General HyperLynx-related questions

I experience troubles with installing HyperLynx and reaching the licence, is there a short manual for that?
Please follow the requirements of the HyperLynx License and Software Installation Guide during the installation and licensing.
How to run a first signal integrity simulation at HyperLynx? Is there a short guide for that?
We have prepared a short video for you. It is explaining how to run SI analysis in short.
We are working at frequencies of 10 GHz and higher, up to 24 GHz. What HyperLynx bundle is suitable for this application?
The most suitable software that supports multi-GHz simulations, has DDR wizards and SERDES analysis included, is the HyperLynx GHz bundle. Please contact us to get a personalized quotation from Sintecs.
We would want the DDRx Wizard, is it a part of the HyperLynx SI ALT bundle?
HyperLynx SI ALT bundle allows running core simulations over DDR circuits. However, DDRx Wizard is not a part of the HyperLynx SI ALT bundle, so performing DDR timing analysis, for example, is not possible with this package. Alternatively, Sintecs can suggest the bundle called “HyperLynx SI DDR”. DDR simulation is enabled in this software package. Please contact us to get a quote.
Is it possible to somehow calculate resistance on a not-homogenous polygon (for now just for DC voltage) based on copper thickness, is the software HyperLynx possible to calculate it?
Siemens EDA (ex-Mentor Graphocs) has some elaborate bundles capable of calculating that. Specifically, the HyperLynx PI DC Drop PE bundle is suitable. Sintecs is an authorized reseller of the whole HyperLynx product line.
How to use sweep analysis feature of HyperLynx?
Is it better to go with S-parameter simulations maybe instead of IBIS-based simulations?
S-parameter simulations are commonly used for the evaluation of high-speed circuits or RF signals. These models describe transmission lines without taking into account the driver and receiver. This means that the signal can be judged on the losses in the line, as well as on impedance inhomogeneities. The S-parameters do not replace IBIS models but represent another aspect of SI verification. The advantage of S-parameters is the ability to estimate the transmission line without any third-party models. IBIS models describe the driver and receiver, as well as parasitic properties inside.
I need a solution to create component IBIS models using the I/O buffers data and the package pin information and apparently, this tool is doing in part what I need. What I don’t see how it is handled in this tool and what other solutions I examined don’t do, is the use of [Model selector] IBIS feature. Do you have a user guide for the tool or can you explain please how [Model selector] can be used in this tool to associate more than one buffer I/O model to a single pin? Is IBIS Developmens Studio designed to use [Model selector] IBIS key word? How can I use it?
IBISDS tool supports Model selector feature. In an IBIS file it should look like:
1. Original buffers must be listed under the Model Selector section

2. The name of the model selector must be used for the model name in the pin section instead of buffer names
Errors are when using illigal symbols on buffer names, such as “.” and “,”. We recommend to replace all the special characters by underscore symbol “_”.
Where can I find IBIS models for proper SI analysis
IBIS models are available not for every single IC. But some of the models can be judged as similar, trusted models, as long as they correspond to signals and frequencies in properties (see IBIS DS for these matters). Though using such replacements can slightly decrease the accuracy of the simulations.
What version of HyperLynx allows working with the Touchstone data format?
HyperLynx SI GHz has a Touchstone file viewer included in the program package, as well as a full HyperLynx SI PI license.
With which bundle it is possible to run timing simulations over DDR5 circuitry?
DDR5 analysis capability (in other words a full DDR Wizard feature) is included in bundles HyperLynx DDRx, HyperLynx SI GHz and the full license HyperLynx SI PI.
How to use HyperLynx Connector extension to set up the environment of HyperLynx?
Is it possible to design antennas using HyperLynx software?
Designing antennas is related to RF technologies. It can be performed using the solution of Siemens called HyperLynx 3D EM which can generate radiation patterns but it is not specialized in antenna design.
I am attempting to simulate a dc power drop of both a positive rail and a negative rail. I have setup a 2.3V VRM source to be connected across R21, WRT R24 as shown below. I then want to simulate a 20A load, that is connected between SKT3 and SKT4 (i.e positive), with its return SKT5, SKT6. Therefore, I setup the PI model as below.

I get a message that SKT3 does not have any reference pins. So the issue seems to be, that Hyperlynx cannot simulate a load that is connected between the pins of two separate parts. Is there a way to resolve this issue?

