| Give the spice type.  Allowable values are hspice, pspice, spice2,
| spice3 and spectre.
|
[Spice type]		spice2
[Spice command] "spice3  -tmp /tmp -init /dev/null %s %s /dev/null >%s 2>&1"

|
| Now specify some global parameters. These parameters will apply to
| _all_ the models in this file.
|
| Note on the [Temperature range] keyword: Since this is a CMOS circuit,
| the min column contains the highest temperature, since this temperature
| causes or amplifies the "min" (slow, weak) behavior, while the max
| column contains the lowest temperature, since this temperature causes or
| amplifies the "max" (fast, strong) behavior.  If this were a bipolar
| circuit, these temperature values would be reversed.

|
| Specify the SPICE file where the circuit is located.
|
| ST made high in the SPICE netlist
|
|
[Spice file] UBT062.spi

|
| Now specify the pin list.  Since we're just creating an IBIS file for
| the driver, we'll use a very short pin list.
|
| The pin list formats can be found in doc/s2ibis2.txt.  Briefly, the
| first line of each pin is of the form
|
|  pin_name  spice_node  signal_name  model_name
|
| If a pin description has more than one line (e.g. the first pin in the
| pin list below), the second line is of the form
|
| -> input_pin  enable_pin
|
| Note that the second line must begin with the symbol "->".
[Pin]
Y Y3 Y tristate_driver 
-> A GZ
A A A dummy
GZ GZ GZ dummy
VDDS VDDS VDDS POWER 
VSSS VSSS VSSS GND

|
| Now we give the particulars of the model "tristate_driver".  It is of 
| type "3-State" (allowable types may be found in doc/s2ibis2.txt) and is
| non-inverting. We want to use models from the file "spectre.mod" for
| typ, min and max simulations, and we want to include both a rising and
| falling waveform in our IBIS model. Both the rising and falling
| wveforms have a 500 ohm load; the rising waveform has the load
| grounded, while the falling waveform has the load connected to 3.3V.
| Neither waveform includes any other test fixture or package parasitics.
