@ -312,6 +312,10 @@ Verilog Attributes and non-standard features
passes to identify input and output ports of cells. The Verilog backend
also does not output blackbox modules on default.
- The ``whitebox`` attribute on modules triggers the same behavior as
``blackbox``, but is for whitebox modules, i.e. library modules that
contain a behavioral model of the cell type.
- The ``dynports`` attribute is used by the Verilog front-end to mark modules
that have ports with a width that depends on a parameter.
