Subject: [oc] Problems with AX8 and Xilinx XST

I've been testing the AX8 core on my SpartanIIe board. I used Synplify for
syntesis, and the core works really good in hardware, (good job Daniel !).
I've used AVR a lot before and i can resue my code with it.

The problem comes when i try to syntetize it using Xilinx XST (ISE 5.1i),
its generate a lot of warnings and the core does't works well, particulary
the ALU seems to get crazy (1+1=128 żż??). What limitation has XST to can't
syntetize well this core ? This also occurs with others cores ?


    Thanks
