GENLIB_SC_PLACE.3(October 1, 1997) GENLIB_SC_PLACE.3(October 1, 1997)

NAME

GENLIB_SC_PLACE - place an instance in the current figure at absolute coordinates

SYNOPSYS

#include <genlib.h>
void GENLIB_SC_PLACE(insname, symetry, x, y)
char ∗insname;
char symetry;
long x,y;

ORIGIN

PARAMETERS

insname
Name to be given to the instance on the model
symetry
Geometrical operation to be performed on the instance before beeing placed
x, y
Coordinates of the lower left corner of the abutment box of the model in the current figure

DESCRIPTION

SC_PLACE add an instance in the current cell. The bottom left corner of the instance is placed, after beeing symetrized and/or rotated, at (x, y) coordinates. 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 placed instance becomes the new "reference instance", used in the relative placement functions.
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_PLACE 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_PLACE impossible : missing GENLIB_DEF_LOFIG"
The current netlist figure is not define, so SC_PLACE 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_PLACE 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);
	GENLIB_SC_PLACE("ins2", NOSYM, 80L, 100L);
	/∗ Save all that on disk ∗/
	GENLIB_SAVE_PHSC();
}
