Hello

I would be very grateful if you could help me solve this problem in ADS.
*
Simulation in ADS my system shows a perfect result for "schematic system" (my system is well adapted) but with "layout circuit" the system becomes no more adapted.
*
Can you, please, help me to solve this problem, I tried many times and I consulted the forums but unfortunately I can not find a solution.

You will find attached a detailed description of my system.
*
Sincerely,

You have tried to use a schematic "ground" symbol in layout. This doesn't work.

You need to draw a via instead. Then, make sure that the layer with the via polygon is mapped in your substrate as conncetion between cond and the ground plane.
 

Please can you mention the different step necessary to draw the ground plane.
 

The ground plane is at the bottom of the substrate. In Momentum, you have created this already (GND). Just define a via layer in the Momentum substrate that connects top side (cond) with the bottom side (GND), and then draw a via circle on that layer.
 

Looks correct to me:

- the yellow circles (for the vias) are drawn on "cond2"
- in your substrate you have mapped "cond2" as a via between "cond" and bottom GND.

So yes, this should work. The yellow vias will create the connection to ground.
 
With "layout circuit" the system still no adapted :(
 

Maybe you made a mistake with the co-simulation setup, where you connect the EM results from Momentum to the circuit components.
