Thread-less API
There are some functions that you can use to avoid the need for threading, but which still allow you to control the flow of simulation time.
| Threadless functions | Description | 
|---|---|
| 
 | Register the callback code to be called at a simulation time  | 
The advantages of the delayed function over using a regular simulation thread + sleep are:
Performance (no context switching)
Memory usage (no native JVM thread memory allocation)
Some other thread-less functions related to ClockDomain objects are documented as part of the Callback API, and some others related with the delta-cycle execution process are documented as part of the Sensitive API
