Hide text fields I don't need in parameters section

Jorge Rdz

Good day to everyone,

I'm new in this funny world of Skill and I have a problem at the moment of display/hide parameters of a Pcell.

I have a power grid Pcell that has 7 metals (from M4 to M10) and I'm able to select differents parameters like power grid domains (VDD, VSS, VDDREG), width, pitch etc.

To select the top and bottom metal, I have two cyclic, so I can have a power grid connected from M4 to M10, and with text field to write the width, pitch and power domain of every "finger" in each metal. My problem is that I can't hide the text field that I don't need. For example, in case my power grid is from M8 to M10, I just need to display the text fields of M8, M9 and M10 and nothing else. 

Do I need a callback to make this? 

Can I use a list of my main procedure in the CDF file? How Can I use it?

Thanks for the help and your time, 

Jorge

  • Hi Jorge,

    You probably need to specify a display callback in the CDF for the parameters you wish to display some of the time and not others. This could be something like:

    cdfgData->topMetal->value=="M10"

    This would be in the display callback for the M10 field, and dependent upon whatever the topMetal parameter is called.

    I don't know what you mean by "Can I use a list of my main procedure in the CDF file?"

    Regards,

    Hi Andrew, 

    Thank you for answering.

    Sorry with the last part. I will explain myself better.

    I have 3 files:

    • One where I have the main program, in which I make the calculations of width, pitch, number of vias, etc.
    • The second is the CDF file where I have defined the objects I will need.
    • The third is where I put the default value of my parameters.

    So, in my first file, I have a condition that check the topMetal and BotMetal, select the metals that are between those two "limits" and then it include them in a list, these are the metals that I will use. My plan is to use that list in the CDF file to compare if the text field of each metal is in the list and then display it or not.

    In fact I can compare only with one limit, the top or the bottom metal. 

    Can you give me an example of how to trigger the callback? 

    Thanks,

    Jorge
