What is the difference between Simulation Results and Simulation Results Database?

fazul

Hi All,

Could someone please tell me what is the difference between Simulation results and Simulation results Database in ADE XL(GXL) ?

My understanding is that Simulation Results is similar to ADE L (psf data) and is what contains simulation results data required

for plotting etc etc.

Then what does Simulation Results Database (*.rdb) contain ? By default they are saved in adexl view directory.

do they also contain  the same simulation results in them (duplicate) ?  

Any comment will be very helpful

Thanks & Regards

  • The Simulation Results Database (the rdb files) contain the simulation conditions which were simulated (e.g. which corners, parameter values, etc) together with the scalar results - i.e. the results of any calculations - the specs that were in force and pass/fail criteria. This means any measurements you performed can be kept, without needing the large waveform databases to be preserved. This data is much smaller, and hence makes sense to keep in the ADE XL view itself. Even computing all those scalar results can be quite time consuming when you've done a lot of runs (which is why that is part of the distributed job) - so keeping the results of any calculations makes a lot of sense.

    It's not keeping duplicates of any data here, really.

  • Thanks Andrew for your quick reply. That made a lot of senses .
