I tried to compile the FPGA code use ISE 9.1i, I started from
“u2_core.v” as
suggested. However it gives me two errors when I compile the code.
ERROR:NgdBuild:604 - logical block ‘mac_txfifo_int/mac_tx_fifo_2clk’
with
type
‘fifo_xlnx_512x36_2clk’ could not be resolved. A pin name misspelling
can
cause this, a missing edif or ngc file, or the misspelling of a type
name.
Symbol ‘fifo_xlnx_512x36_2clk’ is not supported in target ‘spartan3’.
ERROR:NgdBuild:604 - logical block

Can anyone tell me how to fix this problem? Thanks very much!
