If you synthesize the design you'd want to range constrain i to specify the number of bits necessary to implement i (as a counter in this case). You signed out in another tab or window.
Can anyone help me as to what should be the correction? I'd suggest a separate question might be in order should you need help with the simulation results.

Just use numeric_std as this is the IEEE supported package. are the integers modulo 4 a field? Yes, my password is: Forgot your password? I am impenting a FSM model and using case statements to distinguish states.
Passing different value (link value) from VF page to VF component and display it on screen Why do jet engines smoke? Library 'numeric_std' contains a lot of helpful methods. Why do units (from physics) behave like numbers? Check This Out parse error, unexpected PROCESS ERROR:HDLParsers:164 - "D:/test/test.vhd" Line 77.
I would be glad to see your lending hands. parse error, unexpected IF Thanks! Thanks for this one.
