GOMACTech 2025 Preview: Improving Productivity with Parallel Simulation (Poster P.9)

Field Programmable Gate Arrays (FPGAs) continue to be a critical part of system designs, and their complexity grows as new technology allows for faster and bigger devices. Naturally, this calls for longer RTL-level simulations to allow for more realistic testing scenarios, but the time spent waiting for results often delays discovery of design bugs.

Fortunately, there is a new generation of parallel simulation technology that can address this problem by substantially reducing walk-clock run time. Specifically, at the upcoming GOMACTech conference in Pasadena, CA this March 17-20, Siemens is delivering a poster that describes the use and implementation of simulation parallelization to address the growing challenges associated with large complex FPGAs, and the ever-increasing time spent simulating for verification closure.

Here is a three-part sneak peek …

1 – Both the testbench and (FPGA-based) DUT are partitioned automatically by the tool

2 – Now, here is the best part (especially dear to users of old parallel sim technologies that failed to do the following): the tool goes on “characterize” the testbench + design, giving the user an estimate of how much an RTL simulation can be expected to improve from the partitioning and parallel sim. technology for a given test. Rephrasing, different testcases will yield different results, and not all testcases will benefit from parallel sim – so it’s quite helpful to see a test’s potential up-front.

3 – Per the above graph(s), for the verification runs that benefit from parallelization, the wall-clock run time improvements can be quite dramatic. My colleague and poster presenter Jonathan Stanley will share data from real-world case studies.

Here is the listing for the poster:
