I have a large model, after some work (opened and saved between R2012b and R2013a). The code generation (HDL) becomes extremely slow. From previous 30 seconds to 20 mins for same code generation settings.
Through the process, don't see large memory usage, just CPU are kept 100% from core to core. Can't find out what MATLAB is doing.
I've already tried: rebooting, deleting compiled things, removing code generation folders. None of them helped.
My thought of moving forward to get my speed back is to restore from backup or starting new (which is tremendous amount of work).
Just wondering if there is some sort of purge or rest mechanism already built in Simlink.
