Generally, HyperLynx doesnt work in Demo Mode. Either you have to request a evaluation license to mentor or you can approach some distributor in India. Generally Eval License is provided for a maximum of one month.
Another good way to try HyperLynx for signal integrity analysis is to take the HyperLynx "Quick Tour," http://www.mentor.com/products/pcb-system-design/circuit-simulation/hyperlynx-signal-integrity/hyperlynx-si-quick-tour?cmpid=8054.
Despite its name, the tour presents an in-depth look at pre- and post-layout with HyperLynx SI. Each chapter starts with a brief description of the challenge, followed by a detailed, step-by-step analysis of an example net.
The tour covers the following topics:
* Designing a Well Behaved Simple Clock Net
* Driver Strength and Overshoot Control
* The HyperLynx Termination Wizard
* Parameter Sweeping
* Reducing EMC
* Analyzing a more complex net: a simple DDR memory example
* Designing a Multi-Gbps High Speed Serial Channel
* Interactively Validating a Clock Net after Placement and Routing
* Interactive Crosstalk Analysis
* PCB Layer Stack-up Editing and Trace Impedance Planning
If you want to try HyperLynx PI for power integrity analysis, log into our online virtual lab, http://www.mentor.com/products/pcb-system-design/product-eval/hyperlynx-online-trial?cmpid=8054. No software installation is necessary.
You'll get immediate, hands-on access to all HyperLynx PI features along with data files and guides for:
* DC drop and current density analysis
* Plane noise analysis
* Decoupling analysis

Do you have another working link?
Yes! It's been a while since I first posted that link. Since then, we've revamped the mentor.com/pcb website so URLs have changed. You can find the HyperLynx SI QuickTour here: http://www.mentor.com/pcb/multimedia/overview/hyperlynx-signal-integrity-quick-tour-4200f7fd-e469-4a7f-9d69-775f17a4e57d.
You might also want to try the HyperLynx SI virtual lab, http://www.mentor.com/pcb/product-eval/hyperlynx-si-virtual-lab, where you can try HyperLynx for yourself.
P.S. Thanks for the tip about the TechNote too. I'll get that fixed!

Hi Mehmet. I want to be sure I understand your question.
The Quick Tour should play directly from this link: HyperLynx Signal Integrity Quick Tour - Mentor Graphics (a different URL than the one attached to your post).
- Is that what you're having trouble with, or is it the videos listed below it, such as 'Power Integrity Modeling with IBIS' and 'Tips for PCB stackup design'?
- If you mean you can't run the demos from the 'Chapter' descriptions in the Quick Tour Contents list, those are all part of the Quick Tour itself. Just launch the tour and click around to the sections you're interested in.
Thanks for your reply.
It helped me
Dear Cathy ;
I am trying to follow module 1 of Hyperlynx Signal Integrity Quick Tour video. I connected to cloud to use Hyperlynx in virtual lab.I set up the given circuit to make simulations to see ring back and overshoot issues.
But my circuit simulation did not show me ring back like in video.
Please find attachments related to LineSim circuit and Virtual oscilloscope results.
What is wrong in simulation?
PS: My 7 days of virtual lab access has expired. Is it possible to renew the session?
Unfortunately, I can't answer your question about ringback. You can, however, keep asking for extensions on your vLab.
Dear agxinmj ;
Thank you for your reply.
Unfortunately model that i used do not have multiple drive strenght options.
I changed receiver side model many times and finally below circuit help me to see ring back issue covered in Module 1 :
Results are not exactly same compared to tutor's but enough for me.
I am facing similiar inconsistencies in Module 2 : Driver Strength and overshoot control. I have selected same models from library (again in virtual lab environment) but still getting different results.For example in module 2 ,driver voltage reaches 5V level but when i run simulation ,it reaches to 4.5V approximately.I tried to increase voltage levels from Setup-> Power Supplies but no chance. I am a bit discoureged about following the remaining modules.
I think tutor's hyperlynx version (v8 i guess) had some issues with built in models(or may be in simulation engine ,who knows) :In module 2 , tutor shows drive strength and toggles between Slow-Weak ,Typical and Fast-Strong IC modeling options. But when he run simulations, Rising edge stabilizes on 5V at 9ns for all 3 cases. But it has to be differ. I think this is corrected in v9.
I decided tol follow remainig modules using virtual lab but do not bother signal shapes and timing anymore.
I have another issue with Hyperlynx SI
I advanced to module 5 of demo:EMC Analysis .I setup below circuit and adjusted clock frequency to 133MHz (as tutor told)
I observed about 15MHz skid to 150MHz on Spectrum Anaylzer.
I adjusted frequency to 175 MHz and results can be found on below image :
I stucked here again
Any suggestions please?
As I see, you are analyzing using Hyperlynx ver 9.0. This has a different simulation engine from what was used in Hyperlynx Ver 8.0 used by the instructor in the training module. This kind of aberration was experienced by me also when same topology when analyzed in Ver 8.0 had different waveform. I replicated the same topology as you have shown in version 9.3 and observe that the waveform are identical to what you saw. EMI analysis showed the results similar to what the tutorial says. I could not understand your concern here.
