TPS51604: Spice model is not compatible for ADS

Hi Atieh,

We don't have other model other than the .lib file. Sorry about that.

Weidong

Hi team,

Why the lib file is not comparable with ADS?

I need the unencrypted HSPICE model that can be imported in ADS.

Thank you

Hi Atieh,

We have requested an unencrypted .lib file. We can send it to you when it's available.

Weidong

Hi Weidong,

Thanks for providing the unencrypted .lib file. However, the lib file is not compatible with ADS.

I have received many errors when I run ADS regarding the syntax error and definition of "if" function. After fixing all of these errors manually, I am still getting errors like:

1) Matrix is singular (detected at node or branch `X16.x_u848.e_abmgate.i1')

Please refer to the detailed info for the sub circuit:

SUBCKT SRLATCHRHP_BASIC_GEN S R Q QB PARAMS: VDD=1 VSS=0 VTHRESH=0.5
GQ 0 Qint VALUE = {IF(V(R) > {VTHRESH},-5,IF(V(S)>{VTHRESH},5, 0))}

2)   Number of nodes with no DC path to ground (topology corrected): 91

3)     Diode `X16.x_u848.d_d11.d1' explosion current exceeded.

Can you please help me to fix these errors?

Thank you!

Hi Atieh,

I'm asking help from other team, will keep you updated.

Hi Atieh,

Just want to make sure, when you import the model to ADS and see the dialog box Netlist Import Options, you should select Pspice as the Input Netlist Dialect. If you use Hspice then it will not work.

Weidong

Hi Weidong,

Yes, I selected Pspice as the Input Netlist file. The Netlist file imported in ADS successfully, but when I run a transient simulation with TPS51604 imported model, I receive syntax errors as I reported previously. I could figure out that the syntax error is related to and/or operators that used in Pspice model. In ADS, and/or symbols are && and ||, respectively. I changed all of them in Pspice .lib file and import it again. This time, I got error for the function definition of "if", and so on.

I can report all the modified sub-circuits that I did in ADS vs the original ones in Pspice model, and we review each of them one by one!

However it will take for ever as it is beyond my time and expertise at circuit model level.  I think the best approach here is that TI Technical team collaborate with Keysight Technical team internally and modify the available TPS51604 Pspice model to be compatible with ADS. 

Please let me know if you can assist me in this manner.

Thanks

Atieh
