I came across a Cadence command "create_place_blockage" for Innovus tools, which is like this:
create_place_blockage -hinst DT_INST/RESS_CONV_INST -inner_ring_by_side {10 10 10 10} -outer_ring_by_side {5 5 5 5}
But I did not find the documentation of this command, so I am trying to understand what these three options mean:
(1) -hinst something : Does it mean the other two options are dependent on this one? It is like we are going to create a blockage on this hier instance, and the shape of the blockage is determined by the other two options?
(2) I thought "blockages" are just rectangular chunks, in other words, it is just big squares. But what does "inner_ring/outer_ring" mean?
Thanks
