How to plot all corners using ocean xl?

Reinice

Hi Andrew,

Good Day.

I have an ocean script that executes all corners that have been set up. Problem is that the last corner run is the one only plotted everytime I execute it. Theres no issue on the corners, only in plotting. Here's the function/s I used for plotting:

First used to plot corners:

plot(

getData("/AVDD33")

getData("/BGOUT")

)

Second used to plot corners:

nets = list("/AVDD33" "BGOUT")

let( (waves)

waves = foreach(mapcar net nets v(net))

awvPlotWaveform(

newWindow()

waves

?expr nets

)

)

Thanks and Regards,

Reinice

  • Hi Andrew,

    I think I've already resolved this issue. But I' am not sure if my analysis is correct.

    I think it's the corner combination of my script. Before I have the same value for all "variable"

    ocnxlCorner("corner1"

    '( 

    ("variable" "temperature" "-40")

    ("variable" "AVDD" "3.3")

    ("variable" "Cload" "2p")

    ("modelGroup" "\"top_ss"")

    ))

    ocnxlCorner("corner2"

    '( 

    ("variable" "temperature" "-40")

    ("variable" "AVDD" "3.3")

    ("variable" "Cload" "2p")

    ("modelGroup" "\"top_tt"")

    ))

    ocnxlCorner("corner3"

    '( 

    ("variable" "temperature" "-40")

    ("variable" "AVDD" "3.3")

    ("variable" "Cload" "2p")

    ("modelGroup" "\"top_ff"")

    ))

    and when I set up my "variable" like this

    ocnxlCorner("corner1"

    '( 

    ("variable" "temperature" "-40 25 125")

    ("variable" "AVDD" "2.97 3.3 3.63")

    ("variable" "Cload" "2p")

    ("modelGroup" "\"top_ss"")

    ))

    ocnxlCorner("corner2"

    '( 

    ("variable" "temperature" "-40 25 125")

    ("variable" "AVDD" "2.97 3.3 3.63")

    ("variable" "Cload" "2p")

    ("modelGroup" "\"top_tt"")

    ))

    ocnxlCorner("corner3"

    '( 

    ("variable" "temperature" "-40 25 125")

    ("variable" "AVDD" "2.97 3.3 3.63")

    ("variable" "Cload" "2p")

    ("modelGroup" "\"top_ff"")

    ))

    All corners have been plot out.

    Question now is why it did not plot all corners(only corner3) before even if "modelGroup" have different values?

    Thanks and Regards,

    Reinice
