Constructor & Destructor Documentation

LutInst()

LutInst::LutInst ( size_t  lut_size, LogicVec  lut_mask, std::string  inst_name, std::map< std::string, std::vector< std::string >>  port_conns, std::vector< Arc >  timing_arc_values  )

inline

< Public methods

Parameters

lut_size	The LUT size
lut_mask	The LUT mask representing the logic function
inst_name	The name of this instance
port_conns	The port connections of this instance. Key: port name, Value: connected nets
timing_arc_values	The timing arcs of this instance

Member Function Documentation

instance_name()

std::string LutInst::instance_name ( )

inline

print_blif()

void LutInst::print_blif ( std::ostream &  os, size_t &  unconn_count, int  depth  )

inlineoverridevirtual

Print the current instance in blif format.

Parameters

os	The output stream to print to
unconn_count	The current count of unconnected nets. BLIF has limitations requiring unconnected nets to be used to represent unconnected ports. To allow unique naming of these nets unconn_count is used to uniquify these names. Whenever creating an unconnected net (and using unconn_count to uniquify its name in the file) unconn_count should be incremented.
depth	Current indentation depth. This is used to figure-out how much indentation should be applied. This is purely for cosmetic formatting. Use indent() for generating consistent indentation.
