Document Table of Contents Non-Segmented Buffer

The non-segmented buffer is the default buffer type in the Signal Tap logic analyzer.

At runtime, the logic analyzer stores data in the buffer until the buffer fills up. From that point on, new data overwrites the oldest data, until a specific trigger event occurs. The amount of data the buffer captures after the trigger event depends on the Trigger position setting:

  • To capture more data from before the trigger occurs, select Post trigger position from the list.
  • To capture all data from after the trigger occurs, select Pre trigger position.
  • To center the trigger position in the data, select Center trigger position.

Alternatively, use the custom State-based triggering flow to define a custom trigger position within the capture buffer.
