To move a block in the Schematic Viewer, simply hold down the SHIFT key and then use the left mouse button (LMB) to select and drag&drop the block to the new location. Connections between blocks will be redrawn for the new layout.
The two snapshots below are schematics of the ternary adder circuit before and after rearrangement. The second snapshot clearly shows the regular structure of the circuit that the LUT3/LUT4 pair for each bit share common inputs and can be packed into the same LUT6_2.

Nice! How come our FAE didn't show us that. We love PlanAhead.
ReplyDeleteNice to see a decent schematic view in a Xilinx product. However, for those with deeper pockets the Synplify schematic viewer is still the best.
ReplyDelete@Bret, what are the features you like in Synplify but are missing in PlanAhead? I can pass them along if you can share your thoughts.
