Precision Timing
Our precision timing protocol and time synchronization interface, equipped with a kit and software driver, enables users to timestamp models running on a Real-Time Simulator and configure various synchronization setups. This setup supports precision timing solutions across a range of simulation environments.
Connectors
Three connectors offer flexible options:
- First Connector: Synchronize the simulator with an external precision time source using IRIG-B or 1PPS, or generate an IRIG-B or 1PPS signal. Ideal for systems requiring time-synchronous operation and clock signal emulator capabilities.
- Second Connector: Continuously generate a clock signal based on the real-time model’s timestep, allowing FPGA simulations or external devices to sync with the simulator. This feature supports time synchronization in synchronous machine simulation and other real-time applications.
- Third Connector: Receive IEEE-1588 PTP for precise external time synchronization. This allows for seamless integration with time synchronization software and high-fidelity simulation platforms.
About IRIG-B, 1PPS, and IEEE-1588
IRIG-B (IRIG Time Code B) is widely used in the electrical power industry. With a pulse rate of 100 pulses per second and an index count of 10 milliseconds across a one-second frame, IRIG-B provides time-of-year and year information in BCD format, with optional seconds-of-day in SBS.
A pulse per second (PPS or 1PPS) is an electrical signal that has a width of less than one second and a sharply rising or abruptly falling edge that accurately repeats once per second.
IEEE-1588 is a standard protocol for precise clock synchronization in measurement and control systems, using technologies like network communication, local computing, and distributed objects.
