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 con-
nector, concept. They are:
LOINS(3)
LOCON(3)
The from, to arguments give the boundaries of the bus to be created, both of them beeing included in the set. The function allows increas-
ing 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();
}
