Explore Impacts of Finite Interconnect Impedance on PDN Characterization

Over the past few decades, many details have been worked out in the power distribution network (PDN) in the frequency and time domains. We have simulation tools that can analyze the physical structure from DC to very high frequencies, including spatial variations of the behavior. We also have frequency- and time-domain test methods to measure the steady-state and transient behavior of the built-up systems.

All of these pieces in our current toolbox have their own assumptions, limitations, and artifacts, and they constantly raise the challenging question that designers need to answer: How to select the design process, simulation, measurement tools, and processes so that we get reasonable answers within a reasonable time frame with a reasonable budget.

Read this award-winning DesignCon 2024 paper titled “Impact of Finite Interconnect Impedance Including Spatial and Domain Comparison of PDN Characterization.” Led by Samtec’s Istvan Novak and written with a team of nine authors from Cadence, Amazon, and Samtec, the paper discusses a series of continually evolving challenges with PDN requirements for cutting-edge designs.

Have you ever thought of a handy utility to specify all necessary transmission line parameters to decide upon the stackup?   

Starting SPB 23.1, a handy feature Transmission Line Calculator, is built into Allegro X Advanced Package Designer (Allegro X APD). This feature will require either an SiP Layout license or can be accessed through SiP Layout Bundle. 

From the Analyze dropdown menu in the 23.1 Allegro X APD toolbar, you can choose Transmission Line Calculator. 

You can use this calculator to help decide constraints and stackup for laminate-based PCB or Packages. You can calculate the correct stackup material and width/spacing to meet any requirements that may be later entered in a constraint. This is truly a calculated number and not a true field solver. 

The different types of calculations that the Transmission Line Calculator can provide are Microstrip, Embedded microstrip, Stripline, CPW (Coplanar), FGCPW (frequency-dependent Coplanar), Asymmetric stripline, Coupled microstrip (Differential Pair), Coupled stripline (Differential Pair), and Dual striplines. 

This feature is important for customers relying on fabricators/spreadsheets to provide this information or need to test a quick spacing/width as per the impedance value. 

Let us know your comments on this new feature in 23.1 Allegro X APD. 

Hi，

There are mang components in BGA ball side of flipchip package.

Are there DFA check space of compont body or pin soldermask to BGA ball or BGA PAD or bga  soldermask in allegro APD?

I only find space of compont to compont in APD DFA. 

By default, a dielectric must separate each pair of conductor layers in the cross-section of a design. In rare cases, this does not represent the real, manufactured substrate.

If your design requires you to have conductor layers that are not separated by a dielectric (such as, for half-etch designs), there is a variable that needs to be set in Allegro X APD. You must set this by enabling the variable icp_allow_adjacent_conductors. This entry, and its location in the User Preferences Editor, are shown in the following image.

The Objects on adjacent conductor layers do not electrically connect together, automatically. A via must be used to establish the inter-layer connections.

When enabling this option, it is recommended to exercise caution because excluding dielectric layers from your cross-section can lead to inaccurate calculations, including the calculations for signal integrity and via heights. It is important that your cross-section accurately reflect the finished product to ensure the most accurate results possible. Any dielectric layers present in the manufactured part need to be in the cross-section for accurate extraction, 3D viewing, and so on.

Let us know your comments on the various designs that would require adjacent conductor layers.

When working on a complex design, it is common to have very many net ratlines. Quantities like 1000 ratlines are possible. It can result in a cluttered view while routing. Therefore, it is useful to make all other ratlines invisible while routing interactively. You would like to make all ratlines visible again when each route action is completed.

You can easily do this by enabling the Auto-blank other rats option during routing. When enabled, all rats other than the primary ones are suppressed during the Add Connect command.

As technology continues to evolve at a rapid pace, the importance of robust and efficient interconnect standards cannot be overstated. Peripheral Component Interconnect Express (PCIe) has been a cornerstone in high-speed data transfer, enabling seamless communication between various hardware components.   

With the advent of PCIe 6.1 ECN, a significant advancement in speed and efficiency, ensuring the accuracy and reliability of its operations is paramount. One critical aspect of this is the verification of shared credit updates. For detailed understanding on Shared Credit, please refer Understanding PCIe 6.0 Shared Flow Control. 

In this blog, we will discuss why this verification is essential and what it entails.  

Introduction 

PCIe 6.1 ECN brings numerous advancements over earlier versions, such as increased bandwidth and faster data transfer speeds.   

