AMD-640 Chipset I/O Model
21340A/0—April 1997
IBIS Models
AMD provides models of the AMD-640 system controller and
the AMD-645 peripheral bus controller I/O buffers for system
designers to use in board-level simulations. These I/O buffer
models conform to the
I/O Buffer Information Specification
(IBIS), Version 2.1
.
I/O buffer models represent the characteristics of the drive
strength configuration supported by the AMD-640 chipset. The
model also associates the appropriate driver type to its
respective pin. In the AMD-640 system controller, the memory
drivers are programmable by configuration registers. Hence
the designer must select the 12ma or 24ma driver, depending
on the intended use.
Each I/O model contains voltage versus current (V/I) and
voltage versus time (V/T) data tables for accurate modeling of
I/O buffer behavior.
The following list summarizes the properties of each I/O buffer
model:
I
All data tables contain minimum, typical, and maximum
values to allow for worst-case, typical, and best-case
simulations, respectively.
The pullup, pulldown, power clamp, and ground clamp
device V/I tables contain enough data points to accurately
represent the nonlinear nature of the V/I curves. In
addition, the voltage ranges provided in these tables extend
beyond the normal operating range of the AMD-640 chipset
for those simulators that yield more accurate results based
on this wider range.
Rising and falling ramp rates are specified.
The min/typ/max V
CC3
operating range is specified as 3.135
V, 3.3 V, and 3.465 V, respectively.
V
il
= 0.8 V, V
ih
= 2.0 V, and V
meas
= 1.5 V.
The R/L/C of the package is modeled.
The capacitance of the silicon die is modeled.
The model assumes 0 capacitance, resistance, inductance,
and voltage in the test load.
