Interconnecting busses of different elements ?

Hi,

I am trying to make a simple project with Quartus prime Block diagram/Schematic file. I am wondering how to connect two busses which are of different sizes. For example I need to connect an 8bit bus Test_bus8[7..0] to a first 8 elements of a 32 bit bus say Test_bus32[31..0]. How is this done? Also is it possible to connect the 8bit bit bus to element 8-15 of the 32 bit bus? Is there a way to map the elements of one bus to elements of the other bus?

Are there any documents/tutorials which cover these basic elements about the software?

Warm Regards

Rohit

    Hi,

    Yes, this feature is available in Quartus simply mention the bus names with specific bus width, here example like Test_bus32[15..8].

    please refer the link below for your reference & try to apply to your schematic & if you still unable to do provide the project file or screenshot.
