Definition
A Stimulus Graph is a scheduling-control mechanism used by STING, a bare-metal, software-driven test generator for RISC-V. In the provided evidence, STING “uses stimulus graphs to enable user control of the scheduling of both the random and directed tests generated.”

[1] Stimulus graphs are used by STING to enable user control over scheduling of generated random and directed tests. source
[2] STING is a bare-metal, software-driven generator developed for RISC-V that produces C++-based random streams and ASM-style directed tests. source
[3] RISC-V verification benefits from combining constrained-random stimulus and directed tests because random and directed approaches have complementary strengths and limitations. source
