Mathematically complex RTL blocks can pose an issue with verification. Applying standard System Verilog/UVM verification to mathematically complex RTL blocks is challenging, as developing verification code often requires reimplanting the full mathematical function. This paper will present a methodology for offloading these calculations to a 3rd party software library with established software models that can be used to verify against the Device-Under-Test (DUT) Module. This approach is particularly beneficial when applied to functionality such as Reed-Solomon Forward Error Correction (RS-FEC), where implementing a verification model would consume a disproportionate amount of the design and verification resources. The methodology allows for verification of multiple different DUT elements simultaneously, scales to thousands of parallel tests for large regressions run across a server farm and runs independent of other test frameworks; it can be seamlessly integrated into existing testbenches as plug-in functionality. This solution reduces verification implementation times for mathematically complex functionality without compromising thoroughness or reliability.
