41.4.2 Xilinx ISE/Vivado

Use the New DVT Project Wizard (menu File > New > DVT Project) to create a DVT project in the same location as an existing Xilinx ISE/Vivado project. All source files and settings defined in the ISE/Vivado project configuration files will be automatically recognized.

If you want to create a DVT project in a different location from your ISE/Vivado project location you must tune the .dvt/default.build file:

+dvt_init_auto
# Note that the compilation root must be specified after the +dvt_init_auto directive
+dvt_compilation_root+/xilinx/project/location

Implementation Note: ISE/Vivado projects are automatically recognized by the DVT build auto-configuration engine. For more details, see Auto-config. When the auto-configuration algorithm detects an ISE/Vivado project layout, it scans the existing ISE/Vivado project configuration files and automatically generates an equivalent DVT build configuration file (for example default.build.auto.1).

Note: The New DVT Project Wizard automatically adds both Verilog and VHDL natures. You can manually adjust this setting.

Note: For an ISE project, the required Xilinx libraries are automatically detected and compiled using the +dvt_init_xilinx directive in the generated auto build file. To manually specify the libraries, use the +dvt_init_xilinx directive in the project build configuration file:

+dvt_init_xilinx+UNISIM+UNIMACRO_VER
+dvt_setenv+DVT_XILINX_HOME=/apps/xilinx/Vivado/2014.2/

# Note that the +dvt_init_xilinx must be specified before the +dvt_init_auto directive
+dvt_init_auto

Xilinx ISE/Vivado Auto-config Specific Directives

Directive Description
+dvt_autoconfig_vivado_sim_fileset+<fileset_name>Auto-config from Vivado project using the <fileset_name> fileset.
+dvt_autoconfig_ise_xise+<xise_file_name>Auto-config from ISE project using the <xise_file_name> file.
+dvt_autoconfig_disable_xilinxDisables auto-config from Xilinx ISE/Vivado project. Fallback to default auto-config.

41.4.2.1 Xilinx Libraries Compilation

In order to compile Xilinx libraries:

  • specify the required libraries using the +dvt_init_xilinx directive

  • specify the Xilinx installation path (ISE or Vivado), unless $DVT_XILINX_HOME system variable is set

For example:

+dvt_init_xilinx+UNISIM+UNIMACRO_VER
+dvt_setenv+DVT_XILINX_HOME=/apps/xilinx/Vivado/2014.2/

The available libraries are UNISIM, UNIMACRO, UNIFAST, XILINXCORELIB, CPLD, SIMPRIM, SECUREIP_VER, UNISIMS_VER, UNIFAST_VER, UNIMACRO_VER, SIMPRIMS_VER, XILINXCORELIB_VER, UNI9000_VER, CPLD_VER, RETARGET, XPM.
