Resistors 1.00 (Default branch)
12-17-2008
Resistors is a program to calculate the most suitable E-series resistors for voltage dividers or for generating other values by putting two resistors in parallel. It is especially useful for selecting resistor values for the voltage dividers used in variable voltage regulators. In effect, the voltage in the middle of the divider is known, and you want to achieve a regulated voltage (the top value). |

ADDLORES(3) MBK LOGICAL FUNCTIONS ADDLORES(3) NAME
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. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr 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") ; } SEE ALSO
