PADS currently support Windows XP and Windows Vista. For a complete overview of system requirements please go to: http://www.mentor.com/products/pcb-system-design/design-flows/pads/system-requirements
We have performed some limited testing on this platform without initial problems. However - PADS 9.0 is not fully qualified on this platfrom. We are investigating supporting this platform for future releases.
I was asked by Steve Hodges of Microsoft Research (A PADS Customer since 2004) whether a PADS update was available that supported Windows 7. I provided Steve with the answer that you had given to the same question. His response was as follows:
Thanks Paul. I guess you don’t have a lot of influence on Mentor, but it would be so much better if they support Win 7 reasonably quickly after it’s released. The betas have been very stable for some time, so they should have had plenty of time to be working on this – like other CAD vendors are. It was painful last time – Vista support took forever.
What is the current schedule for the PADS release that will officially support Windows 7?
Agreed - the reports on Window's 7 beta look pretty good!
We (PADS) want to support Window's 7 pretty quickly - there will not be the lag you saw with Vista.
Our current plan is to support this OS in Q1 of 2010.
PADS 9.0 supports conversion to previous PADS versions using the ASCII out function.
PADS 9.0 introduces several new products to the flow, such as DxDesigner. In order to support the new tools and technologies the format of PADS libraries is differs from previous versions.
PADS 9.0 includes a library converter to translate previous PADS libraries to the new PADS 9.0 library format. Once the library is translated it can be used in PADS 9.0 and in subsequent releases.
Yes - you can install both PADS2007 and PADS 9.0 on the same computer.
PADS 9.0 is shipped with DxDesigner 2007.5. You should be able to read a netlist from DxD 2005.x. However, PADS 9.0 does use a newer ASCII format. You will not be able to perform functions that directly link PADS 9.0 and DxDesigner unless you are using the DxDesigner 2007.5 release. You should strongly consider upgrading your DxD version to 2007.5 to enjoy its many improvements and benefits as well as the tighter integrations with PADS 9.0. Typically there is no cost to the upgrade from previous DxDesigner versions if you have an active support contract.
PADS 9.0 may be installed on the same system at PADS 2007. You can use the configurator to go between versions.
DxDesigner databases in PADS 9.0 are not backward compatible. Once a schematic with a previous PADS release is opened in DxDesigner 2007.5 it cannot be read back in PADS 2007 again.
With PADS 9.0, the translators are part of the tool, ensuring quick migration of your schematics, PCBs, and libraries to the new flow. PADS translators are extensively tested to allow a safe transition. In most cases you just open the old design format within PADS, making the transition process seamless.
Can you please explain what does it mean by "maybe translated" r u guys are not sure, please let me guide how could i translte my protel libraries into pads 9.0
Translators from the listed tools to DxDesigner are available. The translator is shipped with the PADS 9.0 software. There are also translators for the pcb databases into PADS Layout.
You can see a list of PADS schematic and layout translators on:
You might be interested in watching this demo on PADS translation--"Translate Altium Designer, Protel, P-CAD, OrCAD, and CADSTAR designs into PADS"
To enable upward migration to Expedition Enterprise, PADS 9.0 does contain a converter from PADS to Expedition. However - because Expedition Enterprise contains advanced technologies not available in PADS, you cannot migrate from Expedition Enterprise to PADS.
PADS and Expedition Enterprise have different database structures. Reuse blocks in an Expedition Enterprise central library cannot be imported or used in PADS.
PADS Logic has the ability to import a SPICE netlist. If you need more integrated analog simulation, you should look at DxDesigner and HyperLynx Analog.
I think there is a mistake. PADS Logic can export Spice Netlist when all the definitions are correct but can not import a spice netlist
DxDesigner for PADS 9.0 has a number of new enhancements besides better integration and enhanced ease of use. For more details watch the in-depth webinar titled "What's New in PADS 9.0" and look at the on-demand 30 minute demo. Both may be viewed at your convenience at http://www.mentor.com/pads/
PADS 9.0 includes a major enhancement called "Update from Library". For more details watch the detailed on-demand webinar titled "What's New in PADS 9.0". You can view this video at http://www.mentor.com/pads/
PADS 9.0 can be integrated with both PADS Logic or DxDesigner. For users who desire a higher level of integration with engineering processes such as FPGA to Board optimization (I/O Designer) or the advanced simulation capabilities of HyperLynx, then we have released PADS 9.0 with a tight integration with DxDesigner 2007.5.
The newly introduced DxD040, which is specifically defined for the PADS flow provides access to both, PADS Logic and DxDesigner. All other DxDesigner packages do not include PADS Logic.
As part of the PADS 9.0 release there is a DxDesigner Evaluation Guide included with designs and library parts included.
