Accelerating Embedded Software Development with the Intel® Simics® Simulator for Intel FPGAs

Sponsored by Intel

In a traditional FPGA design flow, the main portion of the software development cannot start until hardware is available. Intel provides the Intel Simics simulator for Intel Agilex 5 SoC FPGAs to give developers a vehicle to exercise their software in parallel with hardware development. Developers can run the same compiled binary software files providing the same results in the software’s execution. Software can be developed, debugged, and verified on the virtual platform up to a year in advance of the physical hardware becoming available.
