In lab 3(Optimize the Application Code), step 2, does “clean project” need to be performed before “build project” in order to make the modified code take effect?

Hi,
As I followed step 2 in lab 3 (Optimize the Application Code), upon project build completion after inserting #pragma SDS data sys_port(A:ACP, B:AFI) code in mmultadd.h, mmult_1 IP port B was not assigned to AFI port in the Data Motion Network Report as shown in the tutorial. However, if I perform “clean project” before “build project”, mmult_1 IP port B will be assigned to AFI port in the Data Motion Report.

Header files are not necessarily re-indexed upon changes, so what you did was fine. Generally, any changes to accelerator code (or the function definition) should force the tool to re-index and re-compile as necessary.
