MODULE DESIGN IMPLEMENTATION
Prototype build:
Telford Oldham
Non released BOM Release BOM’s & Spec’s.
Long lead time parts flagged to Procurement
2 iterations All iterations
Prototype shop Prototypes done in Production area
Process:
Library of approved parts
Method of creating new parts
Component Approvals Engineer
Simulation of Modules:
Calculate / Simulate Shoot designs into simulation
Design Aid
Circuit Design:
Calculations
Schematic - Engineer; check; pass to CAD; CAD check.
PSPICE simulation for critical functions.
Prototype testing
Integration of mechanical design for early PCB’s
Rules driven design - (Design for EMC; Design for Test; Design for Manufacture)
TOOLS FOR DESIGN
What do we want to do? Can we justify a full Simulator? What are the options - PCAP; OrCad; View-
Logic ?

COMPARISON OF CADS PACKAGES
POSITIVE NEGATIVE
VUTRAX
Modular Package Ease of use
3D output Cost ?
Nerissa currently uses Engineers familiar with it
Powerful
Reliable
Functionality driven by customer
Vutrax Gerber
Panelisation
PSPICE module
4TH
Shift interface
POWER-LOGIC / PCB
Modular to a lesser extent No 3D (no direct SDRC interface except DxF [2D])
Schematic capture only £800 No panelisation facility - external package
2D output and input Training for Nerissa
OLE connection between schematic & PCB and
also to ViewLogic
Reliable
Market driven
GUI interface
Paul / Sacha use it
Ease of use
Preview of Gerber output
OrCad
Cheap Not so cheerful
Easy to use 2D drawing package not good
CIS - integrated comp. database Comp. Database not controlled, can’t o/p to Sub.
Contractor for approved component information.
PSPICE integrated PCB & Schematic have serious bugs.
IDEAS import Poor schematic capture
Previous versions used by development engineers Poor support
ACTIONS FROM MEETING:
Intranet DPM given to Keith Reynolds on CD
CADStar demo at Telford on 15th
April
Sacha to lend his copy of Power Logic & PCB to Mark Hamer for 2 weeks
Sacha to bring examples of DPM documentation.
Next meeting : TBA
