Functional Testing for Memory

This is an algorithm IP that verifies the operation of IC Memory functions.
It applies a pattern to measurement target and compares the output signal and the expected value and judge Pass/Fail. This IP is aimed at confirming logic operation of IC Memory.

Actual use case is shown below.

  • Confirm logical operation.
  • Grade screening Test.
  • Operating margine Test.
  • Evaluation and analysis of the defective cells.

The revision history was integrated.

Output Raw Fail Address Memory_TypeF Lincense (PCXA01-M3005)

  • Error occurred when saving fail address file with setting the fail capture pins of the fail capture tab to 9 or more pins.
  • Error occurred, if saving fail address file when “Address Fail bit = 1”.

After improvement, these errors do not occur.
The revision history was integrated.

High Resolution Timing Setting for Memory_TypeF Lisence (PCXA01-M3006)

  • There was a case that Error occurred when Flow was executed.

After improvement, this errors does not occur.
The revision history was integrated.

Timing Search for Memory_TypeF Lisence (PCXA01-M3007)

Only the last measured value was saved in a variable, but after improvement, all measured values are saved in a variable.
The revision history was integrated.

Please refer to Revision History for other details.
