Vivado HLS 2012.3/14.3: "Use apcc compiler" option not present in HLS 2012.3 as stated in (UG902)
The HLS 2012.3 (UG902) user guide contains an error regarding compiler options in the 2012.3 version of (UG902):
Page 55 of UG902 (V2012.3) states that the apcc compiler option can be enabled in the project by selecting the "Use APCC for compiling C files" option in the project settings (Simulation Settings).
On the next page (pg-56) of the user guide there is a screen capture of this option taken from HLS 2012.2.
However, in Vivado HLS 2012.3 this option is not present in the project settings.
This will be corrected in a future update.
In Vivado HLS 2012.3, the APCC compiler is enabled by default if the project is a C++ project and it includes the header files for arbitrary precision arithmetic.