I/O Designer is the tool I am referring to. It can automatically create fractured symbols, as well as help optimize the FPGA pin assignments. More information can be found on mentor.com.
DxVariant Manager has been rewritten, and is now called Variant Manager. It has the same functionality, but is easy to use and more integrated in the DxDesigner environment. Any variants defined in DxD can still be brought forward to PADS Layout and Assembly Variants.
There are some users who work only in Layout, while others will take advantage of both. To go to one executable is a major engineering effort, almost a total re-write of the code. In PADS 9.0, we improved the integration of the two environments to be a “push-button”. In a release next year, you will see something even better! Stay tuned!
It is not possible to generate ODB++ files from PADS at this time but we are investigating offering this functionality in a future release.
Not yet. For this, and several of the product enhancement requests that were submitted during the webinar, check out Mentor Ideas. This is a site that allows you to submit product enhancements requests, or “ideas”. Better yet, you get to view other users ideas, and “promote” or “demote” them. What this does is allow the users to help prioritize all the ideas submitted by our user base. To give you quick, easy access to the site, for PADS 9.0 in the Help menu, you will see a new entry “Submit an Enhancement” which will take you directly to Mentor Ideas.
PADS was enhanced in PADS2007 with RF capabilities that included true chamfered corners, channel wave guides, via fill commands, and enhanced DXF input for RF components.
Our developers and engineers are constantly improving the routing algorithms. There were specific enhancements with regards to routing short differential pairs. We also added the ability to automatically “tune” differential pairs to insure that each trace of the differential pair is exactly the same length.
With PADS 9.0 we now allow padstacks with chamfered and rounded corners. You still have the ability to create custom pads of any unique geometry in PADS.
PADS has the Advanced Packaging Toolkit for the designs with bare die. There is too much functionality to go into this now. There is a data sheet you can download at mentor.com/pads, or contact you sales person for more information.
Test points can be a surface mount via.
I want to be able to assign a number to the test point. How can I do this?
Several defects associated with alpha numeric pins been corrected. PADS 9.0 recently posted a patch release called Update 1 that corrects an issue with alpha numeric pins. Please see http://supportnet.mentor.com for further details.
Yes - PADS 9.0 has this functionality.
I believe you are referring to the I/O Designer functionality. This tool insures that any swapping of pins of an FPGA, whether done on the schematic or in PCB layout, get passed correctly, and a new pin file is generated for use by the FPGA tool.
The DXF import commands were enhanced in a past released specifically to be able to more easily create RF components which were initially designed in a mechanical or RF analysis tool.
PADS 9.0 has a 3D Viewer included (with an upgradeable version) as well as integration to visECAD.
There were many questions regarding the new PADS 3D Viewer. I’ll try to sum them all up here. This is new viewer which allows you to view your PADS design in true 3D. From the View menu, launch 3D Viewer. By default, it will use the geometry.height attribute for the components height. You can then pan, zoom, and rotate the entire PCB assembly. If you have the upgradeable option, you can read in the actual 3D model of the component. You would need to get this 3D model from your mechanical tool, the vendor, on the web, or another source. These models can be WRL or STL formats. With this module, you can also read in mechanical auxiliary files (such as brackets, enclosures, cases, etc.). This is functionality within PADS. There is no export from the 3D Viewer. If you wish to export the design to other tools such as ProEngineer, Soliworks, AutoCAD, etc, you still need to rely on our DXF and IDF Links. At this time, the 3D Viewer does not import or export STEP or IGES. The 3D models are stored in there own folder, not in the Decal library. You will be getting these models from your mechanical group or another source, so storing them external to the Decal library is a better process. In the next month we will hold a webinar that will offer more detail on the 3D Viewer.
Expedition PCB is a part of the Mentor Expedition Enterprise flow; as the name implies, this flow is targeted at company design teams who need more comprehensive process automation & concurrent design, virtual prototyping, cross-domain collaboration, component & design data management with deeper PLM/PDM integration, advanced technology support for today’s and the future’s most complex designs.
The PADS products are really all about personal productivity, reliability and support and now, with the introduction of the PADS suites we are providing the most comprehensive and cost effective range of technology ever (schematic entry, component & variant management, analog design, signal & thermal integrity analysis, PCB layout, & 3D visualization). And with growing technology requirements, such as GHz design and analysis you can easily expand into the bigger versions of the products included in the suites, which allows scalability within the products you are already familiar with and expandability into more comprehensive solutions for design and manufacturing On top of this, PADS is the most widely used PCB design system for personal PCB design which means there is a tremendous amount of industry support through design service companies, contractors, consultants, designers and design/parts data.
Have a look here, I think it says a lot:-
Any Possibility of getting a "Donut" shape for Keepouts (ie inside and outside diameters)?. In the past, I would need to create a "path" with small steps to create unique shapes
