[Discuss-gnuradio] Question about USRP2 FPGA

[Yabo Li]

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 'MAC_top/U_MAC_rx/U_MAC_rx_FF/mac_rx_ff_core'
   with type 'fifo_xlnx_2Kx36_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_2Kx36_2clk' is not supported in target
