Hi, I have run transient analysis in ADEL and the data points taken for the signal are too many, 500 kB of data generated for 3us of transient analysis. How to reduce this points taken by ADEL? Because if I run it for 1 second this would need 166367 GB. Is ridiculous.
 

What simulator do you use ?
Show me netlist fragments regarding analysis and option settings.

Hi, Attached you can find the netlist, which is a ring oscilator. The option settings for the transient analysis in ADEL Cadence. And the data generated when downloaded in .CSV file. Is important to say that this amount of data is required by cadence in order to run the simulation and if I increase the transient time also the space goes up.

There is no simulator whose name is ADEL.

Understand things correctly, before posting.
Can you understand netlist surely ?

Show me simulator name and netlist.

Sorry. Attached you can find the netlist, including the name of the simulator, spectre. **broken link removed**
 

"keep all" / "save all" collects a ton of data that you
probably do not care about. You can save only the
explicitly-cared-about vectors.

If you only care about the last N cycles of that 1-second
run. then you can start data saving late, at a point of
your choosing. I don't recall the syntax but I think it's
there in the transient run settings pop-up.

Maybe it's not the simulator that's "ridiculous", but rather
the idea that a few million time-axis points for every
nore and branch is really all and entirely useful.
