Hello Niloofar Fekri.
Welcome to Intel® Embedded Community.
Please review the following documents:
501645 4th Gen Intel® Core™ Processor based on Mobile U-Processor Line (Haswell ULT) IBIS Model – I/O Buffer Information Specification (IBIS) Models – Rev. 1.0
491323 Haswell All-In-One – Signal Integrity Simulation Models Release Notes For Shark Bay Platform
491321 Haswell Mobile – Signal Integrity Simulation Models – Rev. 0.8
These files are confidential, we are going to upload them to EDC Library, as soon as your request for privilege account is approved we will let you know.
Regards.
Josue.
Thanks a lot. I have some IBIS files for Shark Bay and similar, but they are all for PCH; I need the same files for CPU Haswell. I have some CPU files too, but they are HSPICE; I prefer IBIS models.
So I need an equivalent file to "pnv_ibis_nbook_rev20.ibs" for CPU Haswell; this file is for PCH.
Thank you,
Regards,
Niloofar
Hi Josue,
Thanks a lot for your help. So these files would actually contain something similar to "pnv_ibis_nbook_rev20.ibs", but for CPU Haswell? Because that is what I really require, the other documents I already got from my manager and they are all for PCH or have HSPICE models for CPU.
Thanks,
Niloofar
Hello Niloofar Fekri

Thanks for your patience.

While jc further researches your question I just wanted to point out that https://www-ssl.intel.com/content/www/us/en/secure/embedded/nda/products/glen-forest/mobile-4th-gen-core-ibis-models.html?wapkw=491321 491321 is already on the EDC; it is categorized as Intel confidential. The other 2 documents should be live on the EDC by the end of the day. LynnZ.
Hi Josue and Lynnz,
Thanks for the quick reply and the links. I already have links 2 and 3. The first link is what I need, but I need that for CPU DMI or PCIE, there are already files for USB, I2C, ect. The other files that are actually for PCIE or DMI (in the 2nd and 3rd links) are HSPICE and I do not want to convert SPICE models to IBIS models.
Also, when I try to use HSPICE models for both RX (CPU) and TX (PCH) using my OrCAD PCB designer Professional, for some reason it does not extract the necessary electrical parameters from those files (I guess those parameters are actually not stated in the files anyway and that is the reason); that is why I prefer IBIS model.
Thanks a lot,
Niloofar
Hi again,
Any updates to the question I asked above?
If it happens that you do not have the IBIS model for what I asked, could you please let me know which .sp (spice) file I should use for DMI CPU RX side to convert to IBIS myself? Although, I prefer to get the IBIS from Intel rather than me converting it to IBIS myself.
Thanks a lot,
Niloofar
Hi Josue,
Thanks for the reply. The RX models provided are in HSPICE format, so I need to convert them to IBIS then, but I need to know which HSPICE (.sp) file is the one to use; there are different ones there and none seems to be complete. For me to convert HSPICE fiel to IBIS I need to have an input .sp file that contains the following: Header, pin list and SPICE Input deck and these .sp files do not have these included. I do not see any .sp files containing pin list for instance.
Could you please help me get a .sp file for RX having these contents I mentioned? My work is really stuck on this and I think Intel can only help.
Thanks a lot,
Niloofar
Hello Niloofar Fekri,
Unfortunately IBIS models provided by Intel offers basic signal integrity testing capability only. This is the reason why Intel provides HSPICE files for the high-speed interfaces.
Intel does not offer a complete IBIS model. However, customers are usually able to use the provided HSPICE models to compile IBIS compatible files using their own signal integrity analysis tools.
In your case, the files available have been already sent to you.
Best Regards.
Josue.
Hello Niloofar Fekri,
Just to remind you, the files available for this platform are the following:

Hi Josue,
I do remember that. It is just that they are not in the format that I can convert them to IBIS. Remember I said that for me to convert them to IBIS, I need to give them as an input file to my converter and the input file need to contain the following: Header, pin list and SPICE Input deck.
Thanks,
Niloofar
