Vivado 2016.1 : Arithmetic operation with ap_fixed (N,M) Where N is greater than 64 produces incorrect C Simulation Results


When using Vivado 2016.1 and performing an arithmetic operation with ap_fixed <N,M> where N > 64, C simulation results will be incorrect.


This is a known issue in Vivado 2016.1 and will be fixed in the 2016.2 release.

This issue affects C simulation only, the results of synthesis and co-simulation are correct.
