Dear All,
I am new to TINA-TI and i saw a cct in "Geting started with Tina-Ti"
The ERC report is all ok but the dc analysis and AC analyses are prompting the message of error "irregular circuit".
Please help me with this issue as i am planning to work further in this application.
An image of the cct is attached.

Best Regards

I don't use Tina, but a couple of things jump out. Your power rails are +1.5 volts and - 2.5 volts. That does not look right, as the circuit appears to be a Wien bridge oscillator, which more usually has symmetric excursions.

R1 appears to be pasted over a line, so it is really shorted out of circuit.
