Riviera Pro

The Riviera Pro backend is used to simulate designs using the Aldec Riviera Pro simulator. Riviera Pro is a proprietary simulator that supports Verilog, VHDL and SystemC.

In order to use the Riviera Pro backend, the environment variable $ALDEC_PATH must be set to the Riviera Pro install path

The following file types are recognized by the Riviera Pro backend

  • verilogSource

  • verilogSource-95

  • verilogSource-2001

  • verilogSource-2005

  • systemVerilogSource

  • systemVerilogSource-3.0

  • systemVerilogSource-3.1

  • systemVerilogSource-3.1a

  • vhdlSource

  • vhdlSource-87

  • vhdlSource-93

  • vhdlSource-2008

  • tclSource

  • user

Configure

During the configure phase, build commands for all VHDL, Verilog and SystemVerilog files are written to a TCL file called fusesoc_build_rtl.tcl. The vlog command is used to build (system)verilog files, and additional options for this command can be specified with the vlog_options parameter in the [rivierapro] section. If the design also contains any VPI libraries, an additional tcl script called fusesoc_buld_vpi.tcl is created with instructions for how to rebuild them.

A top-level TCL script called fusesoc_main.tcl is created to execute fusesoc_build_rtl.tcl, fusesoc_build_vpi.tcl and also any additional files with the file type tclSource found in the design

During the configure phase, FuseSoC also prepares scripts to run the simulation in GUI mode or batch mode. The script fusesoc_launch.tcl contains the command to launch a simulation together with all the extra parameters that were specified on the command line. This can be used for launching Riviera Pro in GUI mode, e.g. vsim -do fusesoc_launch.tcl. Another script called fusesoc_run.tcl is also created to run the simulation in batch mode, e.g. by calling vsim -do fusesoc_run.tcl

Build

During the build phase, the fusesoc_main.tcl script is executed.

Run

During the run phase, the fusesoc_run.tcl script is executed

To rebuild the complete simulation model from within a running Riviera Pro instance, execute fusesoc_main.tcl, or fusesoc_build_rtl.tcl to just rebuild the RTL files. Note that these commands only operate on the exported design.
