4. Design Flow
• In UST ECE department, we have a professional team with consultancy experience for
the IP design. They follows the industrial process to enhance the quality of the UST IP
Macro.
• Macro Definition Phase
– Once we have received the request. We will create a Macro Development Planning to make
sure the IP to fit your product development schedule. Besides, we will then define the
specification and evaluation for Mass Production with yours. After that, a detail design policy
will be clear. It is very important to define it out before any design phase, since we will have a
feasibility study of the development and prevent any risks happen. (For Risk preventing, you
can refer to our Risk Management methodology. )
• Pre-Design Phase
– After defining the specification and identified the risks, we will move on the circuit design
phase. With the research experience and the modeling techniques, it can very fast to create the
preliminary circuit set (if it is a new macro request) or to prepare the first database (if it is a
technology migration/ Fab Change request).
• Layout Phase
– With certain specification has been defined and circuit has been implemented, it will go on to
the Layout development. As we have a very strong analog research team in UST, it can also
provide an cost-effective and good noise immunity layout.
• Post Design Phase
– After the layout, we will have post-design phase to ensure the design parameters having the
required margin for the mass production.
• Library Release
– Once the above processes have been completed, the library can be released.

5. Design Service
• There are THREE development scenario
have been considered in IP Development.
a)Migration on Technology
• Customer would like to use current
design, however, they would like to plot it into new
technology (i.e. move IPs from 0.5um to 65nm)
b)Migration between Fabrication House
• Customer would like to use specific fabrication
house, however, IP being developed is not using this
technology
c) New IP Macro
• Customer would like to develop a new macro with
new specification requirement

6. Design Services
• There are THREE development scenario
have been considered on IP Service.
1. Migration on Technology
2. Migration between Fabrication House
3. Development of New IP

7. Migration on Technology
• User can select the macro from
existing IP Catalog and defined their
technology requirement for the new
plotting. (i.e. considering the plotting
of existing IP from 0.5um tech to
65nm tech). Once the requirement
has been confirmed, processes
plotting on technology, circuit
architecture and as small as the
component (such as transistor unit)
will be considered in details to
prevent the failure. It will finally
draft out a IP specification and a
design policy before starting the IP
design. As the quality of the design is
our main concern, the design is
developed under an in-house control
with risk management.

8. Migration between Fabrication
House
• It is considering to product the
required IP Macro from one
fabrication house to another. As
it involves the different
technology requirement in
different fabrication house, it
will need to think about the
different process parameters, the
component availability and the
transistor requirements to define
the risk of this technology
plotting. After a deep
understanding, it is necessary to
reconsider and finalize the
specification as well as drafting
out a design policy to control the
whole IP design without any
failure.

• On developing a new IP, it is necessary
to have a feasibility study with
preliminary specification based upon
your product outline. As it will have a
deliberated study on the
requirement, it is easy to circle out
those design difficulties and
contemplate the solution for those
risks. Thus, the finalized specification
is more practical for your product. In
addition with a good design policy to
control the development, your design
goal can be easily achieved.
Although, it will increase your lead
time on product
development, however, when you
consider your aggregated plan, it may
be shorten, since it not only prevents
the macro from later mask changes but
also saves your time and the cost in
your design.
• If you have any new idea and with like
to implement, please feel free to contact
us to increase your product revenue.

10. Concurrent Engineering
• We also can support concurrent development for time-to-
market requirement. It can help you to maintain a short
product design phase and at the same time reduce the lead-
time of your development

11. FMEA
• FMEA is called Failure Mode Effects Analysis.
• It is a step-by-step approach for identifying all
possible failures in a design. You can consider
“Failure modes” which means the ways in which
something might fail and failures are any errors or
defects which can be potential or actual.
• On the other hands, Effects Analysis is to study the
consequences of those failures which can be
prioritized according to how serious their
consequence are, how frequently they occur and
how easily the can be detected.
• With aboves, we can take actions to eliminate or
reduce failures on the design.

12. FMEA (2)
• In our quality
control, we will
applied it with
DRBFM as a basic
element to enhance
our design IP quality.
• In other ways, you
also can consider
FEMA process being
very simple as it can:
– Save the lead time
– Reduce the number
of changes before
your product launch
– Increase your
customer trust

13. DRBFM
• DRBFM is a proactive problem prevention method.
This helps to find problems through a forum of Good
Discussion with a cross-function team. It can be
considered as designers discuss among the same
team, or discussion in between different design
teams.
• Objectives:
– It helps to identify the baseline design and to focus the
efforts on changes.
– It let IP designer in better understanding the failure
modes and corners (risk) associated with the design and
the manufacturing.
– It helps to prioritize the change by focusing on those
highest risk issues.
