:
:OneModule <module name regex, e.g. free.*dom>
Show the hierarchy of the design:
:Hier
