Atmel Corporation 

DSR Meeting

Phase 2:

Logic Design

LR Meeting

Phase 3:

Physical Design

DR Meeting

During the feasibility phase, several meetings and reviews can be set up if some technical

details have not yet been defined and agreed.

The results of the feasibility study are gathered in a report provided to the customer and

reviewed during the Feasibility Study Review (FSR). The FSR can be either a conference call or

a meeting. From the FSR onwards, a firm quotation can be issued.

As soon as the NRE order is placed, a Design Start Review (DSR) is organized.

The DSR is a kick off meeting of the ASIC development between the customer and Atmel (under

the responsibility of the Marketing) and involving the Technical Center, the Product Engineering,

Sales and any other necessary resources.

This phase consists of building the project database at the logic level, using a selected set of

CAD tools. It consists of creating a first net-list (interconnection of Atmel ASIC cells) describing

the behaviour and the structure of the circuit.

Once the logic design is completed and checked at the logic level, a formal meeting is set up

involving the customer and Atmel, for the official freezing of the data and the start of the physical

design.

After the customer’s design data has been transferred to the Atmel Technical Centre, the layout

is performed.

Then, post layout simulations are run and back annotations given to the customer. Changes can

be made on the layout until the best trade off is found between Atmel and the customer, pro-

vided it has been approved before.

.

Once the design layout is completed, the entire circuit database is reviewed by the customer

and Atmel in order to validate the physical design.

The main criteria to be checked are:

• Simulation results with post-layout back-annotation timings.

• Layout organization with bonding diagrams and package features.

• Test program in compliance with Atmel tester rules.
