SOPC Builder Warning (Tightly Coupled Memory)

Please note that SOPC builder will generate the system even if this warning is present.

Anyway the "non-optimal logic" message means that the system could be simplified if you define such addresses that the decoding logic is limited to one bit.

For example, it would happen when your instruction master spans addresses 0 to 0xfffffff and you place TCM base address to 0x10000000; in this configuration the processor decoder needs to test only bit 12 in order to decide if it must access to main bus or TCM.

The aim is to reduce required logic and consequently improve timing.
