Zuken PWS to Cadence Allegro
Overview
Router Solutions' CAMCAD PCB Translator can prepare
data and translate a wide variety of ECAD formats to other
ECAD formats. More than just a black box translator, the Windows-based
application allows for sophisticated analysis of the data
prior to translation. If any adjustments or edits are required,
the thorough tool set allows users to make modifications.
This three step process, Import, Investigate/Edit, Export,
allows users the most flexibility for their ECAD translation.
CAMCAD PCB Translator reads in the Zuken PWS files
using the .bsf file for it's guide for proper input.
Layermap
In general ECAD layers can be divided into two major catagories,
electrical and non-electrical. Both types can be mapped in
our system to layers expected by the target system. Usually
translation of electrical layers is critical and needs to
be 100% accurate (or nearly so), while more flexibility is
allowed with non-electrical layers. Sometimes non-electrical
layers need to be combined to move the data successfully into
the target system. CAMCAD offers users full visibility
of layer mapping.
In
general if the Zuken-Redac 3000/5000 layer names are standard,
the electrical layers will be automatically mapped to the
proper layers in Allegro. There will always be layer
names we do not automatically handle, and these will have to
be mapped to layers in Allegro.
Just highlight the layer and hit
"Edit", then select the layer in Allegro you want
this highlighted layer to go to. Once all your editing is
complete (you might want to save your layer file it at this
time) just hit "Proceed" then your on your way to
making your Allegro ascii files.
Translation
Process
Import
It is very easy to load your ready to be translated file
into CAMCAD PCB Translator, just go to File
| Import then select the Zuken PWS (CR3000/CR5000)
Layout Read.

Process
Once you have your file loaded into CAMCAD PCB Translator,
you may want to take a good look at what you are trying translate.
See if everything is there like traces, components, component
outlines, vias, board outline and good idea to check a couple
of pad stacks to see if they have the proper layers. Another
thing you might want to do is Purge the unused Geometries.
In addition to that only translate the active layers and you
might to consider removing any or all the grachics you really
do not need.
Export
Now your ready to export and that's as easy as the Import
was. Just go to File | Export
now select the CADENCE Allegro PCB (Script) Write. Now you
are on the way of making a new database for Cadence Allegro.

The Allegro.chk file, this file sets basic rules for the
naming conventions in the Cadence Allegro files. The Allegro.chk
file is rather involved and should not be modified unless
the user possesses a through understanding of the cause and
effect of each line in the file. This file is well documented
with the file itself, but a general overview of the file is
provided in this document to aid in understanding why it exist
and how it works.
The need for the Allegro.chk file arises because of limitations
on allowed characters and the number of characters for different
key fields within the Cadence Allegro file format. Since these
limitation often times change and users may want to implement
varying methods to adapt for the limitations, the concept
of the .chk file was introduced. The Allegro.chk file is separated
into six basic sections.

Log File
There are 2 log files normally generated, 1 is on the import
and the other is on the export. These log files will report
findings which CAMCAD PCB Translator, when we export
we may find items which the new CAD System may have a problem
with. You can find further discriptions of these log files
at the folling links.

Limitations
AutoArc (radius Chamfering) is not supported in the Zuken
Reader.
Reference Designators and other component attribute
placement is not graphically supported in CAMCAD.
At the present time, we have not found any limitations in
the translation.
FAQs
There are none at the present time.
