Detailed Description

the class for modification to verilog

Constructor & Destructor Documentation

ilang::VerilogModifier::VerilogModifier	(	VerilogInfo *	_vlg_info_ptr,
		port_decl_style_t	port_decl_style,
		bool	add_keep_or_not,
		const std::map< std::string, int > &	_sup_width_info
	)

Constructor:

Parameters

[in]	pointer	to a verilog info class
[in]	the	style: 0 auto deteremined, 1 Old, 2 New

void ilang::VerilogModifier::ReadModifyWrite	(	const std::string &	filename,
		std::istream &	fin,
		std::ostream &	fout
	)

do the work : read from fin and append to fout, fout needs to be open with append option
