bionic (3) GENLIB_BUS.3.gz

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();
       }
