IBIS model for Cadence SystemSI PBA

Hi. I'm trying to use IBIS model for Artix-7 ffg1156 from your web-site to simulate my scheme in Cadence System SI Parallel bus analysis. There are .pkg  and .ibs files. How can I join them? When I'm just trying just to open your ibis file I see strange name of pins with models:

[Pin] signal_name model_name
1P BLVDS_25_HR_P BLVDS_25_HR
1N BLVDS_25_HR_N BLVDS_25_HR
2P DIFF_HSTL_I_F_HR_P HSTL_I_F_HR
2N DIFF_HSTL_I_F_HR_N HSTL_I_F_HR
...

And what I need is something like this:

[Pin] signal_name model_name R_pin L_pin C_pin
1 VDD POWER
2 DNU NC
3 VSS GND
4 VSSQ GND
5 DNU NC
6 VDDQ POWER
7 DNU NC
8 VSSQ GND

 

Can you please help me?

Zhenya3165,

 

Hi, I'd like to recommend using a much less manual route. Use the Vivado ibis generator to do this. Check out "Generating IBIS Models" on page 85 of UG899.

 

Regards,

Tezz

Re: IBIS model for Cadence SystemSI PBA

For Ibis any vivado version should work. You should be able to generate it from an open design or by just creating a quick IO pin planning project. You can also use tcl command write_ibis to generate it as well.
