Design and layout support for CLA70000 arrays is
available from various centers worldwide each of which is
connected to our Headquarters via high speed data links. A
design center engineer is assigned to each customer’s circuit,
to ensure good communication , and a smooth and efficient
design flow. It should be noted that sign-off simulation against
the GPS 'golden' simulator is also supported at our local
design centers.
Held after Layout and Post Layout Simulation
Verification of satisfactory design performance
after insertion of actual track loads. Final check
of all device specifications before prototype
manufacture.
Held after Prototype Delivery
GPS offers a variety of formal design routes as illustrated
in the table below. Differing interface methods allow for
varyinglevelsofinvolvement inamannerwhichcomplements
individual customer design styles, whilst maintaining our
responsibility to ensure first time working devices.
Confirm that devices meet all specifications
and are suitable for full scale production.
DESIGN TOOLS
As part of the design process GPS operates a thorough
design audit procedure to verify compliance with customer
specification and to ensure manufacturability. The procedure
includes four separate review meetings, with the customer,
held at key stages of the design.
The focus of the GEC Plessey design tool methodology is
that of maintaining an open CAD system with all interfaces
standardized via EDIF 2.0 . This enables us to provide full
support for a variety of 3rd party ASIC design tools and
facilitates rapid updating of associated libraries. It also
provides an interface to the GEC Plessey (PDS2) design
system, which offers a total design environment including
behavioral and functional level modelling.
