I believe you can catch exceptions in generators.  At least the 
generator PEP says so and the following works.

~~~ [Code Snip] ~~~
from myhdl import *
def test():
     @instance
     def ex_in_g():
         try:
             for ii in xrange(10):
                 yield delay(7)
             raise StopSimulation

         except Exception, e:
             print("Caught exception %s" % (str(e)))
             raise StopSimulation

     return ex_in_g

if __name__ == '__main__':
     Simulation(test()).run()
~~~~~~~~~~~~~~~~~~~~~~~
