Problems Of Compiling ProcessorHeart VI1 somulator simulink

You have once running well Heart VI1 simulator simulink,and with pentium 4 celeron they take 1mn50:
1)method 1 click run processor VI1 then the Start computong runs infinitely with no signal error compilation,and the phase of starting ckock computing dont start.For ART Compilation it meaning that the sequence of initialisation run infinitely ,or also pile cache memory is insufficient
2)Method 2;Accelerator processor before Run ,and procedure setting C Mex is successful
It is time animation of Simulink Compilationntime simulink VHDL and IEEE 1257 compilation?
