TINA-TI simulation: Why am I getting error “the circuit cannot be opened or converted into macro”?

Other Parts Discussed in Thread: TINA-TI

I want to add TCMT1100 into my schematic in TINA . I am following the video of Importing SPICE models into TINA-TI .I have spice library for TCMT1100 . I imported t optocoupler.lib and compiled it successfully.

I am getting the below error "the circuit cannot be opened or converted into macro". What could be solution for it?

Hi Sagar,

The problem was with QT1090 NPN model call. It's defined as a 3 terminal device, but while calling it was instantiated as a 4 terminal one. I have corrected the error and created the TINA-TI macro file. Please use it in your design and let us know if you face any other issue.

Thanks!!

Best Regards,

Mahavir Jain.

Sagar,

You might also want to add another point into the PWL for the Photodetector. TINA-TI has a smoothing function that is used for table models but needs more than 2 points to behave properly. Change the line in the .TSM that Mahavir provided:

From:

+ (0,0) (10,10)

To:

+ (0,0) (1n, 1n) (10,10)

This will help with any convergence issues you might experience.
