Saving .srf Files by Time Interval or Signal Condition in Spectre

dogman4

Hi，friends

    I use adel to sim a long simulation and need to generate .srf files. However, I don’t know when the signal will reach the value I want. I want to estimate a time window and save a .srf file every 100μs within that interval for restarting another simulation. Does `savetime` support expressions like `5m 100u 10m`, and if so, how do I use it?

    Alternatively, is it possible to detect the desired signal level in the circuit, and automatically generate a .srf file with a delay of approximately 100μs after it exceeds the set value? This would save space compared to the method above. 

   My virtuoso version:"@(#)$CDS: virtuoso version 6.1.8-64b 09/03/2024 19:11 (sjfhw316) $"
   My spectre version:Version19.1.0.063 64bit--10 Aug 2019
   Thanks in advance

    There is an event-driven capability in Spectre, but unfortunately it is not supported for the savetime parameter on a tran analysis. Please contact customer support and request that a duplicate of CCR 2115088 is filed on your behalf to request this.

    There is no start:step:stop syntax for save time either. Sorry!
