+
+Contents:
+
+1) FIFO components
+2) Arria10 IP
+3) Implementation options (LUTs or block RAM)
+4) Synthesis trials
+
+
+1) FIFO components:
+
+  ip_arria10_fifo_sc              = Single clock FIFO
+  ip_arria10_fifo_dc              = Dual clock FIFO
+  ip_arria10_fifo_dc_mixed_widths = Dual clock FIFO with different read and write data widths (ratio power of 2)
+  
+
+2) Arria10 IP
+
+  The IP was ported from Stratix IV by:
+  
+    . copy original MegaWizard <fifo_name>.vhd file
+    . rename <fifo_name>.vhd into ip_arria10_<fifo_name>.vhd (also replace name inside the file)
+    . commit the fifo/ip_arria10_<fifo_name>.vhd to preserve the MegaWizard original
+    . open in to Quartus 14, set device family to Arria10 and finish automatically convert to Qsys
+    . then generate HDL (select VHDL for both sim and synth) and finish to save it as ip_arria10_<fifo_name>.qsys
+    
+  this yields:
+  
+    ip_arria10_fifo_sc.qsys
+    ip_arria10_fifo_dc.qsys
+    ip_arria10_fifo_dc_mixed_widths.qsys
+  
+  The Arria10 FIFO IP still uses the altera_mf package (so not the altera_lnsim package as with the block RAM). The
+  FIFOs map to the altera_mf components to scfifo, dcfifo and dcfifo_mixed_widths.
+  
+  The IP only needs to be generated with ./generate_ip.sh if it need to be modified, because the ip_arria10_fifo_*.vhd
+  directly instantiates the altera_mf component.
+  
+  The instantiation is copied manually from the generated/ip_arria10_fifo_*/fifo_140/sim/ip_arria10_fifo_*.vhd and 
+  saved in the <fifo_name>.vhd file. So then the MegaWizard vhd file is overwritten, but that is fine because it is 
+  no longer needed, it could easily be derived from the original in $UNB and it is still as a previous verion in SVN.
+  
+   
+
+3) Implementation options (LUTs or block RAM)
+
+  The IP FIFO can be set to use LUTs (MLAB) or block RAM (M20K), however this is not supported yet. This would imply
+  adding a generic to set the appropriate parameter in the altera_mf.
+  
+
+4) Synthesis trials
+
+  The quartus/fifo.qpf Quartus project was used to verify that the FIFO IP actually synthesise to the appropriate FPGA resources.
+  Use the Quartus GUI to manually select a top level component for synthesis e.g. by right clicking the entity vhd file
+  in the file tab of the Quartus project navigator window.
+  Then check the resource usage in the synthesis and fitter reports.
+
+5) Issues
+
+  No issues.
