DDR Pro Advanced Technology

1. XILINX Virtex II Pro controller featuring our improved high-speed DDR test engine. 2. Vtt generator for true STTL-2 testing. 3. Advanced analog section for measuring module's current, voltages and the board's temperature. 4. Digitally-controlled high resolution VDD regulator. 5. 200-533MHz DDR clock generator.

RAMCHECK DDR Pro Features Basic Test screen shows the size, the speed, the voltage, the test pattern, the module's bank and the CAS Latency. This example shows testing at 466MHz. (533MHz testing will be available within a few months.) Users can set up the frequency, the test voltage and the CAS LATENCY either through setup or CHANGE-ON-THE-FLY. This example shows a module that was setup to run at 500MHz and at 2.90V. Setup Parameters menu allows the user to setup the Frequency, the Voltage, the CAS LATENCY, the Refresh rate and much more. These setup values remain in effect until changed by the user. Each parameter has a default value that can be reset by the user. Expanded CHANGE-ON-THE-FLY can be used to setup the Frequency, the Voltage, the CAS LATENCY and the Refresh rate only for the current test. Following test, it returns to the current setup parameters. The DDR PRO allows you to set up the CAS LATENCY. This screen shows our default setup which allows the test program to selected CL=2 or CL=2.5 during each test phase. In this example, the CAS LATENCY was fixed to CL=2.5 throughout the tests. The new DDR PRO VDD Voltage setup allows the user to change on-the-fly the test voltage in the range 2.2V-3.0V. When set to AUTO, RAMCHECK automatically tests the module at 2.5V/2.7V. Unlike the CHANGE-ON-THE-FLY above where the new voltage setup is effective for one test, you can use the Setup Parameters to change the test voltage parameters for all tests. RAMCHECK Basic Test provides several screens for test result. The third structure screen shown here includes some of the new features of the DDR PRO, including the CAS LATENCY and the voltage setup. Here is another example where the CAS LATENCY was set at CL3 ONLY and the voltage left at automatic mode (2.5V for modules running up to 333MHz, 2.7V for higher speed modules). RAMCHECK's built in test log shows the actual voltage of the test. CAS LATENCY override is shown in the Test Log. In this example, the module is tested at CL=3 only. In the automatic (default) mode, the CAS LATENCY is changed between CL=2 and CL=2.5

If you need a test solution for non-standard or proprietary memory, the DDR Pro's advanced technology also makes it much easier to build customized adapters and converters. Current users of the older RAMCHECK DDR adapter (p/n INN-8668-6) may also convert their existing adapter to the RAMCHECK DDR Pro level at a substantial savings.
