Generating and importing MDIF File in AWR22.1

MDIF files are a special type of file that contains multiple sets of data, typically 2 port S-parameter data although other small-signal parameters (Y, Z, H, G) are also supported.

MDIF files are often used as containers for data libraries, i.e. a component vendor can provide a set of capacitor s-parameter data for a whole series in one file and the user can place the MDIF file on a schematic and choose the specific value via the dependency variable as a parameter.

MDIF can be created in a AWRDE project by simulating the design project. In the Project Tab, goto  Output File> Add Output File. Generate N-port MDIF by choosing Measurement Type: File and Measurement: NPORTF and generated MDIF as shown in the snapshot below:

You can find the generated MDIF from the project as *.mdf in the format shown below. The correct format of MDIF is an important aspect otherwise it may give many errors in the AWR software.

The generated or the new MDIF can be imported as a datafile in the project by going to Data File>Right click Import Data File as shown in the snapshot below.

By following these steps, you and generate as well as import MDIF.

Now that you have learnt to create and import MDIF file, just think about these:

•  What is MDIF file and when do we need it?
•  How is the formatting of MDIF or how does it look like?
