Bug or Not? HB analysis aborted abnormally when "memory usage estimation" is on

MarcoL

Hi all,

        It's me again. Maybe I enjoy posting things here, especially when working overtimes on such a lovely weekend. 

        Last week I was informed that there is an "memory usage estimation" option in HB analysis. Maybe useful as I thought, I turned on it. Yes, there were several lines in the output log about the possible memory usage. Good. But guess what happened next. Nothing! Spectre was aborted without any error information after the memory usage estimation and the information how long it had taken. Seemed like it thought it had done its job successfully, though actually it did nothing in HB. 

       Funny thing is spectre came back to the normal way after  the memory usage estimation was disabled. That's all I did. So I thought maybe there is a bug in spectre.

      Almost forgot to mention that I am using IC6.1.6-64b.500.10 and spectre 15.1.0.345.isr2. 

Regards

Marco

    I didn't find any specific reports of a problem, but then again the memory estimation feature for harmonic balance was relatively new at that stage (it was added in an MMSIM14.1 ISR). What I'd suggest is you try with the latest MMSIM15.1 hotfix (the one you have is quite old) and/or the SPECTRE16.1 base release (recently out); if it still is a problem, contact customer support (nothing will get fixed by reporting it in the community forums, and almost certainly this will need a testcase as otherwise it would happen all the time and it would be more likely that we'd seen it).

    Regards,

    Andrew.
