Hi,
I am not able to find a solution to get the outputs for phase noise in an oscillator at different frequencies along with the input parameters.
I am varying 7 parameters with specific values in each run of phase noise for an oscillator circuit using the parametric analysis method.
At each specific set of 7 parameters, I am plotting the phase noise vs frequency graph ranging from 10Hz to 1M Hz.
I want to have the output preferably in .out/csv/.m format (so that I can easily import them to Matlab)
The output contains an array of phase noise values for a particular set of design parameters at a given frequency, all the values of design parameters (in separate rows/columns) used for that particular run. This whole set varies with different frequencies.
My current ocean script looks like this, I am not able to figure out how to achieve the objective.
