You need to alias the device to something unique, such as the part number so you get a different device file for each different part number. Mike Chombeau ...
Hi Mike, I run DxD to Allegro netlists, and have not seen this problem...so I'm not sure what you mean. Two different parts can't (shouldn't) have the same ...
Hi John, Yep, Ok, so we realized early on that the Mentor Expedition Cell previewer was useless out of the box for a few key reasons - Just for now, forget the...
I agree that performance is really bad for large libraries. We have about 15,000 cells in 18 partitions. I do notice something different from what you...
Yep, it's the same old viewer, just faster. All of our symbols and cell libraries live on the network. The windows users gain access to the libraries via...
Yes, we are using the CDB method. We are converting over from the Boardstation flow to Dxdesigner/DxDatabook/CES/Expedition flow. We are getting pretty good...
My protel conversion to Dx has a filled pollygon for a QFP part(or symbol). 1. The color fill in the polygon writes over the text inside the part. Is there a...
I couldn't make it this year due to a vacation the week before (The cruise was nice) I see the DxDesigner presentations were highly rated this year. I know I...
At U2U a few years ago we asked to reexamine the order of the how items are displayed. I don't think anything became of it. I always found it was too easy to...
Gary, We missed you. There was no road map given for DxDesigner this year as Mentor is making some major changes to the underlying database and wasn't ready...
I agree with Tony. U2U is supposed to be your vacation. The database change has me very concerned. Mike Chombeau Validation Hardware Oregon 503-264-1808 ...
I have a flat schematic design and the component information needed to generate a bill of materials is specified as attributes on the instantiated components...
I have a symbol that is physically one pin on the mating side, but is 4 pins on the PCB footprint side. I would like to have my symbol show only one pin (since...
I have a symbol that is physically one pin on the mating side, but is 4 pins on the PCB footprint side. I would like to have my symbol show only one pin (since...
In a schematic symbol, you typically have a separate electrical pin for each physical pin on the board. The fact that the pins are electrically connected...
Hi, I think this may be a deficiency of the PCB tool in some cases. For example, I have a part that has a central thermal pad, and the PCB requirements are...
It would help to know what tools you are using for schematic capture and layout. ... is 4 pins on the PCB footprint side. I would like to have my symbol show...
Whenever I starts DxDesigner I got the error message which says "ActiveX component can't create object:scripting file system object" if I press OK then nuthing...
Sounds like a problem in your PATH variable. Try moving the mentor stuff to the front of the PATH. Mike Chombeau Validation Hardware Oregon 503-264-1808 ...
Hi Mike, There is no problem with the variable, I have consult with mentor people and set the variables as they suggested. So some other problem is there.Also...
Keith, I am using the same tools as you. I have found the best cure for this is to use the same number of pins on the schematic as in the layout. Ralph Longton...
You can use the Signal attribute on the symbol. It should be placed at the symbol level and then can be changed at the schematic level. Example would be...
Keith, You could add the SIGNAL attribute to your DxDesigner logic symbol. You can assign a generic net name to those pins and edit the value in the schematic...
Sure that works for a particular instance.But to me this can be a liability. If you use the symbol in another schematic you will need to assign a new value to...
I agree if you do not pay attention you can have a big problem when the board comes back wrong. The alternative is to have all the pins on the symbol. Regards,...
You are correct. You need to be diligent when using this attribute, but it is a good way to assign nets to unseen pins. You can use as many instances of the...
One way around the issue is to make the attribute value visible on the symbol ... -- *Jason Stubbs* /*Efficient Channel Coding*/ 4830 East 49th Street Cuyahoga...
