Re: VME connector models


If you are still looking for P0/1/2 connector models. Contact Harting 
for their appliction which can generate the appropriate models. It 
actually allows you to generate the model based on your pin out 
configuration and I remember generating a MLM model. You will have to 
sign some NDA to get it though.

Regards,

Hi all,
I was searching for SLM models for the VME P0, P1, P2 connectors but 
could  not locate any from the manufacturers(Harting) site. Where can i 
locate these models? Also do the model parameters  vary for different 
manufacturers?

Regards

Re: A doubt in PADS 2005

Hi Nikita,

You are right. To reduce the Crosstalk, we should route the traces orthogonally on adjacent layers. By
doing this we are trying to avoid traces running parallel to each other on adjacent layers

In PADLayout, to set the direction of routing, go to Setup > Layers and set the direction of Routing
(Horizontal or Vertical). If you have any question about PADS, you can post it on PADS-Talk listserver. http://www.mentor.com/products/pcb/pads/listservers.cfm

I hope this will help you.

Thanks,

Darshan Mehta

Hi Gurus,

I have come up with one more doubt.I am currently working in PADS2005.
While applying the dualstrip line concept,the adjacent layers are 
traced orthogonally to reduce crosstalk( am I right?).

Is there any option available in PADS2005 that helps me to check, if 
the layers are traced orthogonally.Please guide me in this issue

Thanks in advance,

Hi All,
I'm working on a Hyperlynx simulation of a VME64x bus, does anyone know
of a source for finding the typical RLC values of the P0/1/2 connectors?
I'm having a tough time getting anything from the connector
manufacturer.

Thanks. (New to the list and the field in general)

Mixed Signal Design Tools Workshop

Dear All,

Georgia Tech is organizing a Mixed Signal Design Tools Workshop on September
16, 2005. For those of you who would be interested in attending, details are
below:

MIXED SIGNAL DESIGN TOOLS IN ADVANCED PACKAGING
An Industry-Academia Consortium Workshop
Friday, September 16, 2005

Georgia Institute of Technology, Manufacturing Research Center (MaRC)
Building, Atlanta, GA  U.S.A.
Map and Directions: http://www.prc.gatech.edu/welcome/directions.htm

Organizers: Profs. Madhavan Swaminathan, Prof. Rao Tummala & Dr. Ege Engin
(Georgia Institute of Technology)

ONLINE REGISTRATION, AGENDA, ACCOMMODATIONS & INFO:
http://www.prc.gatech.edu/events/2005/digital/index.htm
There is no charge for this event. Participants are invited to attend the
PRC Open House on Sept. 19, 2005.

ABSTRACT
A major bottleneck in the development of next generation packaging
technologies is the design tools. Due to the integration of heterogeneous
functions in a package, mixed signal design tools are necessary that are
part of a design flow. The Packaging Research Center (PRC) at Georgia
Institute of Technology has been one of the pioneers in this area,
introducing tools that address the System-on-Package (SOP) technologies.
Design of such highly integrated mixed-signal systems require new tools
