I have a model which uses an integrator. I want this integrator to be initialized to a value at start of simulation. During the course of simulation, I am resetting the integrator upon a condition. I want the integrator to be reset to zero and not with the initial value. How to model this in simulink? ie.. to have two different values at start and during the run time

In the integrator block, set the "Initial Condition Source" to external. Then, connect that source to whatever logic you need to set the initial value at t = 0 or to the reset value if t > 0. Maybe feed a Clock into Compare to Zero, and use the ouput of that to drive a Switch that selects either the initial value or the reset value. The output of the Switch is the external IC into the integrator.

I need to generate hdl code for this algorithm. Please suggest suitable method

I can't help with that. But I don't see how HDL code is related to the original question. Maybe you should post a new question about generating HDL code.
