I have built my model using Simulink 5.1 (R13SP1) and am using the "Fixed Point Blockset – Sum" block from the library
fixpt_lib_3p1/Math
The implementation of the block involved the S-function "sfix_add". I have since upgraded to Simulink 6.0 (R14) where the block was unified with the Sum block from the main Simulink library. When I build my model, I receive the following error.
Error using ==> rtwgen Error in S-function 'MWsum_block/RemoteSum': S-Function 'sfix_add' does not exist.
I had broken the library links in my model and do not wish to replace each block with its updated version manually.
