How to Save Data in ADS using ASCI format (by Jiarui Lian):

There are two ways to export the simluation results of ADS into an ASCII format file that that Matlab can use:
1) In schematic (design) window: you will find a button 'start the instrument server' which is the 3rd one to the right of the button 'simulate'. After a simulation, click on 'start the instrument server', a dialog box will pop up. In this dialog box, you just need to pay attention to the following items (no need to change other items):

File Name
Output data format
Read From
File Format to write to:
- Choose MDIF
- You may have selected another format but click back to MDIF, so that 'MDIF Sub File' will show up
- In 'MDIF Sub File', choose 'Generic MDIF'.
After everything is set, click on 'Write to File' and you are done.
Find the file and use it in MATLAB for further processing

2) In 'Data Display' window:

plot or list data you want to export in the window
select it (just click)
go to - menu File:
- - Sub menu 'export'
- - sub sub menu 'write select item to tab-delimited ASCII'
You are done now, and ready to go to MATLAB.
