Traditional test systems provide the user with a variety of AC test patterns to use in their testing process. If a customer wanted the capability to generate a proprietary test pattern, they had to purchase a high-end automated test system. For most companies this is cost prohibitive and not a viable option.

Triad Spectrum, Inc. has once again listened to what the customers are saying and is proud to offer a new feature called "Script Code" in its new DDR3/2 test system, the TCIII-1200L. In this new system, the customer can use the script programming language to create a customized test pattern. Once the pattern is created, the "Script Code" pattern generator/ compiler is used to compile the code and then generate the new test pattern.

The "Script Code" function also serves as a powerful compiler/debug tool. It contains a built-in compiler and debugger for the "Script Code" programming which allows the customer to monitor the timing waveform of the programming algorithm as well as the timing bus transactions. This is all accomplished under the "Signal Tap" tool.

The new pattern is then imported into the test list and gives the customer a customized pattern with AC (tSU, tWD, tSAC, tRCD, tCL, tAL, tWR, tRP, tRC, tREF, tRFC, etc.) and DC (Vdd, Vref) parameters for testing their product. In addition to the above, the customer can also create a motherboard test pattern algorithm using the "Script Code" function.

The new TCIII-1200L performs the test pattern much faster than using a traditional motherboard test because there are no wait states in the operating system. Utilizing the "Script Code" function gives the customer a high degree of flexibility in terms of timing bus programming for creating unique Read and Write programmingtransactions under best and worse case AC parameters. This can also be used to create a no-wait state bus transaction in the Read to Write cycle.

Older model Triad Spectrum test systems provided a wide variety of AC test patterns but did not allow the user to generate a proprietary test pattern. The new TCIII-1200L offers the “Script Code” feature. This will let the end user program proprietary test patterns much like the more costly,high end ATE’s. Utilizing the script programming language, the customer can create a customized test pattern and then use the Script Code pattern generation compiler to compile and generate the new test pattern. The new pattern is then imported into the test list with AC (tSU, tWD, tSAC, tRCD, tCL, tAL, tWR,tRP, tRC, tREF, tRFC, etc) and DC (Vdd, Vref) parameters for customized testing.

The end user can also create motherboard test pattern algorithms, utilizing the Script Code function and then use this in addition to the programmable AC and DC parameters. Test patterns in the TCIII-1200L perform much faster than the stand alone Motherboard test because there are no "wait states" in the operating systems.

Script Code programming gives the end user a great deal of flexibility in programming the timing bus to create a unique Read and Write bus transaction under best and worst case AC parameters. In addition, a "no wait" state bus transaction can be created in the Read to Write cycle.

A built in compiler and debugger environment is in the Script Code programming. This allows the user to monitor the timing waveform of the programming algorithm and the timing bus transactions under the Signal Tap tool.
