There has been much written about the use of processor models to assist in the development of software. Back in the 1970′s the early versions of Unix on a PDP11 included a simulator of the Motorola 6800 – one of the first Instruction Set Simulators made readily available. It ran very slowly and its focus was to explore the details of the instructions. Today processor models and simulators can have various usage targets.
The models listed on this site, risc-v-microcontroller.com, with title ‘Simulating a RISC-V Microcontroller using the Imperas OVP Fast Model Simulator’ and tagline ‘Using the Imperas OVP RISC-V Fast Processor Model to simulate a RISC-V Microcontroller’, are all available from OVP and are written to be Instruction Accurate and are targeting the development of embedded software. Please search elsewhere for models to be used to test pipelines, cache behaviors, branch predictors and other aspects such as low level cycle/cache performance of CPU architectures.
