RAPTOR EXAMPLE DESIGNS

Example designs are installed with Raptor under:

<install_path>/share/raptor/examples (ie: /usr/local/share/raptor/examples) for Project examples
and
<install_path>/share/raptor/tcl_examples (ie: /usr/local/share/raptor/tcl_examples) for Tcl examples

To run one of the examples, cd into any local user directory and run:

raptor --script $RAPTOR_PATH/share/raptor/tcl_examples/and2_verilog/raptor.tcl (GUI mode)
or
raptor --batch --script $RAPTOR_PATH/share/raptor/tcl_examples/and2_verilog/raptor.tcl (Batch mode)

A project directory gets created with all the artefacts generated by Raptor.

A log file gets created too: raptor.log with all the compilation steps logs agregated.

Example designs, please refer to:
<install_path>/share/raptor/tcl_examples/readme_raptor_examples.txt for a complete list of examples.

User design

Synthesis considerations

Each call to the "add_design_file" creates a separate Compilation Unit (In the Verilog sense),
the files in that call share the same macro definition space.

Verilog and VHDL files cannot be mixed in the same "add_design_file" call.

VHDL Libraries are not supported at this time, only individual .vhdl file compilation is.

SDC considerations


A .sdc file (Tcl file with special handling of square brackets[]) can be provided using the "add_constraint_file" command.
The file and contain classic SDC commands, Tcl scripting and set_pin_loc commands.
SDC are honored by the Placement and STA stages.
Synthesis will preserve with best effort the names of the signals referenced in the contraints in order for the Placement and STA to find them in the netlist.
