Design for
Manufacturability Coalition (DFMC)
Introduction
Design for Manufacturability design flows have become
increasingly critical as normal excursions in
semiconductor manufacturing result in significant
variations for yield, power and performance at 45 nm
process nodes and below. Both Process limited yield
(PLY) and Circuit limited yield (CLY). lower
manufacturing profits since these circuits must be
scrapped or sold at a discount because they miss the
power and/or performance targets of a nominal device.
In response to these issues, the
Design for Manufacturability Coalition (DFMC) has
developed a standard interface format that describes a
comprehensive set of
DFM parameters that can verify that a circuit will meet
it’s profit targets. The DFM parameters are defined in
an open-source and extensible standard format called
OpenDFM which provides a common set of DFM parameters to
a wide variety of physical verification and analysis
tools dramatically improving the interface between EDA
vendors and
silicon foundries.
Plans for 2012 include: OpenDFM
2.x to include DRC+ and other enhancements, OPEX 1.0 to
include
open parasitic extraction parameters, and a new
standard, OpenLVS, to cover LVS.
