Title: Is it possible to make calculations in ADS in sequnce
Post by DoYouLinux on Nov 27^th, 2010, 9:47am

Hi all,

It may sound strange in the topic. I am trying to run a simulation in ADS. There are two parts in this simulation. One part is to calculate parameters A1, A2 and A3 using MeaEqns. The other part is to use the obtained value of A1, A2 and A3 to fit parameters to a lumped model using Optimization.

Since Part 1 and Part 2 are in the same schematic, when A1, A2 and A3 are being calculated in Part 1, Part 2 is being evaluated at the same time. So, Part 2 is now using values of A1, A2 and A3 which are not final values because the calculation of both part are running simultaneously.

What I would is that:

First, Part 2 is disabled and Part 1 is enabled. Part 1 will then finish its calculation first, so that the final values of A1, A2 and A3 will be obtained.

Second, Part 1 is disabled and Part 2 is enabled. Now, Part 2 is using the final values of A1, A2 and A3 in the parameters fitting process.

---> How could I separate the calculation of Part 1 and Part 2 in sequence like this in ADS ??

Please suggest :-[

ADS has documentation on their test sequencer feature and some notes on how to deal with measurement equations.

I would think that you may need to save the first simulation results in a different dataset (maybe not) and use a data access component (DAC) in the second simulation to access the measurement results from the first simulation.

Hi RFICDUDE,

Thank you very much for the information. It seems what I needed. I will try and see how it works.
