Overview

A Parallelized Fork is a testbench parallelization technique described for eUVM in the context of optimizing the RISCV-DV generator. The technique uses eUVM's fork construct to create multiple tasks and distribute them across CPU threads associated with parallel task executors. It is useful when a sequence contains thousands of transactions stored in a container such as a queue or array: the container is sliced, and each forked task processes one slice.

In the RISCV-DV optimization work, the technique is identified as a suitable approach for large instruction sequences. The eUVM implementation differs from SystemVerilog because eUVM can execute forked processes on multiple cores and can delegate a newly forked process to a specified processor thread.
