can't edit value of CDF parameters in Edit Object Property form

Nhumai

Hi 

I have a capacitance symbol and I need to edit  the capacitance value of that symbol.  I do "q" to bring up the Edit Object Property form and try to enter the value. 

However, I can't edit any value in that form. What would be the potential problem here ? how I can enable editable for those CDF parameters ? 

thanks

    Hi Nhumai,

    Can you post a screen grab of the form so it’s clearer what the issue looks like? After all, a picture is worth a thousand words!

    Regards,

    Andrew

    Hi Andrew, 

    I include 2 pictures. First one is the one I have a problem to edit the value of parameters. The second one is the normal one.  You can see that I can't click on any button in the first picture so I can't edit any parameter value. Please help 

    thanks

    Hi Nhumai,

    This is probably something you should consult whoever provided this technology, because it's almost certainly a function of their PDK. 

    You can check in the CDF (Tools->CDF->Edit in the CIW) for the ca18_rcx/csmimw4 component, and for each of the parameters that you expect to be editable, check the editable callback. Presumably each is returning nil and hence the fields are not editable. You might want to compare it with the other component, ca18/csmim4 (different lib and cell name) to see if there's a difference. What is correct, I can't say as this requires knowledge of this specific PDK.

    Regards,

    Andrew.
