From web version v6.0 to v7.1, the software itself crashes over 10 times on my computer every day, usually during synthesis or simulation. That depress me much. The reason make me think it's not my computer's problem is the software seems not well multi-threaded during working, often makes computer freeze for a short while. Does anyone suffer the same problem as me?

Quartus II 7.1 Web edition also crashes on my computer (but only sometimes[1 of 30 compilations]).

I use the commercial edition of 7.1, and I too experience the occasional temporary freeze. I don't often get crashes though, except with specific functionality. (For example, trying to disable specific HDL message numbers in the Settings menu crashes Quartus for me every time.) I can second your comment about the multi-threading, too. One particularly crazy thing I've noticed is that if I have nios2-terminal running then I sometimes have to exit it in order to start a new compile in Quartus, or else the compile doesn't proceed. Ridiculous!

In compilation process settings, change it back from 2 to 1 core used during the fitting, that might solve the issue.

Altera's engineer told me to turn off 'HyperThreading' of my Pentium 4 CPU, I will try that, maybe the Quartus II is not compatible with that stuff:)

The Quartus handbook does sound like the official recommendation is not to use it (see end of handbook quote below), but I suspect the restriction is really only for when you set "Maximum processors allowed for parallel compilation" to a number greater than 1. From the Quartus handbook, Volume 2, Section III, Chapter 8, under "Use Multiple Processors for Parallel Compilation": --- Quote Start --- Do not consider processors with Intel Hyper-Threading to be more than one processor. If you have a single processor with Intel Hyper-Threading enabled, you should set the number of processors to one. Altera recommends that you do not use the Intel Hyper-Threading feature for Quartus II compilations. --- Quote End ---

This is what a settings dialog looks like before a crash, software version is QII 7.1sp1.

It looks like a lack of memory,
is your machine using virtual memory at that moment ?

If yes, is there enough virtual memory ?

Yesterday was not a good day for QII software..
I've had a lot of internal error (5 different kind) and 3 fatal error too.
I've opened also the mysupport questions reporting all the errors.
Cause I've a Core2duo I've told QII to use 2 core and also 1 core but nothing changes..
If I've not used a lot of IP (that changed a lot in 7.1 versions) I'll return immediatly to v.6.0..

Here is the list of the Internal errors I've got.
Have a look also at IntError2 and 5.. they're error in same module and same line.. but.. 2 kind of different errors..
That discourage me a lot..

Hi Darkwave -

You might want to try running a RAM hardware diagnostic. You have found a completely incredible number of unique errors, mostly related to memory allocation / corrupt memory. One of my coworkers had that happen, turned out he had a bad DIMM.

I've thought the same and today my ex pc was given to informatic systems to check.
I hope that it depends by ram else I'll be in trouble here at work if I cannot compile and continue to work.
