ADDLOTRS(3)		      MBK LOGICAL FUNCTIONS		     ADDLOTRS(3)

NAME
     addlotrs - create a logical transistor

SYNOPSIS
     #include "mlo.h"
     lotrs_list *addlotrs(ptfig, type, x, y, width, length,
			    ps, pd, xs, xd,
			    ptgrid, ptsource, ptdrain, ptbulk, name)
     lofig_list *ptfig;
     char type;
     long x, y;
     unsigned short width, length;
     unsigned short ps, pd;
     unsigned short xs, xd;
     losig_list *ptgrid, *ptsource, *ptdrain, *ptbulk;
     const char *name;

PARAMETERS
     ptfig		 Pointer to the figure in which the transistor should be
			 added

     type		 transistor type

     x, y		 Transistor coordinates

     width, length	 Transistor grid width and length

     ps, pd		 Perimeters of the source and drain

     xs, xd		 Values  to  compute  the areas of the source and drain,
			 see lotrs(3) for the effective area computation

     ptgrid		 Pointer to the signal to be connected on the transistor
			 grid

     ptsource		 Pointer to the signal to be connected on the transistor
			 source

     ptdrain		 Pointer to the signal to be connected on the transistor
			 drain

     ptbulk		 Pointer to the signal to be connected on the transistor
			 bulk

     name		 Transistor instance name

DESCRIPTION
     addlotrs creates a new transistor, and adds it to the list  of  transistors
     pointed  to  by  ptfig->LOTRS.  The new transistor is added in front of the
     list, and becomes itself the list head.
     The type parameter can take six values :

	    TRANSN		for a N channel transistor

	    TRANSP		for a P channel transistor

	    TRANSN_FAST 	for a high speed N channel transistor

	    TRANSP_FAST 	for a high speed P channel transistor

	    TRANSN_HVIO 	for a low leakage N channel transistor

	    TRANSP_HVIO 	for a low leakage P channel transistor

     The x, y, width , length, ps, pd, xs and xd,   arguments  fill  respectivly
     the X, Y, WIDTH, LENGTH, PS, PD, XS and XD fields.
     Four  connectors  are  created each time a transistor is added, and the pt-
     grid, ptsource, ptdrain and ptbulk losigs are attached to the SIG field  of
     the  locon  of  the  appropriate  connector. The connectors names are grid,
     source, drain and bulk, their direction, DIR, are set  to	'T',  and  their
     TYPE INTERNAL.  For details on the structures, see locon(3) and lotrs(3).

RETURN VALUE
     addlotrs returns a pointer to the newly created transistor.

ERRORS
     "*** mbk error *** illegal transistor type : type"
	    The type is not a legal transistor type.

EXAMPLE
     #include "mlo.h"
     void n1_y() /* transistor netlist of an inverter */
     {
     lofig_list *pt;
     losig_list *in, *out, *vdd, *vss;
	pt = addlofig("n1_y");
	addlocon(pt, "in", in = givelosig(pt, 0), IN);
	addlocon(pt, "out", out = givelosig(pt, 1), OUT);
	addlocon(pt, "vdd", vdd = givelosig(pt, 2), IN);
	addlocon(pt, "vss", vdd = givelosig(pt, 3), IN);
	addlotrs(pt, TRANSN, 0, 0, 6, 1, in, vss, out, vss, trn_n1_y);
	addlotrs(pt, TRANSP, 0, 0, 12, 1, in, vdd, out, vdd, trp_n1_y);
     }
