Speed difference between 'DC ParamAnalysis and DC Sweep

Hi folks,

I want to perform multiple parameter sweeps over DC/OP simulations and export the data. Since I'm an intern and only have access to ADE L (due to costs), I made an Ocean script to do so (the code I am using is added below.). I works fine but takes a lot of time to run. However if you perform a DC sweep it goes quite fast. I believe the difference is that in case of a DC sweep, the simulator (Spectre) is innitialized only once and performs all the simulations consequtive while in case of a ParamAnalysis using DC simulations, the simulator is innitialised for every seperate simulation, which causes a lot of overhead. Is it possible to use a ParamAnalysis while not innitializing the simulator for every simulation point (or is it possible to run "nested" DC Sweeps via Ocean)?

Thanks a lot
