LMK1C1106: need help for IBIS simulation setup

KlausWawrzyniak

Part Number: LMK1C1106


Tool/software:

Hello

I’m having some trouble setting up simulations for the LMK1C1106 clock buffer. I'm currently using free tools like the ibischk7 golden parser and Intusoft’s IBIS2SPICE converter to analyze signal reflections in LTspice or PSpice for TI. While these tools work fine with other TI components, the parser throws multiple errors (mostly “invalid keyword” errors) for the LMK1C1106. Subsequently, the converter fails to open the LMK1C1106 .ibs file.

Do you have any idea why the .ibs file causes these errors?

 

I also tried importing the .ibs file directly into Altium Designer for signal integrity simulations. Again, this works for the .ibs files of other TI components but not for the LMK1C1106.

Do you have recommendations on free tools for this kind of IBIS investigation?

 

Thanks, best regards,

Klaus

    Hi Klaus, 
    I am unfamiliar with SPICE models and their modeling. 
    We exclusively use the IBIS models here in our product line. 
    For example, if I use Hyperlynx which is the software we use here in CTS and which we use to validate the model - the model works fine, and I can open it accordingly and choose the appropriate model. 


    I was also able to open the IBIS models within ADS. 

    I would suggest customer reaches out to vendor who is creating this IBIS to spice converter for more info.

    Best regards,

    Hi Klaus and Vincente,

    I am having the same problem as Klaus when trying to import the .ibs file in Altium. 
    It is good to know that the .ibs file can be opened without issues in Hyperlynx. At them moment we unfortunately don't have access to a Hyperlynx license. We will try to find an alternative solution with comparable TI components in Altium for Signal Integrity simulations.

    Thank you for the help!

    Best,
