Detailed Description

This class keeps track of global names at the module/interface level.

It is built in a global pass over the entire design and then frozen to allow concurrent accesses.

getParameterVerilogName()

StringRef circt::ExportVerilog::GlobalNameTable::getParameterVerilogName ( Operation *  module, StringAttr  paramName  ) const

inline

Return the string to use for the specified parameter name in the specified module.

Parameters may be renamed for a variety of reasons (e.g. conflicting with ports or Verilog keywords), and this returns the legalized name to use.
