Hi,
I have loaded the milkyway database of the design to the synopsys ic compiler
how can i get details of all the cells present in the design and the netlist after place and route ?



Thanks
 

report_design_physical -all -verbose

Hi,
I dumped reports using the command you gave,
there is a entry called switch which is taking too much of area compared to total area
there are power switches being used , but there is no chance power witches taking so much area
what might be this cell representing ?
Code:

Thank you
 

The report says you have 2.5k instances of switch cells. That is a lot, you should be able to find them.

These reports are usually based on what the cell LEF file says about each cell. Sometimes that data is wrong. I have seen being counted as std cells, IO cells as bonds, and so on. I wouldn't be surprised if this happens to be a cap cell of sorts.
 


I know all the cell names used in the design , is there a way to get details of a particular cell, like how-many instances a particular cell being used.
