DESCRIPTION

53       addlotrs creates a new transistor, and adds it to the list of  transis‐
54       tors  pointed  to by ptfig->LOTRS. The new transistor is added in front
55       of the list, and becomes itself the list head.
56       The type parameter can take six values :
57
58              TRANSN              for a N channel transistor
59
60              TRANSP              for a P channel transistor
61
62              TRANSN_FAST         for a high speed N channel transistor
63
64              TRANSP_FAST         for a high speed P channel transistor
65
66              TRANSN_HVIO         for a low leakage N channel transistor
67
68              TRANSP_HVIO         for a low leakage P channel transistor
69
70       The x, y, width , length, ps, pd, xs and xd,   arguments  fill  respec‐
71       tivly the X, Y, WIDTH, LENGTH, PS, PD, XS and XD fields.
72       Four  connectors  are  created each time a transistor is added, and the
73       ptgrid, ptsource, ptdrain and ptbulk losigs are  attached  to  the  SIG
74       field  of  the locon of the appropriate connector. The connectors names
75       are grid, source, drain and bulk, their direction, DIR, are set to 'T',
76       and  their  TYPE INTERNAL.  For details on the structures, see locon(3)
77       and lotrs(3).
78

RETURN VALUE

80       addlotrs returns a pointer to the newly created transistor.
81

ERRORS

83       "∗∗∗ mbk error ∗∗∗ illegal transistor type : type"
84              The type is not a legal transistor type.
