                     Next-Generation SoC Devices  
  FREMONT, Calif., March 6 /PRNewswire-FirstCall/ -- 
Credence Systems Corporation (Nasdaq: CMOS), a leading provider of test 
solutions from design-to-production for the worldwide semiconductor industry, 
today announced that Cirrus Logic, Inc. (Nasdaq: CRUS) has selected the 
Quartet(TM) Series to test multi-media communication devices, including DVD 
controllers for next-generation, high-end audio and video products.  By 
utilizing the Quartet, Cirrus Logic will be able to reduce its overall test 
costs for complex system-on-chip (SoC) designs.  
The Quartet Series was chosen by Cirrus Logic as part of their strategy to 
increase test capability and efficiency, ultimately bringing devices to market 
faster and at a lower cost. The large installed base of the Quartet worldwide 
provides Cirrus Logic with a fast, seamless transfer of complete test 
requirements from the design engineering facility to independent foundries and 
subcontractors worldwide. Using the Quartet platform for design and production 
test requirements reduces overall costs, complexity and time required for test 
program development.  
"With industry pressures to bring products to market quickly, it is 
imperative to utilize an integrated and efficient test platform, which 
Credence provides us through their Quartet Series of testers and emulation 
software," said Jerry Gray, Vice President, World Wide Operations, Cirrus 
Logic. "As we continue to develop high-performance solutions to meet the 
growing demands of the consumer electronics industry, we looked for a system 
that would best be able to meet the test needs of devices with next-generation 
communications technologies.  Cirrus Logic found that the Quartet offers the 
kind of innovative technology we need to deliver consistent quality to our 
customers.  This choice was further complemented by Credence's demonstrated 
technical Field Applications experience, tremendous overall cost advantage 
offshore and capability to support systems worldwide."  
"We're pleased that Cirrus Logic, a leader of the digital entertainment 
revolution, has selected the Quartet as its SoC test platform, reflecting the 
performance, accuracy and flexibility of the system," said Ed Wagner, General 
Manager of Credence's Consumer Mixed-Signal (CMS) Division.  "With Quartet's 
large installed base in foundries and test houses, many of our fabless 
customers have realized the benefits of standardizing on this test platform. 
Being the only ATE vendor to offer the most complete design-to-test solution 
makes us a natural choice for companies such as Cirrus Logic that are looking 
to enhance their production flow from the design phase through to production
