How to recover the stopped tran analysis from ADE

archive

Though the Spectre user guide provides method to restart the stopped transient simulation,  It is unclear to me how it is done  in Analog Design Environment (ADE). From the default  ckptclock = 1800 option it is clear that every half an hour the  state will be  saved. Where this  state file is  saved and with what name? How to  recover the analysis from ADE?? Is there possibility to  restart  a very long running simulation daily in the  night and stop in the  next morning for other work and resume the simulation before leaving again??

Thanks in advance for any help.

    Hi Hamid,

    The simplest would be to use the Options->Save to re-use the same history, and set the save file to just be a local path (in which case it would be in the netlist directory for each corner). If you're re-using the same history, and using the recover option, it will pick up the state file from the same point it had on the previous run.

    That said, this is hard to scale for multiple runs, because recover doesn't append to the existing results waveform database; it starts afresh from the timepoint in the previous state file. So your measurements may not work properly...

    Getting this to all work properly and cleanly with ADE XL (or Explorer/Assembler) is far from trivial, and would require a fair bit of work from R&D to support. Even merging the results wouldn't be that straightforward, because the end point of the previous simulation may overlap with the start point of the new simulation.

    Regards,

    Andrew.
