ViVA crashes when loading a large group of simulation data

slim5

Hi,

  I have a group of PVT simulation data (~50 sets) and have been unsuccesful in creating a plot with ViVA. This problem can be attributed to the fact that I have limited memory installed on my PC and my attempts had resulted in memory allocation error.

  At the moment, I have an ocean script that utilizes for-loop to go through each simulation data and plot the desired waveforms. What I noticed during the script execuation is that the child processes, java and virtuoso, will consume ever increasing memory with each plot command until all available memory are used up and the program will exit with the memory allocation error.

  Is it possible get java and virtuoso to release up the memory before OCEAN opens the next set of simulation data? What I am thinking is something like this: Open results -> plot results -> freeze graphc -> clear memory -> open next results and etc?

  Also, is it also possible to enable Fast Viewing Support in OCEAN with the hope that this step will result in lower memory requirement?

 I have IC6.1.4.500.12

Thanks

Slim

  •  Hi Andrew,

      I would try moving to IC615 to see if that version will help to alleviate the memory management.

      Is there a way to make sure that plotting with fastview is enable in OCEAN? I did envGetVal("spectre.outputs" "fastViewOption") and the system returned "t", however, I still find the plotting to be very slow.Thanks!
