Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).
There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable.
