Singal exceed the blowup limit during transient analysis of VCO based ADC

[Ahmad24A]

Hi i am facing the issue that during the transient analysis of VCO based ADC in which some part is verilog A based(like XOR,DFF,AND,ADDER) . But during the analysis it gives an error that "
Error found by spectre at time = 1.41319 ns during transient analysis `tran'.
ERROR (SPECTRE-16384): Signal I(V13) = 1.26726 GA exceeds the blowup limit for the quantity `I' which is (1 GA). It is likely that the circuit is unstable. If you really want signals this large, set the `blowup' parameter of this quantity to a larger value."
While this V13 is my supply voltage VDD=1V .
How to remove this error can anybody help me?
Thanks in advance.

You are shorting voltage source V13 by something. Make this "something" better.

No, V13 is not shorting with anyone . I check this many time but still same error occur.

Yes, you are shorting your supply source by resonant circuit. Show us more details about your vco model. The most probably your model is too idealistic.
