how inherit parameters (w, l and mi) of schematic to layout pcell?

archive

Hi,


Somebody help me in performing the following.

I have created layout PCELLS graphically for couple of transistorsand save them in a lib .I also copied the symbol view ( from technology lib) of the respective transistors in the same lib (as of PCELLS) and copied the CDF data to the lib ( CIW--> tools-->CDF-->copy).

I now create a new schematic in a new lib instantiating symbols from PCELL lib.
I also create a layout view in new lib. I copy transistor symbol view from new schematic and paste it onto layout. Now i change the view type of the transistor symbol to layout.

here i want to know how the properties (w, l etc) of the schematic symbol can be inherited to parameters of the pcell (layout)  so that depending on the w/l etc defined in the schematic the pcell takes these values and the PCELL changes the size.

i hope i am not confusing.

Regards
Kiran

  • I tied that without VXL and it works copying from the schematic view into a layout view then changing the view from symbol to layout. It also works the other way from the layout to the schematic. Maybe you need to correct the CDFs since you copied them.
