Cadence n port simulation , bbspice problem

Psyliver

Hello to everyone in the community. I was simulating a mm-wave vco and i had extracted some s parameters from ADS Momentus which i introduced to cadence via a nport while i choose the interpolation method to be bbspice. My problem is that during the past days whenever i choose to simulate a nport with bb spice the simulation nevers ends. The log file states "Peak  resident memory uses=170 Mbytes" and just stays there for hours. There is NO error in the log file. I cannot simulate any file with bbspice not just the vco design. 

Thank you in advance

    This is what the log file states

    Time for EDB Visiting: CPU = 266.959 ms, elapsed = 266.91 ms.
    Time accumulated: CPU = 4.54631 s, elapsed = 9.27344 s.
    Peak resident memory used = 174 Mbytes.

    The simulation just stays there for hours.

    Yesterday it was woking all fine. It is not ordinary something like that to happen.

    Every bbspice simulation just stays in the same point.

    John,

    Beyond looking at Tawna's guidelines, I would suggest contacting customer support. It's pretty unlikely anyone will be able to debug this without seeing the problem and the s-parameter data.
