The SoC domination observed so far in the ASIC industry is coming to the FPGA world and changing the way FPGAs are used and FPGA projects are verified. The latest SoC FPGA devices offer a very interesting alternative of reprogrammable logic powered with the microprocessor, usually ARM. With new types of devices there is always a need for extended verification methodology. SoC ASIC has so far been the main pioneer for advanced and highly scalable verification methodologies. Due to the complexity and size of such projects, ASIC labs were actually driving EDA vendors to deliver verification solutions for their projects.
With the growth of these projects, hardware emulation became a common tool which was then integrated with virtual platforms and labeled ‘hybrid co-emulation’. This hybrid solution offered a single verification platform for both software and hardware teams. Such platforms allow the performance of verification at the SoC level, allowing the entire project to be verified before the final design code is actually written and available for example, to perform the prototyping.
Hybrid emulation allows the connection of the work environment of software teams using virtual platforms with the hardware engineers using emulators. Why is this so important? The issue is, until now the software portion of the project worked on the virtual models, separate from the hardware portion. Connecting these two domains allows for testing of the project at the SoC level instead of the subsystems level, which in turn increases the coverage of testing and enables the detection of problems much earlier.
