Xilinx ISE 14.x Design Summary Window does not update or refresh

I have had this one project and I have moved the directory around multiple times. The main issue here is that I can fully go through all the stages of Sythesize - XRT, Implement Design as well as Generate Programming file and the "Design Summary" does not change, ever. The design completely runs and I can find all the reports, but that design summary always stays the same.


This is solved by right clicking on the shaded in reports . Right clicking on "Design Overview" and then "Reset Report List..."

Total number of in the design exceeds the capacity for the target device.


 Occasionally,

You may run into this:

Pack:2925 - The total number of RAMB18s andRAMB36s in the design exceeds the capacity for the target device.

Map:237 - The design is too large to fit the device.  Please check the Design Summary section to see which resource requirement for your design exceeds the resources available in the device. Note that the number of slices reported may not be reflected accurately as their packing might not have been completed.

The best way to check how much you design exceeds capacity by, especially if it is BRAMS is to generate the files on a larger device and see how much resources it uses, this will give you a better estimate of how much to trim your design by.
