Hi all,
Recently, we try to generate a bigger waveform file (in *.bin format) for purpose of Baseband Studio Playback by using ADS Ptolemy. We find it will apprear the message as below when the output file size up to 1.74GB every time.
******************************************
***** Abnormal Simulator Termination *****
******************************************
The simulator has unexpectedly terminated.
Could anyone give us any solution/suggestion about this....
BTW, it can work properly when the file size not so big.........
Regards,
Tigra Chien

We run ADS on Windows-2000 SP4. And our PC equipments are as bleow....
CPU : Intel Pentium-4 3.2GHz
Memory: 3GB DDR-400 RAM
HD : 2 x 200GB (C:\ 20G, D:\ 166G, E:\ 186G)
ADS are installed on C:\, but our working direction are set on D:\.........

If you can share your designs with us then we can investigate what is causing the problem. You should contact Tech Support and they will coordinate with you and R&D to resolve the issue.
Kostas.
Start ADS as
ads -d c:\daemon.log
You can use any other filename instead of c:\daemon.log. This file does not need to exist. It will be created.
What this will do is that it will create a STDERR window, where you can see all sorts of debugging messages. It will also save all these messages to the filename you specified. Most of these messages will not make sense to you but if indeed the system runs out of memory, you should see a message like the one shown below (where XXXX is some number).
hpeesofsim(XXXX): ... Process hpeesofsim (XXXX) has died.
hpeesofsim: out of memory!
Can you please try this and let me know what your findings are?
Thanks for your reply. Actually, we had contacted with Agilent Tech Support last week, but still not found what's wrong with this problem. Even we tried to use a simple block as following:
Source ==> Signal Converter ==> Sink
SineGen==>FloatToCx==>CM_BB_StudioStreamWrite
And NumricPoints up to 6x10^8 .......
BTW, we will try the debugging messages that you mentioned later .....
Does it cause by " Virtual memory" set-up ????

After tried the error messges display, the following are the result:
Message from hpeesofsim to hpeesofsess
Sending :0001741524@ctpc0304 1404@ctpc0304 DATA : ... 141 binary chars

... Close in=340, out=332, err=328.
... Found dead channel to check.

Sending :000042324@ctpc0304 1404@ctpc0304 SRVR_ERR 1 died:
It's really caused by "out-of-memory". What should we do in the next step ???

Design 1 (generating the file)
--------
SineGen ==> FloatToCx ==> CM_BB_StudioStreamWrite
where Start and Stop in CM_BB_StudioStreamWrite are set so that 6x10^8 data points are written in the file.
Design 2 (reading the file; runs out of memory)
--------
CM_BB_StudioStreamRead ==> Sink
(I assumed the Source mention in your response was CM_BB_StudioStreamRead).
then we should be able to reproduce this problem here.
What ADS version are you using?
Yes, our design is as the "Desing 1" (generating the file). And the error message appears in this stage. BTW, we use ADS2005A version......
Thanks........
