Control of S2PMDIF

Dear all,

I have characterized my DUT using a vector network analyzer for various values of a control signal, Vcontrol.

Following that, I combined all the s2p files into a single MDF to be read using a S2PMDIF block, with variable Vcontrol, within ADS. May I know if the variable Vcontrol can be controlled by a timed signal or it can only be controlled using a parameter or file?

No one else has this question

Hi Nilesh,

Thanks for the link.

I managed to incorporate a DataAccessController with a S2PMDIF block.

However, when I run the simulation, I receive the following warning message:

"Warning detected by hpeesofsim during circuit set up.
The time dependence of parameter in device 'X2.S2P1.cmp1' is not supported. The simulation result may be inaccurate."

X2.S2P1 refers to the S2PMDIF block.

May I know what is wrong and how I can proceed?

Without looking at the exact project and design, I cannot be sure. I found a document which seems to suggest that this can be ignored:

My recommendation is to send this to your local Tech Support team and they can tell you for sure if this warning is serious or if it can be ignored.
