Data memcheck
ConceptA riscv-formal verification check that exercises a core's load/store data path by emulating a single read/write word of memory at an unconstrained address and verifying that the reads and writes reported through RVFI remain consistent.

Overview
Data memcheck is a verification check used in the riscv-formal framework to validate the data memory portion of a RISC‑V core. It is part of the suite of "other checks" that are not yet managed by genchecks.py and that cannot be implemented using the standard RVFI wrapper interface alone.

[1] Data memcheck is one of the 'other checks' in the riscv-formal framework that are not yet managed by genchecks.py and cannot be implemented using the standard RVFI wrapper interface. Verification procedure - RISC-V Formal documentation
[2] Data memcheck adds a memory abstraction that only emulates a single word of memory at an unconstrained address, and that word is read/write. Verification procedure - RISC-V Formal documentation
[3] The check tests whether writes to and reads from the memory location, as reported via RVFI, are consistent. Verification procedure - RISC-V Formal documentation
[4] A reference implementation is provided as dmemcheck.sv in cores/picorv32/. Verification procedure - RISC-V Formal documentation
[5] Data memcheck has been superseded by the equivalent standard bus check. Verification procedure - RISC-V Formal documentation
