End cap/boundary cell in my pdk from LFoundary

Hello everyone,

I am designing a decoder using custom digital placer integrated with virtuoso. I could not find End cap cell and boundary cells in my pdk. There are few cells which I don't understand but I am not sure what are they actually and I could not find their information in DRM as well. I can see filler cells of different sizes, Decap cells of three different sizes, Antenna cells but I could not locate the EndCap cells and Boundary Cells. What are the common names of these cells? I am using LFoundary 110nm. Please let me know if anything is left which may help you answer the query.

I don't know why these two questions are coming at the same place while I placed them in different forums logic design and Mixed signal design

Apologies - I think I mistook the question to be a duplicate (I think you posted another one before which truly was a duplicate). The forum guidelines ask you not to cross-post the question in different forums.

I'll split the post again, but to be honest it's more of a Logic Design question than Mixed-Signal - so I'll leave it in this forum.

Hi, thanks a lot. Because of my whole system I thought it maybe correct forum. But as you suggest this is better suited for logic design. Could you please transfer it to logic design or I need to post it there (this will violate forum guidelines)?

I already split it into a separate post which is in the Logic Design forum here - Decoder standalone synthesis in Genus

Is it necessary to use EndCap/Boundary cells? My chip is going to be mixed and I am going to place guard rings.
