using shared vhdl code in customer ipif block

Hi,

I have a small microblaze system with my own ipif peripheral. In this peripheral 
I want to use a vhdl block which is also used in another part of my project. Is 
this possible? Because when building the system, the edk looks in the 
pcores/<peripheral name>/hdl/vhdl directory for sources (where it doesn't find 
the shared vhdl part and I don't want to place the shared vhdl code in this 
directory!).

TIA,
Frank

Frank,

I did this for all my coregen components, but I did it all manually, not 
through the xilinx gui.  I have a folder for my custom IP cores called 
"myProcessorIPLib" and under this directory I created

pcores -> CoregenLib -> hdl -> vhdl

this is the standard directory stucture that xilinx uses.  You can but all 
of your common VHDL files in the vhdl directory.  In your pao file you will 
need to add the vhdl files that you want to compile. so for example, if you 
have a file called tmp.vhdl you will have something like this

lib CoregenLib tmp vhdl

You can change CoregenLib to whatever your peripheral name is, so it's 
probably going to look like

lib myperipheral_v1_00_a tmp vhdl

Once you have modified you pao file, you can instantiate your vhdl file in 
your user_logic.vhd file as you would with any other component 
instantiation.

I've done this before, but I had to do it the manual way.way to do this is 
to create a shared components directory.  You will still need the directory 
stucture