Please follow the following steps:
1. Setup all power supplies in the ‘power supplies’ setup panel
a. Setup -> Power Supplies
2. Select all nets that are considered power supplies on the board (also the non-named nets in between components)
3. Select the ‘power network’ button
4. Select the net and the series components by choosing them according to the checkboxes.
a. If ready press the ‘Add to power supply’ button
5. Go to the PI models window and select the VRM for SKT3 & SKT4 (PWR)
6. At all loads press the ‘ AC model reference net’ button to add a reference net : set the SKT5 & SKT6 as reference.
I am trying to simulate a net which includes a ferrite bead but am struggling to assign a model. Only S parameters model is provided and LT/Pspice models. Is there any way around this?
We suggest to include the ferrite bead in the simulation as a passive resistor or inductor and fill the value. Adjust RefDes mapping for HyperLynx to properly recognize part either as resistor or inductor as shown here:

Questions related to HyperLynx SI ALT bundle

Can we have HyperLynx SI ALT bundle license for a local PC?
HyperLynx SI ALT bundle is a unique offer available at a single configuration. It is a floating (network) licence that can be used on a local PC as well, with no limitations.
I cannot start HyperLynx. Error Checking License pops up, how to resolve it?
Please check if you have installed the correct package of software. In the case of the free trial HyperLynx SI ALT bundle, the right installation file can be downloaded from the personal cabinet access to which has been provided by Sintecs.
Please check if you starting a correct exe file. Sometimes Users run the wrong HyperLynx packages of Siemens EDA casually. The name of the package can always be found at the title of an error notification window.
Can we run simulations for EMC testing using HyperLync SI ALT bundle?
EMC is not a part of the HyperLynx SI ALT bundle. Siemens EDA (ex-Mentor) suggests a separate family of products for EMC simulations called HyperLynx Advanced Solvers. This is a more expensive type of solution than HyperLynx SI and it can be quoted by Sintecs upon request, please contact us.
What is the maximum signal frequency available for analysis with HyperLynx SI ALT from SI (signal integrity) point of view?
HyperLynx SI ALT is suitable for frequencies up to 2GHz. Actually, it is limited specifically by IBIS models.
Which license will allow me to simulate the frequencies of the 25Gbps interface?
To simulate 25Gbps interfaces you will inevitably need HyperLynx SI GHz bundle. Another opportunity is working with the engineering team of Sintecs.
How SI capabilities of HyperLynx SI ALT are different from the SI bundle included in PADS Professional?
HyperLynx SI ALT is the same as the SI package inside standard PADS professional.
Regarding exporting a lumped RLC from HyperLynx project using HyperLynx SI ALT, is it possible?
For exporting RLC the General Batch Wizard can be used this way:
RLC extraction HyperLynx
To export S-parameters is it enough HyperLynx SI ALT or not?
HyperLynx SI ALT is not sufficient for S-parameter generation:

   HyperLynx SI ALT  HyperLynx SI DDRx  HyperLynx SI GHz  HyperLynx SI/PI
 Import or use S-parameter models in simulations  –  +  +  +
 S-parameter generation, touchstone viewer  –  –  +  +

Would the HyperLynx SI ALT allow us to simulate DDR signalling, even if it’s only measuring signal flight times?
Yes, it is possible to simulate DDR signals with HyperLynx SI ALT bundle as ordinary signals on the board to measure flight time and signal skew in groups. Also, it is possible to check a termination scheme and topology. It is some kind of manual verification in comparison with DDR Wizard, which also allows doing a lot of checks for JEDEC compliance in automatic mode.
I am now running into an issue where on selecting my net the ground net is also selected which leads to a lot of measurement points being identified on the PCB. Importing the board as an ODB fixes this issue however using the ODB files to create a multiboard projects leads to the connections between boards not being made. With the connection set to short no connections seem to be made in the connection editor.

The problem is caused by incorrect pinnamming in ODB++ files from Altium. Name of the pins should be the same on both connectors, like here:

Altium Designer adds component reference designator to all pins and Hyperlynx cannot match them. If they have S-parameter model for connectors it is possible to try advanced model instead of short. There they can assign any pin to model and build custom mapping.

Regarding selection of GND net probably they need to set GND as power supply net on both boards.
