This reference design is available in many different configurations as shown in the following table. The file name for each configuration is created by concatenating the following variables:


Table 1.  Naming Conventions for Reference Design Variations
Variable Abbreviation Value
Type hip Hard IP implementation
sip Soft IP implementation
Device_family civgx Cyclone IV GX
cvgt Cyclone V GT
cvgx Cyclone V GX
aiigx Arria II GX
avgt Arria V GT
a10gx Arria 10 GX
sivgx Stratix IV GX
svgx Stratix V GX
Data_rate g1 Gen1
g2 Gen2
g3 Gen3
Lanes N/A 1, 4, or 8
User_interface avst Avalon® Streaming (Avalon-ST)
Datapath_width 64 64 bit interface to the Application Layer
128 128 bit interface to the Application Layer

For example, the filename hip_sivgx_g2_x8_avst128 specifies a reference design for the following configuration:

  • Hard IP implementation
  • Stratix IV GX device
  • Gen2
  • Eight lanes
  • Avalon-ST interface with a 128 interface to the Application Layer.
