 ## Known issues and limitations
 
-There are some known issues with the `experimental::printf()` and that's why the function is in the experimental namespace. The following limitations exist when using `experimental::printf()` on FPGA hardware:
+There are some known issues with the `experimental::printf()` and that's why the function is in the experimental namespace. The following limitations exist when using `experimental::printf()` on FPGA simulation and hardware:
 
 * Printing string literals %s is not supported yet. You can put the string directly in the format as a workaround. For example: `PRINTF("Hello, World!\n")`.
 * Printing pointer address %p is not supported yet.
