Problems with: drLoadDrf("~/GHzT/display.drf" nil)

Magistus

 

Hi,

I want to automatically load my display.drf file. I added the line

drLoadDrf("~/GHzT/display.drf" nil)

in my .cdsinit but it has no effect. If I execute this command in the CIW directly after starting virtuoso and after that I open a layout, my display.drf is also not loaded. But if I open the layout before I execute this command, the display.drf loads correctly and the layers appears as I want to.

Can anyone tell me what I am doing wrong?

Thank you!

Sascha

PS: Sorry for my bad english!

    It could be that the library containing the cellview you are opening has a display.drf defined inside of it. To work around the problem, you could open the library in your .cdsinit before running the drLoadDrf command. In our projects, we have a PDK library that contains all of our technology file settings and a default display.drf. This library is named the same in all projects. By doing a ddGetObj("libName") on the library in the .cdsinit, we can force the skill pcell code to get loaded at Cadence startup instead of at the library access time. This is probably why my drLoadDrf works in my .cdsinit.

    I have tried this method you mentioned above, but it also doesn't work. When I open a layout after I execute this command in my .cdsinit, the layers is inconformity as I want. So I want to confirm the command "ddGetObj("libName")" is the whole command which can achieve my goal of loading my own display.drf file?
