TINA-TI: Designing a periodic time-based switch

Part Number: TINA-TI

Tool/software:

Dear Engineers,

I need to build a time variable switch for the following circuit which can be ON and OFF with a specific period, first I chose the following setting for the switch "ton" to have a initial test:

Switch setting:

The result:

Based on the setting it should be ON at 80ms and it should be OFF at 80.0033ms, but as we can see it is not the case, the second issue is that as soon as I change the periodic option to "YES" as follows:

It does not work even:

So, would you please help me fixing this?

In fact I want the switch be ON at 80ms and then be OFF at 80.00333ms and then parodically (3.5 us) repeat the same thing.

Regards
