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();
       }
