what does Innovus dbGet command top.insts.cell.baseClass mean ? what are these values of top.insts.cell.baseClass mean?

Question

dbGet command can be used to retrieve all the instances of the top block but exactly what are these values insts.cell.cellbaseClass? how can I change them to point certain other level of hierarchy rather than with going to the top? also what is the difference between get_db and dbGet?

trying to get info and understanding of the innovus built in commands.

Answer 1

The values insts.cell.cellbaseClass refers to which class the insts belongs to, that can be of class block/macro, memory or std cells.

if you want a particular hierarchy you can use this commands.

set hinst [dbGet [dbGet -p head.allCells.name name_of_hier].hInst]

dbGet $hinst.allInsts.name

or you can use the cui command

get_db [get_db modules -if {.name == name_of_hier } ] .hinsts.local_insts.name

dbGet commands used in legacy mode of innovus and get_db is ussed in commun user interface mode of innovus
