In state of the art integrated circuit industry for transistors gate length of 45nm and beyond, the sharp distinction between
design and fabrication phases is becoming inadequate for fast product development. Lithographical information along
with design rules has to be passed from foundries to designers, as these effects have to be taken into consideration during
the design stage to insure a Lithographically Friendly Design, which in turn demands new communication channels
between designers and foundries to provide the needed litho information. In the case of fabless design houses this
requirement is faced with some problems like incompatible EDA platforms at both ends, and confidential information
that can not be revealed by the foundry back to the design house.
In this paper we propose a framework in which we will try to demonstrate a systematic approach to match any
lithographical OPC solution from different EDA vendors into CalibreTM. The goal is to export how the design will look
on wafer from the foundry to the designers without saying how, or requiring installation of same EDA tools.
In the developed framework, we will demonstrate the flow used to match all steps used in developing OPC starting from
the lithography modeling and going through the OPC recipe. This is done by the use of automated scripts that
characterizes the existing OPC foundry solution, and identifies compatible counter parts in the CalibreTM domain to
generate an encrypted package that can be used at the designers' side.
Finally the framework will be verified using a developed test case.
