NAME

       GENLIB_PLACE_TOP  -  place  a  physical  instance  in the current figure on the top of the
       "reference instance"

SYNOPSYS

       #include <genlib.h>
       void GENLIB_PLACE_TOP(modelname, insname, symetry)
       char ∗modelname, ∗insname;
       char symetry;

PARAMETERS

       modelname           Name of the layout figure to be instanciated

       insname             Name to be given to the instance on the model

       symetry             Geometrical operation to be performed on the  instance  before  beeing
                           placed

DESCRIPTION

       PLACE_TOP  add an instance of model modelname in the current layout cell.  The bottom left
       corner of the abutment box of the instance  is  placed,  after  beeing  symetrized  and/or
       rotated,  toward  the top left corner of the abutment box of the "reference instance". The
       newly placed instance becomes the "reference instance".
       The insname is the name given to the instance and must be  unique  at  a  given  hierarchy
       level.
       The symetry argument can take eight legal values :

       NOSYM               no geometrical operation is performed

       SYM_Y               Y becomes -Y, that means toward X axe symetry

       SYM_X               X becomes -X, that means toward Y axe symetry

       SYMXY               X becomes -X, Y becomes -Y

       ROT_P               a positive 90 degrees rotation take place

       ROT_M               a negative 90 degrees rotation take place

       SY_RP               Y becomes -Y, and then a positive 90 degrees rotation take place

       SY_RM               becomes -Y, and then a negative 90 degrees rotation take place

       The model of the figure to be placed must be available, on disk or in memory.  The path to
       the library is  specified  in  the  MBK_CATA_LIB  (1)  and  MBK_WORK_LIB  (1)  environment
       variables, and its format is given by the MBK_IN_PH (1) environment variable.

ERRORS

       "GENLIB_PLACE_TOP impossible : missing GENLIB_DEF_PHFIG"
              No  figure  has  been yet specified by a call to DEF_PHFIG. So it isn't possible to
              place an instance inside it.  you must  call  DEF_PHFIG  before  any  other  layout
              action.
       "GENLIB_PLACE_TOP impossible : No previous instance"
              There  are  no  instances  placed in the current layout cell, so it's impossible to
              know where to place from. Use a PLACE call before.
       "illegal addphins : transformation is x in insname"
              The symetry parameter is not one of the define given, but has the integer value x.

EXAMPLE

       #include <genlib.h>
       main()
       {
            /∗ Create a figure to work on  ∗/
            GENLIB_DEF_PHFIG("cell");
            /∗ Place two instances ∗/
            GENLIB_PLACE("dgl", "ins1", ROT_P, 0L, 0L);
            GENLIB_PLACE_TOP("idv", "ins2", SY_RP);
            /∗ Save all that on disk ∗/
            GENLIB_SAVE_PHFIG();
       }
