Forum Post: Waveforms opened from Assembler not garbage-collected properly?
I have an ADE Assembler bench that runs across a few modes and corners, saving some waveforms. I tried writing a script to generate and export plots after the sim is done. The script works fine, but...

Hi Naci, Please contact customer support . Trying to debug performance issues is likely to be almost impossible via the forums. It's unlikely to be leafValue that's the issue here - but I think...

Naci, You wouldn't normally have an output expression using leafValue in the outputs - normal outputs are evaluated per sweep point, and so the leafValue won't work at simulation time because the...

Thanks ShawnLogan for your reply Actually I tried Harmonic Balance with oversample factor 8 and the user guide says that'd make it appropriate for square wave signals, but I also tried pss with...

OK, first of all, if you have a divide by 10, then it's important to be sure that this is not achieved by other division ratio and that the lowest frequency in the circuit truly is 4.5G/10 - if there's...

I'm not sure why you would use leafValue() to do this. Wouldn't the VAR() function suffice? Andrew
View ArticleForum Post: RE: Waveforms opened from Assembler not garbage-collected properly?
It's not quite as simple as garbage collection of the variables triggering this. There's some caching of waveform data to avoid re-reading the waveforms from disk, and the actual waveform object itself...

Hello Andrew, Thank you for your answer. I forgot to mention that I do calculations with the type set to sweep, so that they are calculated once all the simulations are done. I will contact the support...
View ArticleForum Post: RE: Accessing design variables in parametric set sweeps
Hi Andrew, I need to use the design variable in calculations in the output setup with the type set to sweep. So, when I use VAR() in such a case, it returns a vector with the same design variable value...

Thanks a lot, Andrew I'm checking all the notes you mentioned, but do I have to use ports at my I/O ports? it's a freq divider so I figured I only need a pulse source and the next stage's loading in my...
View ArticleForum Post: RE: Harmonic Balance Convergence Issue
There's no requirement to use ports with hb or pss analysis. The only reason to use ports is if you: Want to have source or a load with a built-in impedance similar to a probe in the lab, or for...
View ArticleForum Post: RE: Harmonic Balance Convergence Issue
well I don't know but I tried up to 130 harmonics now with shooting and I traced the internal nodes and found no signal with freq<4.5G/10. It's a FF-based divider so it's not expected to generate...
