GENLIB_SC_TOP.3alc man page

GENLIB_SC_TOP — place an instance in the current figure at the right of the "reference instance"

Synopsis

#include <genlib.h>
void GENLIB_SC_TOP(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 being placed

Description

SC_TOP add an instance in the current cell. The bottom left corner of the abutment box of the instance is placed, after being 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 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_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_SC_TOP impossible : missing GENLIB_DEF_LOFIG"

The current netlist figure is not define, so SC_TOP 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_TOP 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_TOP("ins2", SYM_X);
	/∗ Save all that on disk ∗/
	GENLIB_SAVE_PHSC();
}
