BlackBoxInst()

BlackBoxInst::BlackBoxInst ( std::string  type_name, std::string  inst_name, std::map< std::string, std::string >  params, std::map< std::string, std::string >  attrs, std::map< std::string, std::vector< std::string >>  input_port_conns, std::map< std::string, std::vector< std::string >>  output_port_conns, std::vector< Arc >  timing_arcs, std::map< std::string, double >  ports_tsu, std::map< std::string, double >  ports_tcq  )

Parameters

type_name	Instance type
inst_name	Instance name
params	Verilog parameters: Dictonary of <param_name,value>
attrs	Instance attributes: Dictonary of <attr_name,value>
input_port_conns	Port connections: Dictionary of <port,nets>
output_port_conns	Port connections: Dictionary of <port,nets>
timing_arcs	Combinational timing arcs
ports_tsu	Port setup checks
ports_tcq	Port clock-to-q delays

Member Function Documentation

find_port_size()

size_t BlackBoxInst::find_port_size ( std::string  port_name )

inline

print_blif()

void BlackBoxInst::print_blif ( std::ostream &  os, size_t &  unconn_count, int  depth = 0  )

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.

Implements Instance.

print_sdf()

void BlackBoxInst::print_sdf ( std::ostream &  os, int  depth = 0  )

inlineoverridevirtual

Print the current instanse in SDF, see print_blif() for argument descriptions.

Implements Instance.

print_verilog()

void BlackBoxInst::print_verilog ( std::ostream &  os, int  depth = 0  )

inlineoverridevirtual

Print the current instanse in Verilog, see print_blif() for argument descriptions.

Implements Instance.
