Hi All,
I am currently testing this simple open loop SR buck and I am wondering if there is any way to absolutely remove the tiny wiggle at the output?
I tried ttol=0.1ns and also disable fast math option, but it remains.

and if I remove the deadtime circuit, it even makes this weird sudden ringing

I have asked Mike, his suggestion is to limit maxstep down to 10ns…
Which works, but super slow…will appreciate for any suggestion…

I asked about how to do it without making the sim slow?
The suggestion is… use C-block…
Ok… I will need to deal with Trunc() and everything again to solve this
Try this
- change time_tol=1p (i.e. TTOL=1p)
- .option trtol2=0
