port layer Definition, ADS

[moreho]

hi
can we define port layer in the schematic environment instead of momentum in agilent ads?

thanx

No you can't select a different layer, you connect your port, for instance, to a MLIN and the layer of the MLIN is the port layer.

What are you trying to do?

when i create layout from schematic, all of my parts of my microstrip circuit will convert to their ms shape in momentum window and in the 'Cond' Layer. but sometime some port mapped to another layer that em simulation make error for that reason and want me to change that layer.
im trying to know that can i insted of manually set the layer, set it in schematic environment then when i create layout, automatically the layer of my port or even any of element on schematic map to specific layer that i was defined.

Yes, this is defined by default in the Msub element in your schematic. The parameter for that layer is "Cond1=cond:drawing".

but sometime some port mapped to another layer that em simulation make error for that reason and want me to change that layer.

I don't understand what you mean.

You can place multiple Msub elements in your schematic, and each Msub block can have a different layer for the "Cond1" parameter. Then, in your Microstrip element (e.g. Mlin) you can change the "Subst=MSub1" parameter to use that other substrate block, with the other layer definition.

thanks so very much,
i have designed a large microstrip circuit that this circuit has as many as 30 ports.
in ads 2009, whan i create layout from sch, in momentum i must define type of this ports.
now in ads2014, when do same work, in momentum the ports are in the cond layer and do not need to define their types (like internal or ...).
but it is wonderfull that all of my ports have same conditions in sch, but in momentum environment, two of 30 ports are in another layer, for example here, in "resi, drawing".
then before run the simulation, i must change the layer to "cond, drawing" so simulation can run.
i have only one MSUB in my circuit.
i wonder why this happen.
then i want to know as a general rule that how i can define the layer of my elements in momentum environment, in a controlled manner.

This is on purpose, because the thin film resistor is on layer "resi" and the schematic port is attached to that thin film resistor. If you want the port in cond, just add a short piece of transmission line (which goes to "cond" again).

Note that the layer for the thin film resistor and pins connected to the thin film resistor are defined in the MSUB block.

exactly the picture is my problem.
thats work and i can change the layer of TFR using change the amount of parameter "Res" in the MSUB Block.

i have used TFR only for make a large space like 100mm between two MS Line. thats from an old mistake! but that mistake didnt effect on my simulation results, then i didnt noticed to use Mgap!

thanks in advance.
