Hi everyone,

I compile a code in QuartusII and during the last task (EDA Netlist Writer) this error occur:
------------------------------------------------------------------------------------------
Internal Error: Sub-system: WSC, File: /quartus/neto/wsc/wsc_port.cpp, Line: 514
m_port_info.num_of_dimensions() == 1
Stack Trace:
0x251D8 : WSC_PORT::bus_member_index + 0x88 (NETO_WSC)

End-trace

Quartus II Version 8.1 Build 163 10/28/2008 SJ Web Edition
-------------------------------------------------------------------------------------------

It's this error occur because of my QuartusII cannot support the compilation? Can anyone help me please..:sad:
Many thanks

Quartus II Version 8.1 Build 163 10/28/2008 SJ Web Edition

you are using an old version, why don't you download the latest version and see if it solves your problem, I'm sure that you will get more enhancements too in the new version, Quartus II is currently in version 11

As said, the problem may be solved in a recent version. I understand, that the error is observed while writing an optional EDA netlist. In other words, the compilation itself is O.K.?

My observation is, that unexpected compiler behaviour is often invoked by dubious design constructs that slip through the front end code check.
 
Thanks everyone. I appreciate your helps.
