Hello,Originally posted in cdnusers.org by BobD
Design->Report->Summary... ("summaryReport") contains this information. Here is some sample output:
Total area of Standard cells: 469511.230 um^2
Total area of Macros: 297703.134 um^2
Total area of Blockages: 0.000 um^2
Total area of Pad cells: 587500.000 um^2
Total area of Core: 708425.222 um^2
Total area of Chip: 2286264.955 um^2
Effective Utilization: 3.9201e-01
Number of Cell Rows: 167
The "Total area of core" should be equal to the row area of the block unless unless you've cut rows from the design.
"queryPlaceDensity" might also be helpful. But be aware that it calculates the available area by subtracting the things that take up placeable area (like FIXED hard macros and placement obstructions) rather than simply returning the area of the rows. The intent here is to give you a feel for how hard it is going to be to place the standard cells in the design within the available area.
I don't think there's a natively defined TCL command that returns only the area of the rows in a design, but it would be relatively easy to write a short script that did. Please reply back if that would be helpful.
Hope this helps,
