Intel System Trace fall

Hi,

We are using Intel System Trace to trace hardware signals (ODLA, VISA) for modern SOCs and PCHs. We've found a bug in Trace Decode Library (TDE) of the System Trace Tool: when MIPI STP data from ODLA contain the Global Trigger signal in active state, MIPI packets decoder encounters the following exception:

Error: An exception was encountered during the execution of
    decoder instance: mipi
    Engine Null Pointer Exception:
location: NPK::EngineHandle::getChannelRecord
     line: 63
variable: d_rec

We can send extended NPK API log if we need it to resolve the problem.

We've started observing the problem from Intel System Studio Update 1 (2018.1.051) version. The previous (2018.0.040) version of System Studio doesn't contain the error and perfectly displays the Trigger in VCD output

Hi Mark,

Hi Mark,

what's the target platform / decode use-case combination on which you're seeing the issue? If you can share the input STP data that'd be perfect, but the API and TDE logs will also help.
