i replaced all the interconnects with MLIN
1) please look at the picture below. its looks like a cross. what type of "TLines-Microstrip" i should use here?
2) i replaced terms with port and used MLIN to interconnect between components. Am i correct here?
3) the gate of the device has DC and RF interconnect together. what type of "TLines-Microstrip" i should use here?
i have tried as per your suggestion. now i can see almost the complete layout there but its abit messy because few structure stacked on top of each other. i think i need to have enough space between those structure to avoid this issue. please give me your suggestion.
apart from that, im getting below warning for active devices. is that means layout footprint not available for these devices? im using modelithics library.
1) i have component such as current probe and DC supply in the schematic. am i suppose to remove them before generating layout? does layout generated for DC supply as well?
3) one of my friend suggested this. "Schematic to layout can sometimes be rather iffy if you auto-generate it.* You may have to "pick & place" items from the schematic to layout manually.* In the schematic window, somewhere*within the menus there should be a "place from schematic to layout" option.* You will need to enable snap to pins in layout so your layout elements will snap pin-to-pin.* Also, make sure they are on the same layer, eg COND1"
i think he suggesting to use Layout --> place component from sche to layout instead of Layout --> Generate/update layout. what is your opinion. my circuit is large and complex. what method is recommended for my design.
can we do multilayer PCB using ADS generate/update layout? if yes, could you please tell me how?
It looks like some paths take the wrong direction. You need to check manually where that happens. And there are many nodes that look unconnected (with the light blue diamond symbol).
those node are connected in schematics. why its appear to be disconnected in layout? how to fix that based on your experience?And there are many nodes that look unconnected (with the light blue diamond symbol).
dear dr volker,
i tried searching examples but its only available for basic problem. its not available for complicated problems like mine. even ADS cook book doesn't have it.
if you have any examples to Auto create multilayer PCB in ADS, please share here. it will be really helpful.
its suppose to connects to board ground thru a via..
1) if i want to add more vias, i just more via connection to one node. is that true?
2) MSUB only gives us one layer (T and H). is there any component to define for multilayer board?
3) how to draw ground on top layer for microstrip line? is there any component for that in schematic?
is there any option to auto adjust the length of MLIN to connect automaticly?
i have registered to keysight website and read "schematic_capture_and_layout" pdf. none of the useful information which you are giving listed there!
In the ADS forum, I saw that ADS also has elements for grounded coplanar. I have never used them, because my work ist mostly EM (not schematic).

If you want to EM-simulate it and don't need an accurate electrical model from schematic, you can define another MSUB and map other layers in that MSUB. Than all elements using that second MSUB will draw on the layers defined there.
