NAME

GENLIB_PLACE_VIA_REF - put a via on top of a reference belonging to an instance in the current figure

SYNOPSYS

#include <genlib.h>
void GENLIB_PLACE_VIA_REF(insname, refname, viatype)
char  ∗insname, ∗refname;
char viatype;

See the file buster/alliance/alc_origin.1.en.gz.

PARAMETERS

insname: Name of the instance in the which the reference is to be searched for
refname: Name of the reference to be used as target point
viatype: Type of via to be placed

DESCRIPTION

PLACE_VIA_REF places a via of type viatype on top of the specified reference, refname, in the instance called insname. This function may be used to generate many cells from a single one, in order to "program" decoders for example, or in conjuction with PLACE_SEG_REF(3) or PLACE_CON_REF(3) to translate virtual connectors into fixed ones.
The viatype argument may take the following legal values:

CONT_POLY: links POLY and ALU1
CONT_DIF_N: links NDIF and ALU1
CONT_DIF_P: links PDIF and ALU1
CONT_BODY_N: links NTIE and ALU1
CONT_BODY_P: links PTIE and ALU1
CONT_VIA: links ALU1 and ALU2
CONT_VIA2: links ALU2 and ALU3

ERRORS

"GENLIB_PLACE_VIA_REF impossible : missing GENLIB_DEF_PHFIG"

No figure has been yet specified by a call to DEF_PHFIG. So it isn't possible to place a reference inside it. you must call DEF_PHFIG before any other layout action.

"illegal getphins : instance insname does not exist"

The instance called insname does not currently belong to the figure.

"illegal getphref : references called refname does not exist"

No reference called refname exists in the model of the instance insname.

EXAMPLE

#include <genlib.h>
main()
{
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_PHFIG("cell");
	GENLIB_PLACE("gaci0_b", "r1", NOSYM, 23L, 54L);
	/∗ Put a reference ∗/
	GENLIB_PLACE_VIA_REF("a_0", "r1", CONT_VIA);
	/∗ Save that on disk ∗/
	GENLIB_SAVE_PHFIG();
}
