 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.  Solvers are generated custom-tailored to a given system model which can be defined in plain-text netlists.

+Solvers are generated custom-tailored for a given system model which can be defined in plain-text netlists.  User defined components in the systems are supported through C++ extensions to the codegen tool library.  Multi-FPGA solver creation for decomposed systems is supported.
 
 The tools include the LB-LMC C++ Solver Code Generation C++ Library along with a Command Line Interface (CLI) tool to allow creation of simulation solvers via either C++ programming or command shell environments.
