I'm quite new to layout in ADS. When I opened a new layout and tried to create a new substrate, I only had a limited amount of layers to my disposal. The layers I can use are shown in the attachment to this question. As you can see, I'm unable to use the pcvia1 ,2... layers that I'm used to. How can I get all these layer that I'm used to back?
(If I create a new workspace the problem is gone, but I want to stay in the old workspace as I've already done a lot of simulations in that workspace.)
You probably have the 'missing' layers set to be hidden in this workspace (Show Row not enabled). In the setup for the layer panel enable the Show Hidden Rows option.
Then if you enable the Show Row selection items in the table you can enable checkbox for the required layers so that they are no longer hidden.
