execution order of during actions incorrect

2011-06-07T20:12:03Z

in case of nested states with the top-states having no own exiting transitions Simulink seems to want the top-states during action executed before the sub-states' transitions are tested.
This is different from what is implemented in the code generator right now...

update to stateflow transition label notation

2010-10-04T20:41:32Z

An update to the parsing of Stateflow transition labels is required, because Mathworks changed the syntax:

Originally the syntax was:
[condition]{condition_action}/{transition_action}

Now the new syntax is:
[condition]{condition_action}/transition_action
(no curly brackets around the transition action)

Stateflow seems to tolerate the old notation.

The UCGN parser won't recognize the new notation.

(As a workaround, the old notation can be used until a fix/update is provided)

relational expression parsing error

2010-07-18T19:57:43Z

the "not equal" expression in the non-matlab notation "!=" (legal in Stateflow) is not parsed correctly, leading to a fatal parsin error

Expression precedence error

2010-06-24T19:59:43Z

The expression parser (for stateflow) parses binary expressions combining logical and addition/subtraction expressions in the wrong order of precedence:

a < b - 5
is evaluated as
(a < b) - 5... resulting in "logical - 5"
instead of
a < (b -5)

Replication of array indices in Stateflow code

2010-06-23T22:33:40Z

/* Assignment of StateFlow chart inputs */

for (Idx1 = 0u; Idx1 < 512u; Idx1++) {

UpdateStateSfFcnScopeInst->NewBytesBuffer[Idx1][Idx1] = NewBytesBuffer[Idx1][Idx1];

} /* end of for */
