1) In matlab simulink, I want to increment a counter variable if the status of a variable is high. The increment should happen by 1 for every sampling period(100 msec). How to achieve this?

Can you explain how to identify if a variable is high or not? what kind of signal gives you this status? If you provide this signal, let us call it signal. Then you can use a switch block, or a Matlab function block

function counter=fcn(signal)
persistent c
if isempty(c)
     counter=0  %  Initial condition of your counter
end
if signal==1 % if a signal is high
  signal=c+1
  c=signal 
end
