When I do a momentum simulation that results in and S-parameter dataset, the circuit does not pass DC through it's via holes.
The circuit includes via holes that serve simultaneously as RF grounds and DC grounds (for biasing of transistors etc.)
When setting up the simulation, I also include 0 Hz as one of the simulation points. Is there anything else I should do to insure that my via holes pass DC?

I have had this problem repeatedly for the last year or two. Easy to replicate. Rectangular via, metal on top, metal on bottom. Internal ports. DC Simulation. ADS V2003C.
Not sure I want to send the whole simulation to them.

That's why one should work with support on issues of this nature. There are just too many combinations of things that can go wrong and nothing is better than looking at the same model setups to analyze and resolve problems.
I'm not sure how to forward it to you. Can you let me know how to do that?
Thanks.

and log your call including the standard info (company or university name, system handle if you know it, etc.) I'm sure we will deliver a solution to the issue.
