1669	Modelica.Blocks.Sources.BooleanPulse weird simulation results	Adrian Pop	Lennart Ochel	"Hi,\\
\\
It seems we have issues with initialization of:\\
Modelica.Blocks.Sources.BooleanPulse\\
[http://www.openmodelica.org/index.php/forum/topic?id=402]\\
I looked at initialization and event handling at time 0 and there seems to be an issue there:
{{{

$ ./TestSignal.exe -lv LOG_DEBUG
....
initDelay called with startTime = 0.000000
Allocated simulation result data storage for method 'mat' and file='TestSignal_res.mat'

mySrc.y goes to 1 at time 0 when it shouldn't!\\
