Compuware Enhances Device Driver Development Suite

Compuware DriverStudio 3.1 Now Offers Full Support for Microsoft Visual Studio .NET 2003; New DriverWizard Creates Windows Device Drivers in the C Programming Language

DETROIT--January 21, 2004--Compuware Corporation (NASDAQ: CPWR) today announced the general availability of Compuware DriverStudio 3.1, a suite of tools that accelerates the driver development life cycle and promotes the development of high-quality Windows device drivers. DriverStudio 3.1 helps device driver developers write, debug, test and tune high-quality driver code that meet the strict quality standards for Windows Hardware Quality Labs (WHQL) certification to ensure device driver quality.

DriverStudio 3.1 now offers integration with Microsoft Visual Studio .NET 2003, including side-by-side operation with Visual Studio .NET 2002 while maintaining full compatibility with the Microsoft DDK, making device driver development faster and easier.

Logitech (NASDAQ: LOGI) www.logitech.com, a market leader in personal interface products for the digital world, has been using Compuware DriverStudio products for years to create and maintain drivers for their mice, keyboards, cameras and game controllers.

"Our development teams find the DriverStudio suite to be effective, efficient and highly reliable," said Fred Swan, Marketing Director of the Interactive Entertainment Business Unit at Logitech. "The object-oriented structure and wizard functionality of DriverStudio allows us to create drivers three times faster than we could with traditional driver development tools. And, by setting breakpoints, we can also quickly and easily find any problems in our code. DriverStudio enables us to rapidly create 64-bit drivers for our game controllers. The Visual SoftICE UI and the ability to remotely debug AMD64 systems over a network are just two features of DriverStudio 3.1 that really make this new version exciting to us."

The C and C++ programming languages are the primary languages developers use to write device drivers. To support developers’ needs, the DriverWorks and DriverNetworks components in DriverStudio 3.1 now offer a new DriverWizard that lets developers build Windows device drivers in either C or C++ programming languages.

DriverStudio 3.1 also offers expanded platform support. Visual SoftICE now offers full support to debug device drivers and applications on AMD’s 64-bit Opteron and Athlon64 processors. Also, SoftICE now supports VMware 4.0.

Also new in DriverStudio 3.1, BoundsChecker Driver Edition now allows users to change their configuration settings without having to reboot. This feature can be turned on or off using checkboxes in the "Settings" dialog box, making device driver development easier.

TrueTime Driver Edition has been enhanced giving users the capability to merge two or more instrumentation files into a single file and compare performance data against previous profiling sessions to validate any changes to the code. Also, data from system performance counters can now be collected providing developers with more detailed and precise information. Additionally, TrueTime Driver Edition’s new "Custom Chart" provides an integrated, customizable display of all function, IRP and performance data. This gives developers the capability to monitor and display information from performance counters.

"Device driver quality plays a critical role to the successful market delivery of device drivers. So providing driver developers with reliable driver development tools is key," said John Carpenter, Product Manager for Compuware DriverStudio. "DriverStudio 3.1 accelerates the development, debugging, testing, tuning and deployment of device drivers and helps driver developers create better WHQL-certified device drivers faster and easier."

DriverStudio 3.1 is currently shipping at a U.S. price of $2,499.
