GENLIB_PHVIA(3)

NAME

GENLIB_PHVIA - place a physical via in the current figure at absolute coordinates

SYNOPSYS

#include <genlib.h>
void GENLIB_PHVIA(type, x, y)
char type;
long x, y;

PARAMETERS

type: Type of the contact to be made

x, y: Absolute coordinates of the via

DESCRIPTION

PHVIA adds a via in the current layout cell, at the specified coordinates. The type 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

C_X_N: corner for L-shaped (and S-shaped) N transistor

C_X_P: corner for L-shaped (and S-shaped) P transistor

ERRORS

"GENLIB_PHVIA 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 via inside it. you must call DEF_PHFIG before any other layout action.

"illegal addphvia : type is XX at x, y"

The type parameter does not have a legal value, but XX.

EXAMPLE

#include <genlib.h>
main()
{
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_PHFIG("cell");
	.
	/∗ Put a via ∗/
	GENLIB_PHVIA(CONT_VIA, 12L, 10L);
	.
	.
	GENLIB_DEF_AB(0L, 0L, 0L, 0L);
	/∗ Save that on disk ∗/
	GENLIB_SAVE_PHFIG();
}
