  • You can start with the area summation provided by RTL compiler or any other synthesis tool of your choice. From here on its all rule of thumb calculations. In smaller technologies I have found that densities around 75% is the max a design can route. Factor this in. CTS typically adds about 5% area. This depends on your design, but this is what I have seen. Between CTS, timing power stripes etc add a total of 10% max. Start with this number and try out a cursory floorplan and do a quick route. Hope this helps. Maybe Kari/Bob etc. can share their experiences as well.
