what are the precautions/guidelines to place the multi cell row height cells while doing placement optimization ??
 

Most of the tools are able to analyze the multi-height cells. it is now treated as any other cell. Both synopsys and cadence tools handle multi height cells without much user input. Once you have the cells in the netlist....it is used any other cell.

Click to expand...

and if cell height is not integer multiple of your row height then you need to create separate row.