A crucial mechanism for efficient data transmission in PCIe 6.0 is the credit-based flow control system. In this system, devices monitor credits, representing the buffer capacity available for incoming data.   

When a device transmits data, it uses credits, which are replenished or adjusted once the data is received and processed. This system ensures that the sender does not overload the receiver.  

Given the critical role of shared credit updates in maintaining the integrity and efficiency of data transfers, verification of these updates is crucial.  Proper management of credit updates is essential to ensure data integrity, as any discrepancies can lead to data loss, corruption, or system crashes.   

Verification also guarantees efficient resource allocation, preventing scenarios where some components are starved of credit while others have an excess, thus avoiding inefficiencies.  Credit inefficiencies pose issues in low power negotiations by preventing devices from entering low power states. Additionally, verification involves checking for proper error handling mechanisms, ensuring that the system can recover gracefully from errors in credit updates and maintain overall stability.   

PCIe 6.1 ECN Flow Control Optimizations Over PCIe 6.0

PCIe 6.1 ECN builds on the FLIT-based architecture introduced in PCIe 6.0, further optimizing flow control mechanisms to handle increased data rates and improved efficiency.  PCIe 6.1 ECN introduced refinements in credit management, making the allocation and advertisement of credits more precise, which helps in reducing bottlenecks and improving data flow efficiency.  Enhancements in flow control protocols ensure better management of buffer spaces and more efficient credit allocation. These enhancements are designed to handle the increased data rates and throughput demands of next-generation applications, ensuring robust and efficient data flow across PCIe devices.  

Below are some major updates: 

1. There have been improvements in error detection and correction mechanisms in PCIe 6.1 ECN to enhance flow control reliability by ensuring that corrupted data packets are detected and handled appropriately without disrupting the flow of valid packets.  
2. The merged credit system, which was a key feature introduced int PCIe 6.0 to simplify and optimize credit management, was further enhanced in PCIe 6.1 ECN to improve performance and efficiency.  
3. PCIe 6.1 ECN introduced better algorithms for allocating and reclaiming merged credits to handle high data rates, introduced more robust error detection and correction mechanism reducing the degradation or system instability. 
4. PCIe 6.1 ECN provided clear guidelines on how to implement the merged credit system correctly, helping developers to implement more reliable systems. For more details, please refer to Specifications section 2.6.1 Flow Control (FC) Rules.

Summary 

In summary, PCIe 6.0 is a complex protocol with many verification challenges. You must understand many new Spec changes and think about the robust verification plan for the new features and backward compatible tests impacted by new features. Cadence’s PCIe 6.0 Verification IP is fully compliant with the latest PCIe Express 6.0 specifications and provides an effective and efficient way to verify the components interfacing with the PCIe 6.0 interface. Cadence VIP for PCIe 6.0 provides exhaustive verification of PCIe-based IP and SoCs, and we are working with early adopter customers to speed up every verification stage.

I exported vplan to .odf file in vManager and after editing it I imported it to vManager. The vplan was expected to be synchronized and updated. However, nothing has changed to it. Does anyone know why?

hello

is there a way to update one dynamic shape instead of updating all dynamic shapes?

i have over 6000 dynamic shapes on my design and it takes over 10 mins to update them all.

i just would like to update only one dynamic shape sometimes to find out if placing vias and lines in a shape has enough space or not.

regards

masa

The default behaviour of Place replicate update is to select every new net item connected to the replicate module. This leads to an abundant number of clines, vias and shapes being selected, most of which I don't want to add to the replicate group. It is very tedious to unselect all these items and more often than not, I miss one or two items and then end up with a via or cline in a completely different place on the board or outside of the board.

Is there a way to change this rather annoying behaviour? I haven't found any way to disable it or to batch deselect everything the tool has decided to add to the replicate group.

The question has been asked before, but it didn't get any answers and the thread is now locked.

I am using OrCAD PCB Designer Standard version 17.4-2019. I want to force update the Package_Height_Max property on the place bound top shape. The footprint library that we've created has that property set in the dra file, but I'd like to override that from capture so I can be certain that the height is correct.

This is coming from a place where we have created a very large footprint library over that past ++ years. Everyone who creates a new footprint is supposed to make sure that we add Package_Height_Max to the footprint, but of course footprints get reused for various parts, not all of which will have the same package height. What I want to do is export a list of package heights from our part database and then import the package heights into Capture and override the package height in the footprint.

I have found a post here  Using Height Property from Orcad Capture which says its not possible, but it also says its from 15 years ago, so maybe things have changed?
