Address decoding sometimes does not work #5

I have a simple Wishbone system with one master and two slaves. One slave has a baseaddress of 0xf7810000 and a size of 0x00000100, and the slave select of this slave in the generated VHDL file is:

P2020_SPI_ss <= '1' when P2020_adr_o(31 downto 8)="" else '0';

Could someone look into this? Thanks.

Changing the string comparison operator (ge) to the numeric comparison (>=) operator on line 1388 (and 1401, 1415, 1429) does not help in this cae.

It's fixed by changing (ge) to (>=) in the crossbar section of the address decoder on line 1455, 1468, and 1482.
