TINA-TI: TINA-TIA and Pspice for TI difference

Behnam Madadnia

Part Number: TINA-TI

Tool/software:

Dear Engineers,

Would you please let me know why Psice for TI is so slow in simulation, but TINA-TI can also simulate the same circuit but much faster, so what do I gain by using Pspice for waiting much longer? basically what are the difference, which make Pscipe for TI that slow?

Hi Behnam,

Basically, accuracy. If you want PSpice to run faster, you can loosen the tolerances. TINA has a different optimization. It's faster by being simpler.

Here are some general instructions on how to change tolerances:
