# GENLIB\_COPY\_UP\_REF(3)

copy a physical reference from an instance in the current figure

## NAME

GENLIB\_COPY\_UP\_REF - copy a physical reference from an instance in the current figure

## SYNOPSYS

```
#include <genlib.h>
void GENLIB_COPY_UP_REF(refname, insname, newname)
char ∗refname, ∗insname, ∗newname;
```

## PARAMETERS

- *refname*

  Name of the reference in the instance

- *insname*

  Name of the instance in the which the reference is to be searched for

- *newname*

  Name to be given to the reference in the current figure

## DESCRIPTION

**COPY\_UP\_REF** adds a reference in the current layout cell. All the reference's attributes are copied from the first found reference called *refname* in the instance *insname*. The designer should avoid to give to several refences the same name if he plans to use this function. The new reference is given the name *newname*. The main purpose of this function is to copy a reference in the upper hierarchical level, so it can be used as *virtual* connector, for the data-path router. See **dpr**(1) for details. layout.

## ERRORS

**"GENLIB\_COPY\_UP\_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.

**"GENLIB\_COPY\_UP\_REF impossible : reference** *refname* **does not exist"**

The reference *refname* does not exist in the model of the instance *insname*.

## EXAMPLE

```
#include <genlib.h>
main()
{
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_PHFIG("cell");
	GENLIB_PLACE("z2l_y", "r1", NOSYM, 23L, 54L);
	/∗ Put a reference ∗/
	GENLIB_COPY_UP_REF("mux0_s", "r1", "out_s");
	/∗ Save that on disk ∗/
	GENLIB_SAVE_PHFIG();
}
```
