have a mode working where tool will generate a theory using the simulink types, as well as an constraints expressed in the pvs types. for example if input is x:real, but in simulink diagram input is int8, will create a theory where input is of type int8, copies a pvs theory of the types to the pwd, currently using integer subranges for types, and real for floating pt types, not sure if I should use IEEE754, might lose test case generation with this. Typechecker forces proving that no over/under flow for outputs, this is not always automatic, and grind seems to have trouble with it sometimes.
