Compiling and Elaborating Your Design
+spl_read
Treats output ports as inout ports.
Compile-Time Options That Slow Down Compilation
-gen_asm
Generates assembly code instead of directly generating native
code. Can increase compilation time up to 20%.
-gen_c
Generates C intermediate code instead of directly generating
native code. Can increase compilation time as much as 3x.
-comp64
Compiles in 64-bit mode for 32-bit simulation.
Compile-Time Options That Slow Down Compilation but Speed
Up Simulation
-O3 or -O4
Applies more than the default level of optimizations when
generating C code intermediate files and compiling them.
Applying more optimizations slows down the C compiler but
speeds up simulation.
Compile-Time Options That Speed Up Compilation but Slow
Down Simulation
-O0
Turns off all optimizations when generating C code intermediate
files and compiling them. Turning off optimizations allows the C
compiler to finish sooner but the design simulates slower without
these optimizations.
