a low material density ip block 223 in addition the placement 205 of an ip block includes a wide width power preroute 225 surrounding the ip block which allows for a gradual density increase additionally the placement 207 of an ip block includes a designated area 227 such as a dummy fill pattern or spacing between ip blocks which allows for minimization of the cu thickness and topology variation further the placement 209 and the placement 211 of ip blocks have an efficient floor plan because the ip blocks are orientated edge to edge or side to side also if for example the ip blocks in placement 209 and or 211 have a high material density placement 209 and or 211 provides a better topology for later cmp processing additionally to further reduce topology variation a medium material density block 229 may be selected in place of a high material density ip block capable of performing a similar function fig3 illustrates a representation of density variation of an soc design using a user interface such a topology density aware flow view should contain tile coordinates in which a suggested tile size for model simulations is 20 u03bcm by 20 u03bcm density and surface height as shown the user interface includes a presentation 300 showing a placement of ip blocks 301 a 301 b 301 c 301 d and 301 e having a medium material density and a placement of high material density areas 303 additionally the presentation 300 may include a key 305 that indicates a density fig4 illustrates a representation.
