Description
Atmel's next generation ATL60 Series CMOS ASICs are fabricated using a 0.6µm
drawn gate, oxide isolated, triple-level metal process. Extensive cell libraries are avail-
able and support the major CAD software tools. As with all Atmel ASIC families,
customer involvement and satisfaction is integral to all steps of the design flow. A vari-
ety of Design for Testability techniques are supported by the libraries, and a wide
range of packaging options are available. The ATLS version utilizes a fine pitch stag-
gered row on bond pads to achieve the smallest die size possible for a given pad
count. The ATLS60 is only available in a limited number of PQFP packages.

Design Flow
Atmel provides three methods for implementing an ASIC design while maintaining the
same basic design flow for each method. This flow involves both the customer and
Atmel at all critical review and acceptance steps, as shown on the following page. Data-
base Acceptance occurs when Atmel receives and accepts the complete design
database.
Upon completion of this critical step, Atmel performs physical place-and-route. Func-
tional and timing simulations are performed, based on the physical design, including the
generation of a back annotation report to provide the customer with the most accurate
timing information available. Final Design Review is the last step of the design flow prior
to generation of masks. After this acceptance step is completed, masks are generated
and released, and prototype parts in ceramic packages are delivered.

Pin Definition
Requirements
Within the Physical Design step (i.e., layout), certain restrictions apply during pin defini-
tion. The corner pins on each die are reserved and programmable for power and ground
only. All other buffer pins are fully programmable as input, output, bidirectional, clock-
into-array, power, or ground.
Design Options
Logic Synthesis
Atmel can accept Register Transfer Level (RTL) designs for VHDL (MIL-STD-454, IEEE
STD 1076) or Verilog-HDL format. Atmel fully supports Synopsys for VHDL simulation
as well as synthesis. VHDL or Verilog-HDL is Atmel's preferred method of performing an
ASIC design.
ASIC Design Translation
Atmel has successfully translated dozens of existing designs from most major ASIC
vendors into our ASICs. These designs have been optimized for speed and gate count
and modified to add logic or memory, or replicated for a pin-for-pin compatible, drop-in
replacement.
FPGA and PLD
Conversions
Atmel has successfully translated existing FPGA/PLD designs from most major vendors
into our ASICs. There are four primary reasons to convert from an FPGA/PLD to an
ASIC. Conversion of high-volume devices (over 10,000 units) for a single or combined
design is cost effective. Performance can often be optimized for speed or power con-
sumption. Several FPGA/PLDs can be combined onto a single chip to minimize cost
while reducing on-board space requirements. Finally, in situations where an FPGA/PLD
was used for fast cycle time prototyping, an ASIC may provide a lower cost answer for
long-term volume production.
