Anyone know if it is possible in OCEAN to run multiple sims of the same type using the same dataset. For example I would like to run two S-parameter simulations SP1 (w/ swept frequency), SP2 (with swept temp) and have the results stored in the same datafile. This techinique is nothing novel in ADS, but in RFDE I do not see anyway of accomplishing this, OCEAN or not. Also, why is there not a way to do parametric sweeps in OCEAN. Spectre and Hspice have no problem with parametric sweep in OCEAN, why not is RFDE?
It is not possible to perform two SP analyses in a single simulation run in RFDE. The Cadence simulator interface (OASIS) does not support this and so OCEAN (based on OASIS) does not either. As you mention, this is quite common in ADS, but ADS has a very different use model for setting up simulations than does Cadence. You can perform two separate simulations in a single OCEAN script, but then the data ends up in two distinct datasets, which is probably not what you want.
With respect to parametric sweeps in RFDE, it is correct that you cannot do them from OCEAN. RFDE is not compatible with Cadence's parametric sweep tool, so that approach doesn't work. You could perform multiple simulations, sweeping the parameter in OCEAN code, but the results would end up in N distinct datasets, which isn't too useful. To make parametric sweeping work properly, Agilent EEsof needs to add an RFDE-specific sweep command to OCEAN.
