I think it's possible (I've not tried it myself).  Try this.  In the schematic, group two sets of components, one using cond1 layer, the other using a different layer, perhaps cond2.   Then try auto generate.

If it does not work, then you should try autogenerate one layer first, lock it in layout, and autogenerate the next one, or a combination of that workflow.

You should use via components to link between layers, so that autogenerate can figure out the placements.

Hope this helps.

thank you Ruslan Ghazalli

If you are doing RF layout (which also includes things like USB 2+ and Ethernet 100+ in terms of impedance matching) I would find it unlikely that one could do the whole thing using automatic tool generation.

What is the actual application - and what is your definition of RF?

hi susan parker,

im designing a wideband amplifier which covers 600MHz to 6GHz. 

Hi Pragash,

Okay, that's a good range.

All the RF traces will need careful impedance matching, and the adjacent ground plane should be via stitched.

If the board is very small, you may just about get away with FR4 but a specialist RF laminate would be preferred, e.g. Isola i-Tera:

hi Susan Parker,

you are not answering my question. please read my question on top again. thanks

all i want to know is how to generate multi layer layout from ADS schematic. for your information, its possible.

hi ruslan,

i hope i can insert via the same way as well using MSub. is that correct? im trying to generate gerber in ads.

Yes that is correct.  You need to specify the conductive layers that the via connects to.  I've included one reference link, there are many others describing via connections in ADS.

hi ruslan,

please help to share the reference link again as i couldn't view it.

Sorry here's the link.
