avl_csr_rddata 32 Output Avalon® -MM read data bus from csr
avl_csr_rddata_valid 1 Output Avalon® -MM read data valid which indicates that csr read data is available
Avalon® -MM Agent Interface for Memory Access (avl_ mem)
avl_mem_addr * Input

Avalon® -MM address bus. The address bus is in word addressing. The width of the address will depends on the flash memory density minus 2.

If you are using Intel® Arria® 10, then the MSB bits will be used for chip select information. User is allowed to select the number of chip select needed in the GUI.

If user selects 1 chip select, there will be no extra bit added to avl_mem_addr.

If user select 2 chip selects, there will be one extra bit added to avl_mem_addr.

Chip 1 – b’0

Chip 2 – b’1

If user select 3 chip selects, there will be two extra bit added to avl_mem_addr.

Chip 1 – b’00

Chip 2 – b’01

Chip 3 – b’10

avl_mem_read 1 Input Avalon® -MM read control to memory
avl_mem_write 1 Input Avalon® -MM write control to memory
