ASP DAC 2009
- ASP DAC attendance was within reason. The conference
was energetic and technically excellent.
FIRST KEYNOTE: MITSUO SAITO, TOSHIBA
The Start-up activity in EDA is still strong. EDA as a
whole is not consolidating but there is consolidation
going on in some segments of the EDA market.
Taking Toshiba’s design projects as an example, Saito-san
showed how electronic design was evolved from the past,
and predicted that “co-design of dedicated hardware and
software” is the future of design in 2017. In the meantime,
power consumption will continue to be an issue for the
ESL METHODOLOGY PANEL
The fewer number of hardware vendors will also decrease
the hardware variety, but software design cost may lower
as well. In the future, if software design cost keeps
increasing, it may not be able to support many platforms,
and the software design will be free from standardization.
The thing that stood out was ARM’s hold on SoC designs
3RD KEYNOTE: LEON STOK, IBM
Model-based DFM didn’t take off because of the complexity
and the amount of time it consumed.
Prescriptive Design Rules (PDR) tell you what you can
do rather that RDRs that tell you what not to do (prohibitive).
PDRs are a set of design rules that tell you what’s allowed,
and also have a set of prescribed patterns that allow
layout configurations. The results of PDR are predictable
layout constructs with predictable yield and circuit performance.
Emersion Lithography also allowed you to cut down on DFM
tools. At 32nm the main effort is to tune your lithography
to your allowed features.
- 32nm is too small for the old 65nm double via rules.
At 32nm extraction models need rewriting. PDR cuts down
on the number of models that need to be written (but requires
very clear cell boundaries).
