SYNOPSYS¶

#include "mlo.h"
loins_list ∗addloins(ptfig, insname, ptmodel, sigchain)
lofig_list ∗ptfig;
char ∗insname;
lofig_list ∗ptmodel;
chain_list ∗sigchain;

PARAMETERS¶

ptfig

Pointer to the figure in which the instance should be added

insname

Instance name

ptmodel

Pointer to the instance model

sigchain

Pointer to chain list of signal pointers

DESCRIPTION¶

addloins creates a new instance, and adds it to the list of instances pointed to by ptfig->LOINS. The new instance is added in front of the list, and becomes itself the list head.
The parameter insname fills the INSNAME field of the loins structure.
The ptmodel is used for two purposes. First, the ptmodel->NAME fills the FIGNAME field. Second, the connectors of the figure pointed to by ptmodel are duplicated in the LOCON field, but the signals linked to each connector are the one given in the sigchain argument. See chain(3) for details on chain_lists.
The matching is done in order, it means that the first connector is linked to the first signal of the sigchain, and so on. Care must be taken when instanciating in order to warranty the validity of the netlist. For details on the structure, see loins(3).

RETURN VALUE¶

addloins returns a pointer to the newly created instance.

ERRORS¶

"∗∗∗ mbk error ∗∗∗ addloins impossible : instance insname already exist in figure ptfig->NAME"

EXAMPLE¶

#include "mlo.h"
void add_na2_y(pt, in1, in2, out) /∗ add an instance of na2_y ∗/
lofig_list ∗pt; /∗ pointer to the figure ∗/
long in1, in2, out; /∗ signals indexes ∗/
{
chain_list ∗signal = NULL;
	/∗ get the pointer when signal index is known ∗/
	signal = addchain(signal, (void ∗)givelosig(pt, in1));
	signal = addchain(signal, (void ∗)givelosig(pt, in2));
	signal = addchain(signal, (void ∗)givelosig(pt, out));
	/∗ get vdd and vss ∗/
	signal = addchain(signal, (void ∗)give_vdd(pt));
	signal = addchain(signal, (void ∗)give_vss(pt));
	/∗ reverse the list ∗/
	signal = reverse(signal);
	addloins(pt, "nand", getlofig("na2_y"), signal);
}
