Verify Device
The Verify Device command compares data in a programmed device
with data in RAM or in a disk file. Depending on which type of device is
selected, either the Verify Logic Device screen or the Verify Memory
Device screen appears when you select the Verify Device command.
Before you can verify a device, you need to load the data into RAM or
select a disk file as your data source. RAM data can be loaded from a
master device, from a disk file, or through the serial port.
Verify Logic Device
If you select a logic device and then select the Verify command,
UniSite-xpi’s Verify Logic Device screen appears.
To verify a logic device, follow these steps:
1. Select and socket a logic device.
2. Press E
NTER
to begin the verifying process.
3. When the verify operation is complete, UniSite-xpi displays the
following message in the message bar:
OPERATION COMPLETE. Sumcheck = xxxx (8-bit)
Optional Parameter
Screens
There are two types of parameter-entry screens: simple and complex.
UniSite-xpi defaults to displaying the simple, Non-default parameters
screen. If you want to view the complex, All Parameters screen, press F4
from the Non-default Parameters screen. If you have changed any of the
default parameters, those changed parameters will also show up on the
Non-default Parameters screen.
The following parameters are found on the complex, All Parameters
Verify Logic Device screen.
• Logic Verification (A,F,V)—Specifies the type of logic verification to
perform. Select from Fuse Verification F, Vector Verification V, or All
A
. Fuse Verification checks the fuse pattern programmed into the
device with the pattern in UniSite-xpi’s memory. Vector Verification
functionally tests the device, using structured test vectors stored in
memory. A directs UniSite-xpi to perform both fuse verification and
vector verification. Press S
PACE
to step through the three choices.
This parameter defaults to A.
