ADIVA is now offering its Design
Analysis tools as an Internet Service via our secure Internet
portal. The ADIVA tools provide the essential verification step between
the CAD Design Workstation and the Printed Circuit Board Manufacturing
and Assembly industry. Our primary
goal
is to save you time and money. We accomplish this by verifying the integrity
of data output from the CAD system – will each circuit card meet the requirements
of not only manufacturing and assembly but also the intent of the original
circuit design? This task is achieved
through several advanced analysis routines, which include . . .
CAD
TO GERBER NETLIST COMPARISON
· Extract netlist from GERBER or ODB++ database
· Extract netlist from CAD database
· Compare netlists GRAPHICALLY
·
Search for netlist differences – GRAPHICALLY display

· ELIMINATE post fab connectivity problems caused by GERBER data
anomalies through Virtual Manufacturing

Design Analysis Service Form
This rule form is designed to show the
selection of checks to be applied and the values intended for each.
Net Comparison is an automatic
process. Analysis will report Shorted
and/or Broken nets along with any missing or extra component pins.

if extra detail is required.
***
The following Performance
Rules can be run on specific nets (such as critical routes) thus reducing
report on unimportant nets. Please
provide separate ASCII file listing net names to check (one net name per
line - wildcards (*) ok). Otherwise report will be
generated for all nets.
