Pulse signal in input and output

hi sir

i am attaching a file whose input is a pulse signal. but i am not getting output as pulse signal. can you please debug. it is a simple circuit

manu

I ran this in (the newly released) SystemModeler 4.0.1 and it works:

hi johan,

I do not have latest system modeler 4.0.1, i have system modeler 4.0 but i think it will not matter. and also thanks for attaching the output plot

but if you will notice, the input on data line is a pulse. the output should be pulse delayed by 1 clock period, whereas the output is coming the clock itself. please check and let me know if i am wrong

regards
manu
