modelling interarrival times

Thanks once again. I actually want to use it for the test bench and want to use it in my real time implementation too.

For the implementation I am planning to do something like the following. I am new to the field of statistical modeling, so kindly correct me if I am wrong.

a. Storing the generated inter-arrival time into memory

b. Set a counter (which is synced to system clock) corresponding to the inter-arrival time and decrement it till it becomes 0.

c. Once the counter is 0, read the frame. will continue till all the frames are read.

to generate arrival times with an exponential distribution, what I usually do is this:

delta_t = - log(u)/rate

where "u" is a uniform random value [0,1] and and delta_t is the interval between two events

I am more interested to know about your implementation. Do you use $dist_uniform or $random for uniform random value. Do you implement log using PLI or is there a native support.
