Output Files
Golden Gate generates many output files, we describe them here. Note, the GG
CML-argument --output-filename-base=<BASE>
defines defines a common prefix for all
output files.
Core Files
These are used in nearly all flows.
<BASE>.sv: The verilog implementation of the simulator which will be synthesized onto the FPGA. The top-level is the Shim module specified in the
PLATFORM_CONFIG
.<BASE>.const.h: A target-specific header containing all necessary metadata to instantiate bridge drivers. This is linked into the simulator driver and meta-simulators (FPGA-level / MIDAS-level). Often referred to as “the header”.
FPGA Build Files
These are additional files passed to the FPGA build directory.
<BASE>.defines.vh: Verilog macro definitions for FPGA synthesis.
<BASE>.ila_insert_vivado.tcl: Synthesizes an ILA for the design. See AutoILA: Simple Integrated Logic Analyzer (ILA) Insertion for more details about using ILAs in FireSim.
<BASE>.ila_insert_{inst, ports, wires}.v: Instantiated in the FPGA project via
`include
directives to instantiate the generated ILA.<BASE>.synthesis.xdc: Xilinx design constraints for synthesis derived from collected XDCAnnotations.
<BASE>.implementation.xdc: Xilinx design constraints for implementation derived from collected XDCAnnotations.
Metasimulation Files
These are additional sources used only for compiling metasimulators.
<BASE>.const.vh: Verilog macros to define variable width fields.
