Test Conditions
The test conditions and the allowed commands are listed in the following
tables.
Note: C, K, U, and D are clock functions that allow setup time.
Vector
Symbol
Description
0
Drives the specified input pin low.
1
Drives the specified input pin high.
2-9
Super-voltages, defined by the device’s manufacturer.
B
Buried register preload.
C
Drives the specified input with a sequence of logic states: in
this case low, high, and low (high clock).
D
A single transition that drives the specified input low using
a fast slew rate.
F
Specifies that a particular input or output pin is to be
floated (tri-stated).
H
Verifies that the specified output pin is high.
K
Drives the specified input with a sequence of logic states: in
this case high, low, and high (low clock).
L
Verifies that the specified output pin is low.
N
Specifies that a particular input or output pin is floating
(tri-stated). UniSite-xpi’s F and N conditions perform the
same function.
P
Identifies a preload vector and invokes a preload algorithm.
This character is allowed on the clock pin ONLY; otherwise
it is treated as an X.
U
A single transition that drives the specified input high using
fast slew rate; equivalent to C without returning to the low
state. If more than 16 Ds or Us are used in any one test
vector, the extra Ds or Us are ignored during test.
X
Ignores the state of an output pin. UniSite-xpi applies a logic
level specified by a JEDEC file. X field value (1 or 0) or a low
is used as the default value.
Z
Verifies the specified input or output pin has high
impedance. UniSite-xpi will toggle the pin using a small
current during this test.
