Quartus 25.1std | Signal Tap Crash

Hi Ryan,
 

Thank you for the details and the crash log.

The stack points to a Signal Tap acquisition-path failure (sld_chi / construct_load_data) when Run Analysis starts. A few quick checks should help isolate this:

  1. Please confirm compile, program, and Signal Tap are all done in Quartus Prime 25.1 Standard (avoid mixing with 21.1 SOF/tools).
  2. If Power-Up Trigger is enabled, please disable it, recompile, reprogram, and try Run Analysis again.
  3. As dandanlau suggested: remove the current .stp, run Project → Clean Project, create a new STP with 1–2 simple signals and a valid acquisition clock, then retest.

Regarding Windows 11 vs “Windows 10” in the log: Quartus often reports Windows 10 on Windows 11 systems; that alone is not the cause.

If it still crashes with a fresh minimal STP (Power-Up Trigger off), please share:

  • Whether Power-Up Trigger was used
  • Cyclone V OPN / cable type
  • Project archive (.qar) including .stp and the crash report

 

Best regards,
Fakhrul
