C-Simulation Configuration - 2025.2 English - UG1702

The csim options apply to the C-simulation process for validating the design's C/C++ language. Refer to Running C Simulation in the Vitis High-Level Synthesis User Guide (UG1399) for more information.

csim.O

Enables optimizing compilation, which eliminates debug constructs. The default value is false. Compiles in debug mode to enable debugging.

csim.O=true

csim.argv

Specifies an argument list for the behavioral test bench. The <arg> passes to the main() function in the C test bench.

csim.argv=arg1 arg2

csim.clean

Enables clean build. The default is false. Without this option, the design compiles incrementally.

csim.clean=true

csim.profile_tripcount

Enables trip count profiling.

csim.profile_tripcount=true

csim.ldflags

Specifies the options passed to the linker for simulation. This option is typically used to pass include path information or library information for the C/C++ test bench.

csim.ldflags=ldExample

csim.mflags

Provides options passed to the compiler for C simulation for speeding up compilation.

csim.mflags=mExample

csim.profile_tripcount

Enables loop trip count profiling, default is false.

csim.profile_tripcount=true

csim.setup

Creates a simulation binary in the csim directory of the current HLS component. You can launch simulation later from the compiled executable. The default value is false. Simulation runs after completing setup.

csim.setup=true
