s DEVELOPMENT FLOW

Products are developed through the following processes. The illustration below shows the development flow.

(1) Customer Request (Phase 1)

The customer selects an existing macro from the Fujitsu Macro Brochure, for the purpose of producing a system

block in a specific design. If the desired macro does not exist, the customer may request Fujitsu to modify an

existing macro.

(2) Functional Study and Price Approximation (Phase 2)

Based on the customer request, Fujitsu and the customer make an initial study of feasibility. An initial price

estimate is also made.

(3) Development Start (Phase 3)

Based on the results of the primary study, and with the approval of the customer, Fujitsu starts the development

process. Detailed investigation is made including circuit study and simulation of circuit characteristics, a layout

is created, and provisional delivery characteristics (target specifications) are drawn up. The development

schedule, development costs, and price estimate are prepared.

(4) Prototyping and Mass Production

Based on the provisional delivery specifications approved by the customer, the LSI is designed and prototyped.

The standard time for ES prototyping is approximately nine weeks. Fujitsu and the customer jointly evaluate the

ES based on the provisional specifications. If no problems are found, final delivery specifications are approved

and development is completed. The next step, transition to mass production and delivery, requires a standard

interval of approximately three months.
