Product Briefing Outline: Blaze DFM, has announced the
Release 1.1 update to ‘Blaze MO' optimization software, the company's
"Electrical DFM" solution. In electrical DFM, "design requirements"
explicitly refers to timing and power (electrical) requirements, not
just geometric information. Bringing design requirements forward into
manufacturing means using the actual timing and power constraints
supplied by the design team to drive what happens in manufacturing.
Typically, this is done by interfacing with the resolution enhancement
technology (RET) process in manufacturing.
Problem: Electrical DFM solutions eclipse the
"shape-centric" DFM tools from other vendors, according to the company
by providing significant gains in parametric yield, reduced power, and
improved performance for sub-100nm process technologies. Unlike earlier
DFM approaches, which are geometric in nature, electrical DFM uses
design intent information (such as timing constraints) to drive a
manufacturing-aware optimization of the design.
Solution:
Blaze MO performs a comprehensive power and timing optimization of a
finished design just prior to the handoff to manufacturing. No changes
to any of the design layers are made during this optimization. Instead,
Blaze MO outputs an annotation layer in the handoff GDSII database that
gives detailed guidance to the OPC flow used in manufacturing. Blaze MO
annotations in the design are used in manufacturing to guide the OPC
process to a solution that is optimized to meet power and timing
constraints. In contrast to the design-oblivious OPC flow that has been
used in the past, with Blaze MO every physical feature is fabricated in
the way that best supports the design objectives.
From internal
benchmarks performed on customer designs, the company claims that
Release 1.1 is up to five times (5X) faster than the previous version.
Blaze MO release 1.1 includes advances to every major function of the
software. It offers patent-pending auto-correlation to existing golden
timing and signal integrity signoff tools, which substantially improves
the ease of incorporating the software into the customer design
environment. The strengthened signal integrity analyses further improve
leakage optimization quality of results by reducing the need for
guardbanding in the design team's optimization methodology. The
analysis engines have been enhanced to account for leakage variation
caused by both systematic and random sources. The optimization engine
was enhanced to support process-window awareness when choosing among
available variants. Lastly, the annotation flow was extended to support
manufacturability awareness in the generation of OPC directives.
Applications: IC designs at the 90nm node and below.
Platform:
Blaze MO is built on the Open Access database. It integrates easily
into existing design flows from Cadence, Synopsys and Magma using
industry standard file formats, including SDC, Liberty, Verilog,
LEF/DEF, DSPF/SPEF, and GDSII. Blaze MO annotated GDSII output can be
used to drive any commercial OPC tool. Blaze MO Release 1.1 is
available on all supported hardware platforms as a free upgrade for
customers under current maintenance agreements.
Availability: July 2006 onwards.
