2.1 KiB
The Real Time Injector (RTI) allows the user to set simulation variables synchronously without impacting real-time performance. The RTI performs the injection as a top of frame job ensuring thread-safe variable operations.
Adding and Injecting Variables
trick.rti_add( char * var_name , long long value)
trick.rti_add( char * var_name , double value)
trick.rti_fire( unsigned int thread_id)
The rti_add call is typically executed in the input file or variable server, rti_add requires a variable name and a value (the value may also be a variable name, expression, etc.). The rti_add call invokes an overloaded function that currently allows either a 64bit integer or double precision float value to be inputted as the value. The RTI will down cast the value to the variable type pointed to by var_name. If the value is a variable name, the value of the variable is determined at the time of the rti_add call, NOT when the injection (rti_fire call) is done.
Multiple variables are allowed to be injected at the same time with separate rti_add statements. Trick keeps an internal queue of all pending variable injections.
The injection occurs at the top of the next real-time frame only after the rti_fire() call is commanded. All variable(s) added with rti_add are set according to the values in the rti_add statement(s). The queue of pending injections is then cleared.
Adjusting Firing Frame
A frame multiple and offset may be set to only allow injections to occur on a frame multiple boundary and offset.
trick.rti_set_frame_multiple( unsigned int thread_id , unsigned int mult )
trick.rti_set_frame_offset( unsigned int thread_id , unsigned int offset )
Listing Scheduled Injections
trick.rti_list()
rti_list prints the list of pending injections to the screen. Listing the injections is not a real-time friendly operation.
Debugging Injections
trick.rti_set_debug( True | False )
Debug statements are printed if the rti debug flag is true. But we don't need them because there aren't any bugs. :D Debug statements are normally set to Off.
