customize automatically generated base address in Platform Designer

Hi,

in Platform Designer, I added several IP, such as JTAG, NIOS, RAM, ROM and etc.

The automatically generated base address are: 0x0008_0800, 0x0008_1368, 0x0002_0000 and etc.

I would like to make the least 16 bits base address keep 0, and those base address vary in the most 16 bits. such as: those address look like: 0x0001_0000, 0x0004_0000, 0x0005_0000.

I know I can manually change those base address, however, I would like to set Platform Designer who automatically generate base address whose least 16 bits keep 0.

is there any way to do that?

    No. The automatic address assignment simply selects address spans that do not overlap. There are no options for it. You would have to set these manually.

    Sstrell is right, you have to assign the base address manually.

    Hi,

    The automatically generated base address are: 0x0008_xxxx, 0x0006_xxxx, and 0x0002_xxx.

    I would like to fix one base address to a certain address, for example: fix 0x0008_1100 to 0x0007_0000.

    The questions are:

    1) what is the available base address? 0x0007_XXXX works or not? is there any other base address that is available?

    2) where is the doc that tells me what base address is available?

      1) The base address has to be set so that the address span of the agent interface doesn’t overlap with the address span for any other agent interface connected to the same host. You can choose any address you want as long as there is no overlap. The tool informs you immediately if there is overlap.
      2) There’s no document. Every design is different. Just choose a base address and make sure you get no errors about overlapping addresses.
