You have the option of "parametric sweep" in the "Study" section. Right click to open the multiple options and select parametric sweep. You can change any of the parameters you want to change. Make sure the parameter you are changing is itself defined as a variable in the parameters sections and is used in your geometry.

Under the "study 1 ->step 1->study extensions", you may select the "auxiliary sweep". After that, under the parameter name you can add any parameters which have been defined previously.

For the specified range and stepsize, you can use "range(1e-10,stepsize,1)". You should specify your own stepsize, e.g., 1e-2.

Dear Ahmad Usman & Liang Cui,

Thank you for your answers. I have used parameter sweep like this (10,10,100), which means it will sweep 10, 20 ,30...,100. I may not have made my question clear.

I want to sweep from 1e-12 to 1 for an example, how could I sweep like 1e-12, 1e-11, 1e-10,..., 1e-1, 1?

Thank you.

Best Regards,

Bill

The stepsize can be set to any forms including the exponential one. For your case, you may use "10^{range(-12,1,0)}" to control the parametric sweep.

Dear Liang,

Thank you for your help. It saved me a lot of time.

Best Regards,

Bill
