.SH PARAMETERS
.TP 20

for the effective area computation
.TP
\fIptgrid\fP
Pointer to the signal to be connected on the transistor grid
.TP
\fIptsource\fP
Pointer to the signal to be connected on the transistor source
.TP

.SH DESCRIPTION
\fBaddlotrs\fP creates a new transistor, and adds it to the
list of transistors pointed to by \fIptfig\->LOTRS\fP. The new transistor is 
added in front of the list, and becomes itself the list head.
.br
The \fItype\fP parameter can take six values :
.RS
.TP 20
\fBTRANSN\fP
for a N channel transistor
.TP
\fBTRANSP\fP
for a P channel transistor
.TP
\fBTRANSN_FAST\fP
for a high speed N channel transistor
.TP
\fBTRANSP_FAST\fP
for a high speed P channel transistor
.TP
\fBTRANSN_HVIO\fP
for a low leakage N channel transistor
.TP
\fBTRANSP_HVIO\fP
for a low leakage P channel transistor
.RE
.LP
The \fIx\fP, \fIy\fP, \fIwidth\fP , \fIlength\fP, \fIps\fP, \fIpd\fP,
\fIxs\fP and \fIxd\fP,  arguments fill
respectivly the \fIX\fP, \fIY\fP, \fIWIDTH\fP, \fILENGTH\fP, \fIPS\fP,
\fIPD\fP, \fIXS\fP and \fIXD\fP fields.
.br
Four connectors are created each time a transistor is added, and the
\fIptgrid\fP, \fIptsource\fP, \fIptdrain\fP and \fIptbulk\fP \fBlosig\fPs are attached to
the \fISIG\fP field of the \fBlocon\fP of the appropriate connector. The
connectors names are \fIgrid\fP, \fIsource\fP, \fIdrain\fP and \fIbulk\fP, their
direction, \fIDIR\fP, are set to \fB'T'\fP, and their \fITYPE\fP \fBINTERNAL\fP.
For details on the structures, see \fBlocon\fP(3) and \fBlotrs\fR(3).
.SH RETURN VALUE
\fBaddlotrs\fP returns a pointer to the newly created transistor.
