NAME

       GENLIB_LOSIG - declare an internal logical signal, or a vector of internal logical signals

SYNOPSYS

       #include <genlib.h>
       void GENLIB_LOSIG(name)
       char ∗name;

PARAMETERS

       name                Name of a signal to be declared

DESCRIPTION

       LOSIG creates the internal signal, or the set of internal signals coresponding to a vector
       description, represented by name.  See BUS(3) and ELM(3) for more details on vectors.
       The need for declaring signal is mostly felt when one wants to create a consistent  vector
       declaration,  for  file  formats  that do not allow partial or multiple declarations, like
       vhdl.  This way, a user can create a vector and access its member the way  he  wants,  but
       still having an internal consistent form.

       Warning             If  a  signal is declared with LOSIG, but not used, the resulting file
                           will have an internal node floating.  This is  not  an  error  from  a
                           genlib point of view, so the user must be aware of it.

EXAMPLE

       #include <genlib.h>
       main()
       {
            /∗ Create a figure to work on  ∗/
            GENLIB_DEF_LOFIG("cell");
            /∗ Define interface 
            GENLIB_LOCON(...
            /∗ declare buses ∗/
            GENLIB_LOSIG("grum[23:0]");
            GENLIB_LOSIG("iconection[0:7]");
            /∗ Place an instance ∗/
            GENLIB_LOINS("no2_y" ,"no3" ,"grum[12]" ,"a9_s" ,"new_no3_s" ,"vdd" ,"vss" ,0);
            GENLIB_LOINS("no2_y" ,"no4" ,"a12_s" ,"grum[6]" ,"no4_s" ,"vdd" ,"vss" ,0);
            GENLIB_LOINS("a2_y" ,"a22" ,"no3_s" ,"grum[15]" ,"a22_s" ,"vdd" ,"vss" ,0);
            /∗ Save all that on disk ∗/
            GENLIB_SAVE_LOFIG();
       }
