NAME

       GENLIB_SC_LEFT - place an instance in the current figure at the right of the "reference instance"

SYNOPSYS

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

PARAMETERS

       insname             Name to be given to the instance on the model

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

DESCRIPTION

       SC_LEFT  add an instance in the current cell. The bottom right corner of the abutment box of the instance
       is placed, after beeing symetrized and/or rotated, toward the bottom left corner of the abutment  box  of
       the  "reference  instance".  The  newly  placed instance becomes the "reference instance".  The placement
       takes place only if the netlist is up to day, because the model of the instance is seeked there, in order
       to ensure consistency.

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

ERRORS

       "GENLIB_SC_LEFT 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_SC_LEFT impossible : missing GENLIB_DEF_LOFIG"
              The current netlist figure is not define, so SC_LEFT doesn't know where to pick up  the  model.  A
              DEF_LOFIG or a DEF_PHSC is to be performed to avoid this error.
       "GENLIB_SC_LEFT impossible : no logical instance insname"
              The  instance  insname does not exist in the netlist representation of the cell. It may lead us to
              believe that there is a consistency problem between the two representation of this cell.
       "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_PHSC("cell");
            /∗ Place two instances ∗/
            GENLIB_SC_PLACE("ins1", NOSYM, 0L, 0L);
            /∗ negative placement values are allowed ∗/
            GENLIB_SC_LEFT("ins2", SYM_Y);
            /∗ Save all that on disk ∗/
            GENLIB_SAVE_PHSC();
       }
