2003-12-30 Paolo Nenzi <p.nenzi@ieee.org>
* src/spicelib/devices/hfet1/*: Added parallel multiplier and "dtemp" to
the code. Added the pole-zero analysis and parallel code checks.
Corrected a bug in the unsetup function that caused a segfault.
* tests/hfet/, tests/hfet/id_vgs.cir, tests/inverter.cir: added hfet
test netlists.
* DEVICES: updated hfet1 status.
