Hi all,
I'm working on a Virtex-4 FX Design with a custom logic fabric and a PowerPC Core containing a dual port BRAM block. The CPU with software application and BRAM block was created with XPS, then the XPS submodule is imported in my ISE Design as system_stub.vhd. The Top-Level is a Schematic, there i added the other user-specific vhdl-moduls as symbols and of course the system_stub symbol. With a simple C Application i get access to the bram and can read and write data to an from. The next step is to get access to the second port of this bram via my vhdl logic. How can i do this? How can i connect in XPS System Assembly the second BRAM port to external ports? Is it possible to get in ISE TopLevel a system_stub schematic with the additonal ports of BRAM like Adresses, Data, RST, Clk, WEN? Is there another usual way to solve my problems?
Every response would be appreciated. Mack
