Ocean: Save waveforms to .png

coco009

Hi,

 

I have a quick question and would be very grateful for some help.

 

I have an ocean script testbench, which is creating various plots. At the end of the run, I wish to save the resulting waveforms. Currently, I have to manually go: 'File' -> 'Save as image' on the waveform window. Could somebody please inform me how to do this within ocean, i.e as a script so that I can automate this? Any help would be greatly appreciated.

 

 

Regards

  •  After plotting use the hardCopy function: 

    hardCopyOptions(?hcOutputFile "myGraph.png")
    hardCopy()

  • Dear Samir,

     

    Thanks for your very prompt reply. I knew it had to be something simple. I currently cant get it quite to work though, as I dont appear to have .cdsplotinit file. I have copied a sample file into the same locations as my .cdsinit file, but when plotting, I keep getting the error that there were no .cdsplotinit files found.

     

    Do you (or anyone else) know how to set up the .cdsplotinit file so that it will be picked up when I run the ocean script?

     

     

    Thanks very much again

     

    Regards

  • Hi again,

     

    Following on from my previous post, I have actually found that all I have to do is drop the .cdsplotinit file into my home directory and that works fine in that I am no longer warned that the file cant be found and it loads the one in my home directory.

     

    The problem now is that although the printing to file appears to have taken place ... no warnings/errors, there is no resulting .png file.

     

    Anybody have any thoughts? Is there something specific required within the .cdsplotinit file to perform the plotting of the .png?

     

     

     

    Thanks in advance

  • Hi, I'm new.

    I wrote a new post yesterday but I can't find it in forum until now so I write it here.

    I have similar question  of command "hardCopy".

    I wonder why I can't find the graph in the folder "zzz" after I set  hardCopyOptions(?hcTmpDir "/aaa/yyy/zzz") .

    I only can get the graph when I set  hardCopyOptions(?hcTmpDir "/aaa") .

    At first I think it  must be in root folder, but  I also can't get the graph when I set  hardCopyOptions(?hcTmpDir "/bbb") .

    Is there some requirement to the directory ?

  • Is it possible to plot waveforms to a "virtual" waveform window and then capture that window to a JPG or PNG? That would be useful for batch mode.

  • Seems like

    > ocean -nograph

    makes this possible..
