WEBENCH® Tools: TI-Tina model simulation

Hi team,

I use webench and export Tina-TI simulation model to do simulation on startup.

Since I want to put several converter solution with same voltage source in one sch and it takes much time to run the simulation.

Is there any method to make it faster ? I just want to see rough waveform which doesn't need high accuracy. Thanks.

Hi Given,

You can increase the maximum time step to 100n to reduce the sim time.Also note that increasing time step may reduces the smoothness of the curves.

You can also increase DC relative error to 2m and DC absolute voltage error till 10u. These settings are found in set analysis parameters under Analysis tab.

Thanks and Regards,

Atul

Hi Atul,

Thanks for your reply.

The maximum time step is 10G default, what does it means? Thanks.

Hi Given,

Please note that the step size indicates the maximum time present between two iterations of SPICE calculations and the default value is set to 10G in TINA.

It is same as ITL4 in PSPICE.

Please use this support page for more queries on TINA.
