 These tools are part of the Open Real-Time Simulation (ORTiS) framework.
 
-Utilizing solvers generated by these tools and FPGA High-Level Synthesis (HLS), real-time simulation of sizable power electronic systems executing on FPGA devices with 35 nanosecond simulation time steps are achievable.
+Utilizing solvers generated by these tools and FPGA High-Level Synthesis (HLS), real-time simulation of sizable power electronic systems with high frequency dynamics at 35 nanosecond time steps are achievable.
 
 Solvers generated by the tools utilize the Latency Based Linear Multi-step Compound (LB-LMC) simulation method to solve system models.
