The Exar public website is utilized to communicate product information to its Customers. Inquiries,
contracts or order placement/acceptance and amendments are channeled through the Sales
department utilizing applicable procedures. Results of review, when applicable, are communicated to
Customers for confirmation.
Sales department utilizes the CustomerSupport@Exar.com email box and the RightNow system to
manage requests for product information, Return Material Authorization and Corrective Action
Requests. Customer Corrective Action Requests (CCARs) are handled through the CCAR@Exar.com
email box. The Customer survey system is used to enhance Customer satisfaction and may make
associated department referrals to address Customer complaints. Customer surveys shall be used to
obtain feedback and focus on enhancements to improve Customer satisfaction.
Exar employs a “four-phase” system in order to manage and execute its new product design activities
on schedule and in a cost effective manner. These activities are outlined as follows:
Phase 1 – Product Definition
Phase 2 – Design Phase
Phase 3 – Prototype Phase
Phase 4 – Production Release Phase
Process details are outlined in Sections 7.3.1-7.3.7 as noted below.
Design and development activities necessary to meet the specified requirements are detailed in the
product development specifications. Engineering standard operating procedures and general operating
procedures cover the product authorization, development, verification, qualification and validation and,
finally, release to production. They also identify the resources and responsibilities throughout various
stages of development plan and schedule tracking.
Design inputs including statutory and regulatory requirements are reviewed during the project
authorization phase. Product functional and performance requirements are reviewed to determine if
Exar has the capabilities and access to appropriate technologies compatible with the specified
requirements. Information derived from previous designs may be utilized to improve device
performance in the next generation of the related products. Incomplete, ambiguous or conflicting
requirements are resolved with Marketing and, if appropriate, with the Customer prior to completion of
the design and layout.
The output of the design process takes the form of a mask set, test software and hardware, datasheets,
evaluation boards and the necessary manufacturing instructions. Prior to mask making, simulations and
verification steps have to be performed to verify compliance to the specifications as well as
manufacturability. After mask making, prototypes are built to qualify, characterize and validate product
performance against the requirements.
Depending on the complexity and challenge of certain circuit designs, informal design review meetings
will be held throughout the design to solicit input from peers and improve the odds of success. Formal
final design reviews, involving other functions concerned with the new product development, are held
prior to making the first mask set of a product.
Design verifications establish that the design output meets the design input as well as manufacturability
requirements. This is accomplished by circuit simulations, using process libraries, throughout the
design and additional verification programs prior to release to mask making.
