char ∗busname;

Common signal name for a bus
Index of the demanded signal belonging to the bus

ELM Creates a single element bus names valid for the genlib netlist functions that manipulate the signal, and/or connector, concept. They are:

LOINS(3)
LOCON(3)
The index argument gives the index of the name to be created.
This function has a constant equivalent, it means that if the index value is known at compilation time, one should better use, for readability purposes, the "[n]" construct. 

#include <genlib.h>
main()
{
int b = 0;
int e = 12;
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_LOFIG("mycell");
	/∗ define interface  ∗/
	GENLIB_LOCON(GENLIB_BUS("i", b, e), INPUT, BUS("sig", b, e);
	GENLIB_LOCON("o[2:0]", OUTPUT, "sigout[4:6]");
	/∗ Place an instance ∗/
	GENLIB_LOINS("model","instance", GENLIB_ELM("sig", e/2), "sigout[6]", EOL);
	/∗ Save all that on disk ∗/
	GENLIB_SAVE_LOFIG();
}

genlib(1), GENLIB_BUS(3).
