Ask Me Anything with Zuken

Have a question about Zuken? Post on this thread and Steve Watt, Manager of PCB Engineering at Zuken USA, will answer on December 6th!

How can you tell if your AI-powered CR8000 will be reliable? Especially for high-speed designs? Multichip modules?

I’ve never used Zuken but what would you say the key features are when comparing CR8000 to other design tools?

Does CR-8000 provide options for routing transmission lines with controlled impedance?

I’m using E3. Can you tell me how I could modify the size of the connection points on my schematics?

I’ve noticed that my wire and core designators are currently assigned randomly as W2, W3, W5, W7, W8, W10. I would prefer them to be in a sequence like W1, W2, W3, W4, W5, W6.
Is there an automated function available to achieve this? Also, I’m looking to correct the sequence of core numbers.

Using E3

Is there a way to import an existing footprint into a new one without encountering the issue of copying and pasting where all layers are placed onto the active layer rather than their respective layers? Additionally, is there an option for a direct import function for existing footprints, avoiding the need to copy/paste from an open file?

Do you have built-in features for design collaboration and data exchange?

Hi Mark, AI authored designs will be guided by the same factors that guide non-AI designs in CR-8000 Design Force. Design rules and electrical constraints will provide the guardrails to ensure that AI designs meet their producibility and electrical performance targets.

Hi Pratik, the main points with CR-8000 are a fully integrated system level design approach, in that multiple PCBs can be authored from a single schematic structure, multiple PCBs can be intelligently merged in a single design canvas and that we have an seamless approach to data management. In addition, we have integrated SI/PI capability and also the tool supports 64 bit architecture with multi-core and multi-threading to ensure rapid processing. Lastly we’re investing heavily in AI to ensure that Zuken centered design teams are more productive than ever.

Hi Alex, a user can import an existing footprint and the footprint defined layers will be adhered to in the design. Also since CR-8000 is a library driven design tool, the copy/paste function for a footprint does not exist per se, but a user can add a footprint to the design, place that footprint on the design and then back annotate that information to the schematic to keep the design synchronized.

Hi Hemnandan, yes CR-8000 Design Force has a built in impedance calculator to assist the user in establishing the rules to reach a targeted impedance. Those rules can then be assigned to specific nets or layers and the automatic and interactive routing functions will abide by them. The constraint browser also has the ability to set these rules, adhere to them and provide the user feedback on whether or not the goals have been met. This also applies to differential pair impedance, (Diff.Z) control.

I’m not an E3.series product expert, so I reached out to Laura Mirto, our E3.series Technical Marketing Manager, and here’s what she had to say. Connection points representing T-connections, forced wiring, and open line ends increase in size when the width of any connected connection lines increases. If you have any more questions about this behavior, please don’t hesitate to get in touch with Zuken Global Support.

Hi Ravi, I’m not an E3.series product expert, so I reached out to Laura Mirto, our E3.series Technical Marketing Manager, and here’s what she had to say. E3.series should be assigning device/wire naming in sequence. If the names are out of sequence, for example, if a part was deleted from the project or those devices/wires were copied from another project, then there are several ways to correct this. There is a renaming option with wires when you select multiple wires in the Device tree or right-click on the device folder. In this dialog, you can set the starting and ending wire numbers to rename all selected wires quickly. There are also scripts provided with the software that you can run to rename all wires in your project. These scripts are under Add-ons > Wire Numbering on the Main Menu. Likewise, scripts are available to rename all devices in your project in this same location, but under the Rename device designations section. There are also some mechanisms to perform this for Cables as well. I don’t want to get too lengthy in my response, so the best course of action is to contact Zuken Global Support and they can assist you with any questions you may have on what has been outlined here.

Hi Ishachandra, The question you ask could mean a couple of things, so I’ll do my best here. Yes, we have provisions for both. For design collaboration we have mechanisms in CR-8000 Design Force to allow designers to concurrently work on the same design simultaneously from remote locations and we can also partition a single design into multiple sub-designs that allow for separate access and then a remerge to bring everything back together and make the final tie ins. For data exchange, I’m not sure what aspect you refer to. We do have an Engineering Data Management solution, DS-CR, that’s integrated with our design tools and allows for many important aspects of EDM/WIP data exchange. Please take a look at for more detailed information.

What are the main features of your platform, CR-8000? How does it cater to signal integrity and power integrity analysis?

How does your system handle design data modifications, including customer-requested specification adjustments, changes in component versions, and revisions?

How does Zuken contribute to implementing design rule checks and post-layout analysis?

What are the capabilities of Design Gateway in supporting different design packages?
