i have problems with runing an example-model "halfadder" which is provided via the package:
Modelica.Electrical.Digital.Examples.HalfAdder
Following the code-snipets:
C:\...\OpenModelica-1.4.0\OpenModelica1.4.0\ModelicaLibrary\Modelica\Electrical\Digital.mo
...
package Digital
"Library for digital electrical components based on the VHDL standard with 9-valued logic and conversion to 2-,3-,4-valued logic"

model HalfAdder "adding circuit for binary numbers without input carry bit"
import Modelica.Electrical.Digital;

<P>
This example demonstrates an adding circuit for binary numbers, which internally realizes the interconnection to
And and to Xor in the final sum.
<br>
<br>
1 + 0 = 1<br>
0 + 1 = 1<br>
1 + 1 = 10<br>
0 + 0 = 0
<br>
<br>
<b>a</b> + <b>b</b> = <b>s</b>
<br>(The carry of this adding is <b>c</b>.)
<br>
<br>and
<br>
<br>
<b>a</b> * <b>b</b> = <b>s</b>
<br> (It is an interconnection to And.)
<br>
<br>
<b>a</b> * <b>b</b> + <b>a</b> * <b>b</b> = <b>a</b> Xor <b>b</b> = <b>c</b>
<br>(It is an interconnection to Xor.)
<br>
<br>
<pre> <b>a</b> <b>b</b> <b>c</b> <b>s</b> <b>t</b></pre>
<pre> 1 0 1 0 1</pre>
<pre> 0 1 1 0 2</pre>
<pre> 1 1 0 1 3</pre>
<pre> 0 0 0 0 4</pre>
<br>
<br>
<b>t</b> is the pick-up instant of the next bit(s) in the simulation.
The simulation stop time should be 5 seconds.

Could anybody help me with this (simple ?) problem ?
Thanx in advance,
