2014.4 Vivado Sysgen - Crash occurs when incorrect instruction is entered into the DSP48 Macro instruction field


Matlab and System Generator have been found to crash when an incorrect instruction is entered into the instruction field for the DSP48 Macro block.

For example, If I enter (C+P) into the instruction field, when simulation is executed, a Matlab/Sysgen crash occurs.


This is a known issue affecting Vivado Sysgen 2014.3 and 2014.4. 

To work around this issue, remove the brackets from the instruction field. 

In the example above, the instruction should be modified to C+P with all brackets removed.

In Vivado 2015.1, a DRC will be reported when incorrect instructions are entered in the DSP48 Macro GUI.
