Description: This design describes the implementation of FIFO in Virtex FPGAs. For a full functional description see Application Note 131: http://www.xilinx.com/xapp/xapp131.pdf Design Type: ISE (chip v50 BG256 -6) Source Files: fifoctlr_cc - FIFO controller top level. Implements a 511x8 FIFO with common read/write clocks. fifoctlr_ic - FIFO controller top level. Implements a 511x8 FIFO with independent read/write clocks. Inputs: * read_clock_in * write_clock_in * read_enable_in * write_enable_in * fifo_gsr_in * write_data_in[7;0] Outputs: * read_data_out[7:0] * full_out * empty_out * fifostatus_out[3:0] Simulation: Requires the following simulation libraries: Unisims Simprims Behavioural and RTL Simulation are done using VHDL Testbench files (fifoctlr_cc_tb.vhd and fifoctlr_ic_tb.vhd). NOTE: If you are trying to run this example in a read-only location, the design hierachy will not display properly. Please copy the example project to a new location by using either Project Save As... from the File menu pulldown in ISE or some other method of your choice. Copy the example to a location where you have write permissions and the hiearchy will display properly.
