18.104.22.168. Creating an Object File From OpenCL Code
Use the fpga_crossgen command to create library objects from your OpenCL code. An object created from OpenCL code contains information required both for emulating the functions in the object and synthesizing the hardware for the object functions.
The fpga_crossgen command creates one object file from one input source file. The object created can be used only in libraries that target the same Intel high-level design tool. Also, objects are versioned. That is, each object is assigned a compiler version number and be used only with Intel high-level design tools with the same version number.
Create a library object using the following command:
fpga_crossgen <source_file> --target target_HLD_tool [-o <object_file>]
where, target_HLD_tool is the target Intel® high-level design tool for this library. This parameter can have one of the following values:
Target this object to be included in libraries for kernels developed with the Intel® FPGA SDK for OpenCL™ .
Objects built for the Intel® FPGA SDK for OpenCL™ are not operating system-specific. The objects are combined as Intel® FPGA SDK for OpenCL™ object files (.aoco).
Target this object to be included in libraries for components developed with the Intel® HLS Compiler.
Objects built for the Intel® HLS Compiler are combined as operating system specific object files (.o on Linux). You cannot use objects created on one operating system with the Intel® HLS Compiler running on a different operating system.
If you do not specify an object file name with the -o option, the object file name defaults to be the same name as the source code file name.
