System Console Memory Reading

1,007 Views

Hi, everyone. Today I try to use system console to communicate with DE2-70 FPGA board. I want to know what happens when the specified memory address exceeds the reasonable range. For example,


set M_PATH  0]
open_service master $M_PATH
master_write_memory $M_PATH 0x50000000000000000000000000000000000 0xAB
puts

The on-chip memory specified in the Qsys is only 4096 bytes. I wonder why I still get the correct output on the screen, which is 0xAB.
