NAME

GENLIB_BUS - Creates a bus name for netlist

SYNOPSIS

#include <genlib.h>
char ∗GENLIB_BUS(busname, from, to);
char ∗busname;
long from, to;

See the file man1/alc_origin.1.

PARAMETERS

busname: Common signal name for a bus
from: Starting index of the set of signal, from included
to: Ending index of the set of signal, to included

DESCRIPTION

GENLIB_BUS Creates a set of names, based upon a common name, valid for the genlib netlist functions that manipulate the signal, and/or connector, concept. They are:

LOINS(3)
LOCON(3)

The from, to arguments give the boundaries of the bus to be created, both of them being included in the set. The function allows increasing or decreasing order busses, as one could expect.
This function has a constant equivalent, it means that if the from, to values are known at compilation time, one should better use, for readability purposes, the "[n:m]" construct.

EXAMPLE

#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, GENLIB_BUS("sig", b, e);
	GENLIB_LOCON("o[2:0]", OUTPUT, "sigout[4:6]");
	/∗ Place an instance ∗/
	GENLIB_LOINS("model","instance", GENLIB_BUS("sig", e/2), "sigout[6]", EOL);
	/∗ Save all that on disk ∗/
	GENLIB_SAVE_LOFIG();
}
