A 100
Analog and Mixed-Signal Test System
Easy and Affordable Multi-Site Testing
Cogent ATE’s Leopard A Series Analog and Mixed-Signal Test System represents a
transformational change in the testing of analog and mixed-signal ICs, a high-volume and
cost-sensitive segment of semiconductor market where the test cost has become a
growing percentage and sometimes the most significant part of the overall cost of
manufacturing the device. Cogent ATE’s Leopard A Series Power Management Test
System will give our customers, Integrated Device Manufacturers (IDM), fables
semiconductor companies and Outsourced Assembly and Test (OSAT) significant cost
advantage over their competitions.
Cogent ATE’s strategy to reduce the cost-of-test is simple; higher throughput at a lower
price. We achieved higher throughputs with practical quad-site wafer and final testing
using Cogent ATE’s Floating Test Sites™ System Architecture. We designed our test
system for low cost by using the latest electronics and by incorporating our proprietary
embedded IP core technology, Tester-on-a-chip™, in our hardware.

Reliable and Repeatable Test Results by Design
Reliable and repeatable multi-site testing requires floating resources with independent ground
True parallel multi-site testing
connections to avoid interference commonly associated with a common ground pathway.
with Floating Quad-Site Testing
architecture Cogent ATE’s Floating Test Sites™ (FTS) System Architecture provides electrical separation
between individual test sites in automatic test equipment (ATE) by providing floating resources with
Scale from Single to Multi-Site independent ground connections for each individual device under test (DUT) sites. This feature allows
Testing automatically with Auto each device’s test results to remain isolated from the test results of other adjacent sites. This leads to
Test Replication better test accuracies and fewer false rejects due to device-to-device interference errors.
48 Analog Channels and 32 In Automatic Test Equipment (ATE), the best path is the shortest path. All resources reside in the
Digital Channels in a single test test head. An included full-featured manipulator then that brings the test head as close to the
head Device-Under-Test （DUT）as possible for both wafer level and final test configurations.
Standard full feature Guaranteed Multi-Site Testing
manipulator for wafer level and Cogent ATE’s Automatic Test Replication™ (ATR) Technology allows a test solution to be scaled
final test from single to multi-site with ease, i.e. with a click of button and without any risk. This technology
eliminates the long and tedious routine of copying a single site test program, modifying it for
SBC Industrial PC, Telescope multi-site testing and then debugging the new test program. Since all of our analog and digital
mounting for Monitor and resource boards are Floating Quad-Site Testing™ ready, which means that the success of
conversion from single to multi-site testing will not be left to chance, i.e. the skills of the test
Keyboard on the manipulator
engineer or the availability of floating resources. Our multi-site test solution are guaranteed to work
for a compact and ergonomic
since each individual test sites are running on identical sets of hardware that are electrically isolated
test cell from each other.
Wide Range of Target Devices
By choosing from a wide range of resources, the Leopard A Series can test devices from several
high-volume IC markets, such op-amps, MOSFETs, Power Management Devices, ADC, DAC and
Audio CODEC.
