Adding The Timing Annotations

For approximate timing:

• In the non-blocking coding style, we can make a note of the simulator tnow in a local variable at the start of a transaction and not return success of the transaction (or a sub-part of it) until tnow has sufficiently advanced.
• In the blocking coding style we can block the caller's thread for the appropriate number of cycles before returning with the result.

• In the blocking coding style, we can compare the delay time so far accumulated with a desired maximum (the quantum for that thread or component or system wide quantum) and if it is exceeded then do a resynch.
• In the non-blocking coding style we can do the same, but non-blocking with loose timing is not commonly used.

The loose timing allows transactions to execute out of order (see later slides).
