NAME

       GENLIB_BUS - Creates a bus name for netlist

SYNOPSYS

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

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  beeing
       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();
       }
