Quartus II Internal Error with SignalTapII

All,

For further investigation in my current design i would like to use the signaltap II logic analyser. After creating and enabling a signaltab file (At first only 1Clock and 3 Nodes) with the SignalTab II Editor the stp1.stp file was added to the design but unfortunately the design can't be compiled anymore. During Analysis&Synthesis the following Error appears:

Quartus II Internal Error

*** Fatal Error: Access Violation at 0X009C4DF4

Module: quartus_map.exe

Stack Trace:

0x4DF4 : QTL_ZOFSTREAM::close + 0x34 (ccl_qtl)

0x55F25 : sgn_qic_helper + 0x4A2D5 (synth_sgn)

End-trace

HELP!!!

Dieter

Quartus II Software Version 9.0

    Such things happen. You should send a service request to Altera support. You can try to rebuild the design by deleting the db directory and, if the error persists, build a new Signal Tap file, possibly with slightly different signal nodes. The error may also be triggered by irregular properties of your design.

    Hello!

    I've found the problem. Working on the project over LAN caused the error. I had to copy the complete project on local pc.

    Apart from other possible problems, it's strongly recommended for performance reasons You easily get several millions of individual file accesses during a compilation run.
