First of all, I apologize for a delayed answer - I was out of office for a couple of days.
Thank you very much for your advices and explanations. I tried to follow your instructions on running the qpss HB analysis - with the same output: Insuficient memory.
What I am working on is a purely academic project, so I don't have a problem sharing the log files - I just want to have it running.
Here is the line about the software version:
spectre (ver. 126.96.36.199508 -- 15 Dec 2008).
Here are some warning that might be interesting, and I couldn't get the hang of them:
qpss: `flexbalance' is not a valid parameter for an instance of `qpss'.
qpss: `oversample' is not a valid parameter for an instance of `qpss'.
Namely, for some reason it doesn't like the oversample to be 1 - and I read here that it should be 1... Flexbalance, I couldn't find - what is it?
Here is the circuit inventory:
ahdl simulator 1
This number of almost 250k equations looks really scary... But, as I mentioned a couple of posts ago, it's what I get after QRC extraction. I tried sett ing the parasitics limit to higher values (so I have less parasitics) but then the results start to change and look much better than when all of the small ones are included. So, I guess I don't have a choice here, it must be this much... Right?
Also, please find attached the screenshot of my qpss analysis. Am I doig it the right way?
Thank you very much for you effort.
