LORES(3) MBK LOGICAL STRUCTURE DEFINITIONS LORES(3)NAME
lores - mbk logical resistor
DESCRIPTION
The lores is used to describe a logical resistor. Please note, this description is different from the RCN description and has a different
purpose: the created resistor is a functional logical resistor, not a parasitic resistor. For the time being, only MIM (i.e. metal) resis-
tor type is supported.
The declarations needed to work on lores are available in the header file "/labo/include/mlo.h".
The following C structure supports the description of the logical resistor :
typedef struct lores
{
struct lores *NEXT ;
struct locon *RCON1 ;
struct locon *RCON2 ;
char *NAME ;
double RESI ;
char TYPE ;
struct ptype *USER ;
} lores_list ;
NEXT Pointer to the next lores of the list.
RCON1 Pointer to the rcon1 connector of the resistor. This connector is, of course unique. See locon(3) for details.
RCON2 Pointer to the rcon2 connector of the resistor. This connector is, of course unique. See locon(3) for details.
NAME Resistor instance name
RESI Resistance value
TYPE Layer type of the resistor. One legal values is available :
RESMIM Metal resistor.
USER Pointer to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share informations on the
resistor. This field is used with the LORES_INFO(3) ptype to store physical informations.

addlores - create a logical resistor
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.

SYNOPSYS
#include "mlo.h"
lores_list *addlores(ptfig,type,resi,rcon1,rcon2,name)
lofig_list *ptfig ;
char type ;
double resi ;
losig_list *rcon1, *rcon2 ;
const char *name ;
PARAMETERS
ptfig Pointer to the figure in which the resistor should be added
type Resistor type
resi Resistor value in Ohms
rcon1 Pointer to the signal to be connected on the resistor top plate
rcon2 Pointer to the signal to be connected on the resistor bottom plate
name Resistor instance name
DESCRIPTION
addlores creates a new resistor, and adds it to the list of resistors pointed to by ptfig -> LORES. The new resistor is added in front of
the list, and becomes itself the list head.
The type parameter can take one value :
RESMIM for a metal resistor
The resi argument is the resistor value in Ohms.
Two connectors are created each time a resistor is added, and the rcon1 and rcon2 losigs are attached to the SIG field of the locon of the
appropriate connector. The connectors names are rcon1 and rcon2; their direction, DIR, are set to 'R', and their TYPE INTERNAL. For
details on the structures, see locon(3) and lores(3).
RETURN VALUE
addlores returns a pointer to the newly created resistor.
ERRORS
"*** mbk error *** illegal resistor type : type"
The type is not a legal resistor type.
EXAMPLE
#include "mlo.h"
void parallel_resistors(void) /* netlist of two parallel resistors */
{
lofig_list *pt = NULL ;
losig_list *in = NULL ;
losig_list *out = NULL ;
pt = addlofig("parallel_resistors") ;
addlocon(pt,"in",in = givelosig(pt,0),IN) ;
addlocon(pt,"out",out = givelosig(pt,1),OUT) ;
addlores(pt,RESMIM,0.2e-6,in,out,"res1") ;
addlores(pt,RESMIM,0.2e-6,in,out,"res2") ;
