add new package in ads

I am using atf36077.its package mentioned in datasheet is style 77.But i have not found this package in ads2003a.in data sheet dimensions of package provided .How can i create new package in ads2003a using these dimensions in order to create layout.

you can create the artwork in the layout editor.

it is hard to explain all the steps of creating a layout here....

hi ahmad,try to use any amp. that has the same foot print of ur transistor,reply me at pm

abdoeng: unless the sample layout is provided. The dimension of the amp will not be the same. It is still better to draw it yourself at layout window (both ADS and MWO can do so). But it is a very long explaination through words here...
